I spent a year on this.
In October 2021 I did my first amp test for this video and I was shocked by the results, leading me to keep chasing the reasons an amp sounds like it does until October 2022 when I finally get to show everyone what I've been working on all this time.
More work went into this than anything else I've ever done. I'm being totally honest when I say I'm just a performer, I don't know anything about circuits. This took me way outside my comfort zone, but I uncovered some truths that I find extremely interesting.
Throughout the process I kept getting results that didn't match things I had read and heard not just from people on the internet, but from heroes of the industry. It made me realize that we're currently alive in the only time in all of human history where two things can be recorded, edited together, and played back to back, easily, at home. I'm not so sure that our heroes ever did that. I'm thankful that I have the opportunity to.
The way I look at guitar amps has been changed forever.

[@greyklopstock7155]

Although I consider myself a musician at heart, I actually have a really close relationship with science and the method. I took biomedical science courses all through high school, I took courses in physics, acoustics (which is really just the physics of waves and sound), and eventually majored in psychology. So my educational background is much more scientific than artistic. As a result, when making choices for my signal chain, recording equipment, plugins, etc, I've always used what I feel is a very scientific mindset and philosophy. So I LOVE stuff like this content from Jim. Like, I use amp simulation exclusively for guitar, as while some might not consider it "authentic," it gets me what I feel is at least an 80% similarity to in the tonal qualities of the audio as the real tube amp and cab while being infinitely more consistent performance wise. I don't have to worry about the age of the tubes, warming the amp up, the temperature, the room, how broken in the speaker in the cab is, the mic, the mic pres, etc. I KNOW what I'm getting out of the sim every single time. I don't really worry about special diodes, or "magic 9v batteries," secret mojo enhancers, anything that can't be defined practically and precisely. Like, I don't look for "warmth," I look at the qualities of the saturation and how the EQ curve changes with saturation. Saturