Don't Fall for These 5 Pedalboard Myths!

[@VertexEffectsInc]

If you have a pedalboard myth that we didn't cover in this video, let us know in the comments below!

[@cheesy6516]

One I hear a lot is starving pedals of power causes damage. Little do they know many pedals, such as fuzz, can sound even better when starving the power by a hair to get the dying battery effect.

[@VertexEffectsInc]

@@cheesy6516 under powering shouldn't be an issue, it's over powering them that is. Restricting voltage will sound different, you can watch our Battery Power Supply demo to get a sound reference for that.

[@isaacramirez3729]

So, I hear that you need an input and output buffer but, I've also heard that all pedals are buffers when you turn them on. If my Bass Compressor has an input impedance of 1Mohm and an output of 600ohm, is that a sufficient input buffer or would you still recommend sandwiching the board?

[@VertexEffectsInc]

@@isaacramirez3729 yes, but just like all buffers, there are good and bad ones. A pedal on is a buffer, but the buffer could, and likely does suck. If your bass compressor is always on and is 1M, that will work for the input buffer, but you'd still want an output buffer. If you got a higher quality dual buffer it also wouldn't hurt anything.

[@thiagodiascosta3582]

Doesn't matter if you like the guy or not, there is no denial that this is just good information given freely by a knowledgeable person. Thanks a lot for this. Also, one question: does 18v increase the noise floor on overdrives/eqs also? I always heard people say the opposite: 18v increases headroom and lowers the noise floor. I have 3 pedals that take 18v (Cmats Signa Drive, Cmats Ratified and Wampler Equator), and I always run them at 18v "just because". I read everywhere on the internet that these Cmats pedals at 18v sound better, have more headroom, are more dynamic and with better note separation. Aside from the headroom, do you think that there is any grounds to claim that pedals become "clearer" and with better "note definition" at 18v? To be really honest I can't say I noticed any difference ever. Also, regarding the Equator, Wampler claims it is designed to "sound best" in 9v, but I just can't see how this could be true. I also run it at 18v "just because". Herd behavior is real...

[@VertexEffectsInc]

Hope you enjoy the video. 18V typically increases the noise floor. Headroom also goes up. You may run them in conditions where you don't need the headroom to get the sound you want. There is no reason to run it at 18 if you don't have to or you aren't getting a more desirable tone if the pedal can still operate on 9V based on its design.

Appreciate your passion and perspective Mason. #1 Of course, all connections are not made equally; people’s experiences and requirements are also not the same. I was doing 3 to 6 month international tours pre-covid (where I’m my own tech too - reality for majority of working musicians), I’ve had more failures with soldered instrument cables than with my Free The Tone solderless patch cables. Mackie cable tester reading is the same if the cable is good. Regular maintenance is required either way. #2 Run my “input” buffer after fuzz, octave, boost and OD, like a “normal” person. 😉 #3-#5 TOTALLY agree with you! 🤓

[@VertexEffectsInc]

There can be individual experiences but both being made equally well with the same wire, soldered will always prevail and prevail over time as the connections will not oxidize.

[@jameshalbert181]

B+ running cables together it's the only one I got wrong. I figured out the 18v with an sp comp . Moving the goal post is a good analogy. More noise because I had to dime it to get it to compress to my liking.

[@bryangiasson683]

Hi, touring musician here.... After #1 I gave up, stagger your input and output jacks and maybe I can start using soldered cables again.... but I can’t tell you how many 6in patch cables I smoked having to twist them to get them to work where I wanted my pedals to be. I changed over to George L’s Solderless cables years and years ago and never been happier. I run A/B stereo style pedal 5 pedals split into two other boards with 5 pedals each running to separate amps 15 pedals total so I went from running 7 extra feet for 6in patch cables to just under 20 inches of cable and it had a HUGE effect on my tone.

[@VertexEffectsInc]

I guess you're presuming in all this that the patch cable quality was good when you were using soldered, and my guess is that it wasn't high quality. Most quality patch cables, ours included, have lifetime warranties and can be made to any length you want from 3" to 42" so you can order whatever you want and most companies are doing that now. When's the last time you saw a lifetime warranty on a solderless cable - I sure haven't.

[@jasons5916]

The reason why running DC power cables next to audio cables is ok while doing the same with AC will cause noise is because DC cables produce a steady magnetic field while AC doesn't. The magnetic field produced by a cable is proportional to the current flow and changes directions when the flow changes direction such as when AC oscillates. Noise is caused by the magnetic field inducing a current in another wire (your audio cable) that is inside the field, but current is only induced if the magnetic field is changing. DC field doesn't really change, but AC oscillates at 60Hz (or 50Hz depending on your grid), so DC will not induce noise into your other cables, but AC will.

[@VertexEffectsInc]

Correct!

[@vk3fbab]

True except if your DC supply goes out of regulation and induces a ripple on the output. You'll get a lower magnitude AC ripple that could be induced on any nearby audio cable. But a good supply should maintain regulation up to the maximum current.

[@telecasterday]

Thanks for the debunk on Dc cables vs audio. I had read that and I remember looking over at my gear and thinking "if that's true, I should have all kinds of noise?" It stuck in the back of my brain and the next time I was setting up a board I was trying to keep the 2 separate. I kinda gave up on the idea. Imagine if it were true! We'd have to set things up quite differently.

[@VertexEffectsInc]

Glad it was helpful!

[@kernowcalli3312]

Do you still recommend a buffer first if using fuzz pedal first in chain?

[@VertexEffectsInc]

Depends on the fuzz, but generally buffer after fuzz.

[@Greenmantislives]

What about overdrive? Buffer before or after?

[@MikeSadlerAU]

Less myth, more a buffer question Mason. When I split my drive pedals chain at a buffer (I have a Humdinger, but building one of your designs for my 'other' board) to my Dry amp (let's call that Out 'A') and the rest of my effects (let's call that Out 'B') before going on to Wet amp(s), those outputs A & B are *usually* marked 'buffered' and 'isolated', respectively. Often, the isolated output will also have a phase inverter (just swapping the hot and cold?) and will be marked as un-earthed, or have an earth-lift switch. I *imagine* it would be best to 'save' the phase-switchable output to go through my time based Wet effects, so that if they ended up out-of-phase at the Wet amp speakers, recorder inputs, etc, I could *just* flip it... and that would mean the drive pedals to Dry amp input is coming out of the *plain* buffered output. Are my assumptions correct, incorrect, or *it doesn't really mater*? Is isolated/phase-shiftable/earth-liftable Output B (typically) buffered like the plain Output A as well? Please :-)

[@VertexEffectsInc]

Well you wet effects could invert just as easily as your dry effects could invert the polarity. Those switches are really to ensure that your amplifiers are in the proper polarity (phase is not really the right word although these two terms get collapsed). Typically the isolated output will sound worse...most transformers can't take a lot of signal output for this application and are prone to low-end distortion. If you're using it as a splitter it probably doesn't matter much which goes where. The polarity control is more to correct the amp polarity, not stuff in the pedals.

[@bobbarcus8310]

I have some early 1980s DOD pedals that use 1/8 in plugs I have a old DOD power supply but it is not isolated What can I use Will it make too much noise if I use the DOD and use Boss psa120 for my other Boss pedals thanks

[@VertexEffectsInc]

You can buy 1/8" cables from Voodoo Lab to use with any normal power supply. The 1/8" is just a different barrel size, it won't change the noise floor using a supply with a 2.1mm barrel size. You'll just need an adaptor or a new cable to go to your power supply.

The Nu-tube is gain stacked with a mxr Zakk Wylde overdrive. It gives it a little bit more headroom, more of a big open sound. Like you said it takes some compression out of the sound. I run them into two 50 watt tube amps. An old Carvin X50B with 4x12 cab and a Marshall jcm800 4010 combo. Loud and unique!

[@ScottyBrockway]

Possible downsides of switching mode power supplies is "beat tones", particularly with pedals that use charge pumps. Another problem with them is when they fail, it's often catastrophic and can run wall voltage down to your pedals as they generally don't have any protections for that. Each power supply design has it's plusses and minuses. Electromagnetic shielding is easy to add to linear supplies in the form a faraday cage, older power supplies often have this built in to the form factor they are encased in.

[@VertexEffectsInc]

This would be a problem with the design of a particular switch mode supply or the design of the pedal using a charge pump - not something inherent in either. Yes charge pumps (or any pedal with high frequency) can cause this kind of problem. This is because it is a poor design. When a high frequency that is “above” audible is in the output of one pedal and the second pedal also has a high frequency with the audio (from any high frequency circuitry - in this case the high frequency oscillator for the delay device) both frequencies create a sub harmonic that is in the audible range and it will change depending on the chorus or delay setting (high frequency oscillator) so the noise will change with setting. This stuff happens when the circuitry is poorly designed, corners are cut, or the engineer does not understand enough electronics. The very old devices were built as cheap as possible with no thought of other pedals in the chain and the devices they had to work with (let alone affordable) were pretty bad back then. I am surprised this does not show up a lot. It really should be a big problem often based on most of the designs I have seen. Most people are just lucky, we should be seeing a lot more of this problem in reality.

[@ScottyBrockway]

@@VertexEffectsInc Yeah we should see it more, I've seen it a few times, it's very annoying and hard to track down sometimes as it can be an interaction between two pedals and the supply. Some inexpensive effects (I won't name names) still can have this problem. The power supplies should filter out that high freq noise too (again not naming names).

[@andrewwest2386]

It's always a tough gig making blanket statements... There is more background knowledge in your head informing your opinion than you can reasonably explain in a few minutes. There's often a kernel of "It depends..." in these answers somewhere. On the linear vs. switch mode power supply question: I've seen examples of (admittedly "poor") switch mode power supplies that emit high-frequency hash that some pedals can pick up as noise with some "whistles". I've also recently been through a design exercise and made myself a very efficient linear supply (with multiple types of interference suppression) that measures to have lower losses and better power factor than many of the switchers claim to have. But I've also designed it specifically for the way I use things and it isn't as flexible as an SMPS. Anyway, my point is that a "well designed" linear power supply can be quieter and more efficient than a "not so well designed" SMPS. Yes, you need to take care with locating it so that the magnetic field doesn't interfere with your pedals (the only thing I've had a little trouble with is a Dunlop Crybay...), but one should also take similar care checking out an SMPS. Your point is well made as a "general" comment, but I don't think it's quite as black-and white as it came across. YMMV. It's probably similar with buffers: As you say, they aren't all equal. I think that with most things about our rigs, we need to find what works for us. Unless there is a glaring problem, it is sometimes difficult to be objective and decide that I made a bad choice and should change something. And maybe I'm being overly defensive of my linear power supply because I invested so much time into it...

[@VertexEffectsInc]

I don't think anything in here that I say is disqualified by what's stated in the video. With respect to the power supplies, taking two equally equipped supplies, both well made to the industry standard, one linear - one switching. The switching is going to be as quiet, more efficient, lighter, work anywhere in the world (unless the linear supply has a multi-tap transformer for offsets for each country), will provide more power and current to a cost equivalent linear supply. Furthermore you're not going to have any risk of noise depending on where it sits in relation to your pedals or interacting with say your wah inductor. It is the magnetic field leakage that most people don't understand as the critical factor between linear and switch mode power supplies in the context of a pedalboards. There are a lot of power supplies claiming to have toroids, but they are not really. A true toroid has a round, not oval, magnetic core and even that's not nearly enough. It has to have equal winds fully 360 degree around this magnetic core or it leaks magnetic field. Also any hold down material down the center can cause spurious leakage. If the center hold down bolt is magnetic material, it has to be perfectly centered or will cause issues. Non-magnetic stainless steel (not al stainless steel is non-magnetic by the way, there are many different stainless steel grades) and even then, a Toroid leaks, it just does so in a controlled manner and at a low level on axis of the hole where a steel chassis or steel can control it. With buffers, there is a standard for neutral. A buffer shouldn't add color by definition and the litmus test for a good one should be guitar plugged into amp with a 10ft cable of your choice as the reference. You won't be able to get a pedalboard with 30 ft. of cable, 10 pedals, and a mix of true bypass and buffered pedals to get the same tone as a 10ft cable unless you're willing to adhere to certain buffering guidelines and qualities, and even then you might not fully get back to the "neutral" reference. The 1M input impedance and 100 ohm output impedance is a good general starting point. Most buffers are way higher on the output Z especially - 1K is typical. In practice 1K won't do very well with any amount of capacitance on the output and the more it has to drive the more unstable it becomes. You may like this sound - but it's not a buffer. Buffers aren't distortion generators.

[@andrewwest2386]

@@VertexEffectsInc Thank you for responding and the additional info!

[@The_Ricardo_Sa]

I've read a bunch of descriptions for power supplies online, none of them mentions switch or linear. All of them claim to be 'isolated' and 'noise free'. From a £20 to £250. How am I going to find this out prior to purchase if manufacturers do not include this information? Or am I let to go though countless forums looking for the information? It shouldn't be that difficult to state this in the product description.

[@1981ASURay]

There will be clues in the description. Looking on Sweetwater at the CS12 and Zuma, for example, you see switch-mode, switchable, and worldwide in the description. The Voodoo specifically says in its description that it has a toroidal transformer.

[@benstolt]

Great video. The only thing I can’t agree with is regarding buffers - TL072 make excellent buffers in the right configuration. Anything else is silly mojo talk. Also - the power supply myth need some clarification: a linear power supply will feed cleaner DC (if it’s filtered properly). However in recent years, higher end switch-mode PSU’s have become good enough that the difference in result for our application is negligible, thus favorable for size, cost, variable input voltage and lastly lower interference, as mentioned in the video. With that said, a toroidal transformer will have most of it’s magnetic field on the inside of the coil, meaning that it’s usually safe to put a pedal next to it. In many conditions it’s perfectly fine to put things on top too, depending on type of pedal (a pedal which internal amplification, i.e overdrive/distortion is generally undesirable, while e.g a tuner most often works just fine). Conclusion: I’d rather have a quality linear PSU (with a toroidal transformer) than a cheap switch-mode one, whereas the pros of a quality switch-mode PSU usually outweighs the cons (potential high frequency noise) nowadays. Ps. A switch-mode PSU also has a transformer, just a different type and in a different configuration (and purpose). 😉

[@VertexEffectsInc]

TL072 can be used to make a buffer, sure - just not a neutral one. Even TI will tell you they can't run a TL0 below 1K without issues. I see guys trying to run TL072 close to zero, but still will not be able to drive long lines - TL0 series has very poor current output and has stability problems driving output capacitance. Again, TI states that normal use is at least 1000 ohms (1K) series output to keep stable under. Also, the input biasing is very poor. You're going to get color, distortion, etc. with a TL0 and that's not what you want for a buffer. Buffers aren't and shouldn't be distortion generators.

[@VertexEffectsInc]

In our field, with the quality of switch mode power supplies, and the size of them, there is no reason to use a linear supply any longer. The question is not which is better on an infinite spectrum, but rather what's the best solution given our application and what's actually available (there really aren't any REAL true "toroid" supplies out there for the most part - or very few). Remember, our field has few, if any, standards, pedals are spec'd and the maker's discretion. A real "wild west". Designing products like a power supply is all about engineering compromises, and I think most notably, the litmus test is "what's in the audio range". If you can filter accordingly so any noise is well about what the human ear can detect that you're pretty safe and they've been using this for years on the Pro Audio side even though we're just adopting it now in guitar pedals and accessories. I think the false premise here is about the presumption of application and use on a pedalboard and the quality of a high end linear supply in other industries as being equal in the pedal industry. In our field, with our application for pedals there are far more issues with linear supplies than with switch mode supplies of equal quality. Namely because, 1) getting a linear supply to produce the same voltage options and current options as switch mode for today's pedals - you're looking at a supply twice as big and twice as heavy (at least) than its switch mode equivalent. 2) most of the larger supplies that can get close to what the higher end switch mode supplies provide (in terms of V and mA) are aluminum so they can use the chassis as a heat sink - this means no more electromagnetic shielding. Magnetic leakage is now an issue and you're going to have sensitivities to pedals in proximity to the supplies. This is further problematic because these higher current pedals draw so much that you're most of the linear supplies I see come through here are almost pulling max current which means the magnetic field is as exaggerated as it can be - typically resulting in more noise issues. And again many of these "Semi-Toroid" (mostly C core or R core) supplies don't have mumetal or steel caps on them, so not much protection there. Easy to test this with a single coil pickup wired to a 1/4" jack - I do this all the time when I used to work with more linear supplies to see exactly where there were "problem areas". 3) Linear supplies are impractical for bands that travel - you're either switching supplies for every voltage of each country or using transformers - not that practical for those on lower touring budgets that have to resolve this on their own without a road crew or tour manager.

[@benstolt]

As far as power supplies go, Maybe I could have made myself clearer. I’m not at all arguing the legitimate use of switch mode supplies, and their clear benefits in pedalboard applications. My comment was perhaps more intended for any curious readers wanting to know why they are becoming standard practice in this application. (“Cheap” switch mode supplies, in my book, are wall warts and similar, not the products mentioned in the video). As you say, it’s not about what’s best on an infinite spectrum, but most suitable for the application at hand. And in this particular case, a no brainer. // About buffers - not sure what you are referring to in terms of Ti specifications, but I’m curious as to how one of the most common standard op-amps for this very application allegedly is terrible and how you arrived at this conclusion. I’ve built loads of designs in the buffer/line driver realm with TL072 without any of the issues you describe. What annoys me about pedal manufacturers (and the boutique scene in particular) is the constant nag about color/transparency, and the inherit misdirection it presents. Most things generally appreciated are all but transparent, but that’s the whole point. The same way Hendrix’s long coiled cables played a crucial role in warming up a strat hitting cranked plexis, people opt for what sounds good, not what’s technically transparent. Passing any overdrive off as transparent is like describing beer as a clear liquid, but that’s a whole different discussion. My point being that saying “the klon buffer is not such a good buffer” is at best highly subjective. And that the TL072 chip is bad for buffers is just blatantly wrong. You might like the possibly slightly warmer sound of a FET or transistor based approach (like the Cornish buffer for example), even though it’s technically less transparent. That’s all good, but it’s still an opinion and not a fact.

[@VertexEffectsInc]

@@benstolt I think you were clear on this, I was just solidifying that in practice with the gear in question - switch mode now supersedes what a linear supply can equal at the size and price point. I think we're in agreement on this. I reference the TI specs because it provides a baseline for the optimal conditions for the OPA. I mention 1K a one of the critical specs as the TL072 OPA isn't stable below that (by TI's own admission) and 1K is already a poor output Z for a buffer that's intended to drive any amount of capacitance on the output without any change in tone. Sure, a buffer could be made from a TL072, just not one that will accurately represent the sound of your guitar plugged into your amplifier with a 10ft. cable as the baseline "reference" when driving 10+ pedals, all the patch cable interconnections (presuming for now they're all in bypass and true bypass), circuitry inside the pedals from the I/O's to the footswtich, and a 20ft output cable bringing the pedalboard back to the amp input (a standard pedalboard). I'm not excluding the possibly that someone could decide to use a TL072 for a buffer, it would just be a the wrong part for the job if the goal is to be as colorless as possible. I think your point about the boutique pedal industry has merit. I would say where we diverge here is that typically these terms in aggregate are attributed to characteristics of "distortion" colors or lack there of. This conversation is not typically associated with buffers as so few companies actually make dedicated buffers, and even fewer make great ones (or even good ones). I also think there is a lot of "broad brush" painting of buffers - with the narrative reading something like "as long as you have a buffer you're fine" not differentiating for the quality or efficacy of the buffer itself. It would be like saying "you don't need a Klon as long as you have an overdrive" as though all overdrives are the same. It reads to me like where you're going at this from more of a taste profile ideology, i.e. "do I like the sound that Buffer X imparts?" Of course that is subjective - but not what I'm talking about here. In particular, I'm looking at what we can reasonably qualify as a high quality buffer based on the specifications and what we can test as amateur guitar players without much if any instrumentation. The baseline I talk about often here is putting your rig in a true bypass looper and brining it in/out so you can test how close your tone and dynamics are running through a pedalboard versus directly with a 10ft. cable into the amp for example. To me, that's the litmus test. I like the sound of my amp, I want as close to that sound as possible when running through my pedalboard, so my testing procedures and reference point reflects that. A TL072 versus a superior OPA for a buffer that's linear (BB2134 perhaps) will more more accurately represent what came in on the input even after a slew of pedals can cables. You may prefer a TL072 sonically, but it won't be as colorless as a more neutral OPA choice, and I would guess at that point that you prefer your amp with some additional color beyond what it produces normally if the TL072 is your preference. With the Hendrix example, this is a compensation - perhaps informed by preference but also potentially by limitations of the time and lack of people to properly modify his amplifiers to his liking so he's adding a bunch of capacitance after his pickups before hitting any pedals which were all pretty high Z. It's hard to say if he would've done it different had he made music for more than a handful of years before his untimely death. This set up wasn't unique to Hendrix, we see most guitar players of his genre and generation doing much of the same with long coil cables into multiple loud 100W amps, maybe a few pedals. Most of them that are still around have evolved out that set up decades ago for reasons we can mostly only speculate. The Klon buffer isn't a great buffer if you're measurement is how well it represents the input signal on the output when it's driving say a 50 foot cable with 40pf/ft. (Mogami 2524 type cable let's say) compared to a high quality buffer - like the Mesa Boogie High Wire for example. I've done these tests ad nauseam and it's no magic trick to see what these style buffers impart to the sound. Remember most pedal builders aren't rig builders, their not typically representing the conditions that most of their pedals will be used it with 5+ pedals preceding them, and 5+ pedals following them - all mixed impedances in/out, all different buffers from OPA, JFET, BJT, etc. Most pedal builders are optimizing for their own test conditions, typically in a vacuum, without much consideration of the above. I prefer OPA buffers over all else, they're generally the most neutral, but there is "more than one way to skin a cat" - but choosing the right part for the job is critical, and I'd never choose a TL072 for a buffer - again buffers shouldn't be an EQ, and most certainly not distortion generators which they become the more capacitance that is added on the output of a poorly designed buffer or a buffer insufficiently designed to be a high quality line driver. The Cornish buffer is BJT as I recall and does some unique stuff with the feedback loop to to get the input impedance up instead of going the Boss route of using a FET input so you can get that 1M input Z and then the BJT on the output for the lower output Z. I know many like Cornish's buffer, however it's not neutral by a mile and has a color of its own for sure. Some may like what it does to the signal, but it's not the same as the guitar into the amplifier with a lot of capacitance on the output. So again, by my standard of guitar into amp with a 10ft cable as the reference tone - the Cornish buffer doesn't resemble that sound when you but a pedalboard after it and lots of cable capacitance.

[@benstolt]

I hear you. I just don’t agree with you. No, TL072 won’t have stability issues in a buffer circuit with lower output impedance than 1k. Sure, op-amps in general can become unstable driving a capacitive load, commonly solved with a series resistor in the capacitor-resistor junction on the output. Still not sure what you base this argument on, it sure isn’t the data sheet. But you do you, I rest my case.

[@VertexEffectsInc]

Luckily, that's the only supply they make that actually uses steel as the chassis and does provide some shielding. You may not be experiencing noise now...so you can test that and see. Also the EMF increases the more power you draw against the power supply...the more current drawn against the supply the larger the field. Mumetal or steel would be the ordinary way to do this, but it's not as easy as just throwing sheets of metal between the supply - you have to ID where the field is and try to encase it as much as possible.

[@DonaldVanHall]

I like the idea of debunking myths but YOU ARE COMPLETELY WRONG about Switch mode and Linear power supplies. Switch mode supplies are fundamentally noisier than linear power supplies because they are switching during the regulation process at frequencies between 100Khz-1MHz. This switching noise, its harmonics and subharmonics, can be reduced but it is costly to add the supression components. Linear supplies do not switch their input voltage to regulate their output, thus they do not generate switching noise. Additionally if they have a gapless toroidal transformer a linear supply will generate less field than a cut core transformer. Simple circuit layout and a metal box will be sufficient to shield the 60Hz field noise of a linear supply transformer. With the high frequencies generated in a switching supply the enclosure needs to be continuous at the seams and the ac input and dc outputs need supression at the switching frequencies. So why are switching supplies popular? COST and efficiency, In consumer electronics price of manufacture and sale is most important to maximize profit. That being said I DO AGREE that solderless cables are much less desirable than soldered so i do appreciate your info on those.

[@miitchmitchell]

I'm sure you're right but after watching this, I replaced my voodoo labs power supply with the Strymon Zuma and my noisy cramped pedal board became quiet

[@VertexEffectsInc]

Donald, if you're looking at two supplies in our field - guitar based products and accessories - that have equal number of outputs, voltage ranges, and current output that are the best examples in their respective classes of switch mode and linear, then the linear will NOT be superior, in particular, if you're looking at what shows up in the audio range. I think many critics here of switch mode supplies are taking poor examples of these style supplies and putting them up against a gold standard linear powers supply - that's an easy straw man to knock down. If you put a Strymon Zuma ($249.99) against a Pedal Power Mondo ($279.99) it's pretty easy to see why you'd want to go with a switch mode supply practically. The Zuma less than one-third of the size, has more voltage options, more current per output, can work in any country in the world, and can be placed anywhere on the pedalboard without consequence of noise or risk of the magnetic field interfering with your pedals with ZERO noise in the audio range from the supply. The Mondo, by contrast, has no consequential electromagnetic shielding - fully aluminum chassis (which most linear supplies have that are putting out as much current and voltage options as the Mondo because they use the chassis as a heatsink). As a result, this supply causes noise if you get your pedals too close to it (or even your patch leads), or dare I say, put it under your pedalboard like most DIY folks do on a Pedaltrain or similar style board. You've put your pedals in the path of the magnetic field and the more current you draw against the supply the more intensified the field becomes. Now you can place the Mondo on a board in a way where it's going to be objectively equal in performance to the Zuma without any noise risk in an equal environmental condition. However, it will command more space, a larger pedalboard if you're using the same number of effects on a rig as you would with a Zuma as your PSU. Your routing and pedal placement will also have to consider the magnetic field - again needing more space on the board to distance the supply from the pedals. Coming full circle to the practicality stand point, I don't see how this is advantageous to someone building a rig in 2021 with a choice between these two supplies all things being equal. The biggest thing that I think you're discounting here about linear supplies (along with some other critics here in the comments section) is you underestimate the magnetic field leakage and the fact that most of these linear supplies aren't actually toroidal transformers even though they say they are, and as a result don't have the same benefits. A true toroid has to have these qualities: a round, not oval, magnetic core and even that isn't enough. It has to have equal winds fully (360 degrees) around this magnetic core or it "leaks" magnetic field. Also, any hold down material down the center can cause spurious leakage. If the center hold down bolt is magnetic material, it has to be perfectly centered or will cause issues. Non-magnetic stainless steel (not all stainless steel is non-magnetic by the way, there are many different stainless steel grades) - even then, a toroid leaks, it just does so in a controlled manner and at a low level on axis of the hole where a steel chassis or steel can control it. The advantage is the horizontal magnetic filed is null, so sensitive electronics on that plane will not see any magnetic field. I have seen it done wrong with some major manufacturers power supplies that actually defeats the expensive toroid altogether.

[@VertexEffectsInc]

Are you sure there wasn't a distinction between AC and DC? Typically, the rule of thumb, when mixing audio signal with DC, is there no problem at all with the currents and low voltages of guitar pedals. However, sometimes I will separate them to make easier trouble shooting if I ever need to re-work the power or audio without having to undo an entire loom of cables. With AC however, this can be much trickier and if you're going to touch AC and audio cables it's best to do it at 90% or perpendicular to avoid any noise resulting from this intersection.

[@voyantcreative]

@@VertexEffectsInc truthfully your description in said video was a little lacking of direction and hard to discern between different thoughts, so perhaps you meant to make that distinction, as as I said in my above reply you did mention AC vs DC within it, but you very clearly stated that although low voltages arent a huge concern, you should always at least try and separate your audio from your current. Honestly I didnt see an issue with it, its good practice whether it matters or not - but watching this video felt as if you were saying exactly the opposite while also kind of snarking at people who do say you should care about DC and Audio lines.

I've had just as many problems with soldered cables as I have had with solderless cables. In fact, I've been using Lava Cable for a number of years now and if you put it together properly, you'll have little to no problems. But cables are simply a weak link in the chain. If you're dragging your pedalboard to gigs and rehearsals a lot, there's just a chance that a cable will fail and the weakest point will be where the plug attaches to the cable. But that also applies to soldered cables. The only brand I've had excessive problems with is George L. And I also think that's the brand that gave solderless cables a bad name. Once I switched to Lava Cable, I actually had almost no problems anymore. Difficult to put together. But if it's done right, it's just as strong as a soldered cable. Guaranteed. People should not immediately write something off on a single experience. That is also very inherent to the guitarist world. This is how myths arise and happen again here.

If you’re touring festivals, playing outdoors in humid environments, or just have bad climate control where your board is stored, using solderless connections is an unnecessary risk to take. Your anecdote should not be taken as fact. You may experience “almost no problems anymore”, but that doesn’t mean your solution is just as good. People don’t want to feel dumb about their purchases. I understand the urge to justify the way you spent your hard-earned money. I don’t think you’re stupid for buying a product that works for you, and is simpler to put together than the alternative. But if you’re a musician traveling for work and performing in different environments every night, especially outdoors, you could save yourself a headache by using more reliable techniques.

It is also much easier to repair a patch cable. Try that with a soldered patch cable and plug. The guy from GigRig also uses Lava Cable as far as I know.

Hey Mason very good video! Your comment on the myth of DC cables running next audio cables, the answer is it depends. Especially with switch mode power supplies. Often times the output stages are not properly filtered and they have switch mode frequency noise on the DC lines. Usually from a cost cutting measure by the manufacturer they leave out components like inductors capacitors and resistors designed to suppress that noise. Those inferior power supplies in that situation would not be a good power supply first off and two running audio lines next to those DC lines that are not filtered will induce noise on the audio lines. So I can understand why many builders don't trust DC power lines.

[@VertexEffectsInc]

If you're using a DC power supply that's designed for audio, you won't have this issue and if you do, it's no related to the proximity of low voltage low current cables but the supply itself and the switching noise relative to what it's connected to.

[@Bassguitarist1985]

@@VertexEffectsInc 100% agreed! I beta test for Caline Technologies in China. They have a new switchmode psu, and in my testing had to change out a load resistor value, but found the resistor/cap values that makeup the snubber network (components to filter out the switching frequency on the DC lines) were adequate. Its cool to learn about this stuff...including buffers! :-P

As always, Great video for us novices. How can you tell if a power supply is Switch Mode or Linear ? I currently have a Rockboard ISO Powerblock V10 Isolated Power Supply.

[@VertexEffectsInc]

An easy way to tell is if it's only designed for one input voltage, e.g. 120V only! or 220V only! Or they'll have a slider or rocker switch to switch the input voltages to match the country. That's usually a sign that it's linear. Switch mode supplies will take any wall voltage on the input.

[@kma6881]

A lot of this video comes across as the sales tactic of making you think what you have is inadequate and casting doubt on the quality of what is common. To be fair, I’m not accusing you of committing any type of fraud. The first two had the tone of “your connections are going to fail” and “your buffer is not good enough.” Your content is usually good. This just comes across a bit like a sales video.

What type of power supply is the new Ernie Ball Volt? I can't seem to find the answer on their website or in the downloadable manual

It looks to be switch mode with the AC mains outside of it. Similar products are the Voodoo Lab x4 and Cioks 4

I always look up whether or not a pedal can run at 18v, and I've noticed that comparatively few do! So, I don't attempt to run any "9v only" pedals at 18v.

@@VertexEffectsInc I believe the Seymour Duncan Diamondhead is the only pedal I have that's safe to run at 18v.

Thanks, Mason. Helpful debunking. Hey, can you name a few favorite single function buffers that you like for starting and ending a pro signal chain?

See the description, all listed and linked there :)

[@chipsterb4946]

Hoping Mason won’t be offended, I just finished shopping for buffers that meet his specs of 1 Meg input impedance and 100 ohm or less output impedance. TC Electronics Bona Fide Buffer, JHS Little Black Buffer, and TrueTone Pure Tone Buffer all meet his specs and are made by companies I trust. The TC buffer is on sale right now at Sweetwater. The TrueTone unit seems to be available only directly from them (it’s listed under “custom shop”) and list price is the same as TC sale price. No switches, no loops, just tiny boxes to tuck underneath.

[@kendogthunder]

Dude, I understood exactly zero of what you said. Thats on me. Lol

[@mitchellchurch3385]

If I am using a Boss ES8, would I turn off all initial buffers in the unit, and use a Mesa Buffer for I/O buffering?? Also I’m using fuzzes and I’ve heard that they are not compatible with buffers? With a system like the Boss ES8 would it be more ideal to just use an output buffer??

[@VertexEffectsInc]

Yes, in a second! Yes, put fuzzes before your buffers generally. Some fuzzes do OK with low impedance, most do not however.

[@aaroncarothers4371]

Your claim about solderless cables has a significant, misleading issue in your video. Full disclosure...I have one board with Lava Cable Tightrope/Solderless ends (22 cables) and one board with soldered Mogami/HOSA pancake connectors (16 cables) which I have made. There are going to faulty connections with both when you are new to putting them together. After I found out how to do both correctly I have not had a bad connection in years...and I am not a road musician but one that plays gigs 35-45 times year and have not had a problem with either pedalboard. I did have more connection issues/mistakes with the solderless ends in the beginning but was able to improve my assembly technique and have avoided these problems. You're opinions on solderless are potentially good ones but when you are saying things like, "You almost see zero of the rig building professional community using solderless cables...", you should actually say who and their words instead of showing shots of named individuals in the industry. They are not saying they agree with you in your video. You mention that you like to see proof but you speak without it when you make a claim like this. Plus, that strength test was ridiculous. 25 lbs. is a great strength level for a patch cable. And let's be honest here, one of the most popular gear KZbin channels in That Pedal Show and Dan Steinhardt are very comfortable in using solderless for world-class professional pedalboards. He has clamed that he has not had one come apart on a professionally made, significantly road-used board...but this is only be one professional example. I am not trying to prove you wrong but do think you are being misleading. I like both...I don't need one over the other as I like soldering cables but the solderless are great ,too. I don't normally comment on KZbin videos but I don't like seeing claims being made with misleading evidence and even more so when it seems you are trying to insinuate that popular gear companies are on your opinion's 'side' without actually validating it. I like your channel and some of the DIY tips you've shared. This whole comment is really a suggestion that you do a better job of backing up your claims as you have made this one frequently.

[@VertexEffectsInc]

Aaron, that video exists, several in fact where I read statements from (some directly to me or from interviews) or do actual interviews with the top rig building professionals. Guys like Robert Bradshaw, Pete Cornish, Paul Rivera, John Suhr, Dave Friedman, Steen Skrydstrup, Paul Lenders. If that's not the canonized list of the best rig builders in the world, I don't know who else should be there. They do say in their statements that they don't use nor recommend solderless cables. The proof of solderless cables not being a gas tight connection is inherent in the connection itself. We're not using cold welding crimps to create a solderless bond in our industry using $5,000 crimping tools that require a calibration every 500 crimps. We're using a set screw that 1/10 the diameter of the center conductor or a threaded connector that taps soft metal (copper) to create a connection while the shield floats and the entire return path is exposed. The proof is in plain site - how can a floated shield be gas tight? It's as if there is a disconnect between physical science and our preference to use one cable over another. 25 pounds is great if the cable is sedentary, but do you know how much inertia is generated by the human leg at normal walking speed with a 160 lbs man at a normal pace? Way more than 25 lbs. I like Daniel, and I think he and Mick do a huge service to guitarists everywhere. That can be true, and he can be wrong about solderless cables. He's actually chimed in comments sections in some videos and said that he agrees that a soldered connection is superior but has found solderless to work for his applications. Very well...but that makes him the exception, not the rule. Finding one guy out of 8 that use solderless that are known rig builders isn't a great testimony for solderless being the professional standard. It's not. I think if you do a little research (or just watch some of our older videos) you'll see that what I'm stating isn't being pulled out of thin air. The facts regarding gas tight connections, the efficacy of solderless connections, and that anyone purporting to use solderless as a pro rig builder is an outlier - with virtually no agreement among the rig building community among legacy builders that pre-exist me or Daniel.

[@aaroncarothers4371]

@@VertexEffectsInc I appreciate the response. My point wasn't that solderless cables are better than soldered which seams to be the theme of your comment. My point was that you did a poor job or trying to relay proof abut your claim. Viewers shouldn't need to do their own when the maker of said video makes a claim. I don't know if the gentlemen you mentioned agree with you but I don't believe they do simply from this video. Provide proof for viewers in the moment of the comment if you are as vocal and repetitious about your opinion. Be the dagger in the heart of solderless cables if that's your aim...but do it effectively. And if a pedalboard is in some situation where you put 25lbs of pressure on a connector then, yeah, use soldered simply for that issue. I don't think that's a good enough reason to only use soldered cables as it seems to be relating to an unusual situation. I am not in Radiohead playing 2-300 shows a tour all over the world. Most of the people watching your videos are probably not touring musicians and have fun with their gear at home or playing out a bit. Again, I am not saying one type is better than the other in this comment but after learning how to assemble the solderless cables properly I have not had a failure in the 2-3 years I've used them on a board which was been used for close to 100 gigs with all the loading and unloading of gear, beer spills (not too many), stomps, kicks, etc...However, in my heart I feel soldered is probably a superior connection but that's not because of your video but rather through common sense. I'm not trying to be a dick here but I work in science and if I tried to support a claim they way your video did I would be ripped apart by my collogues.
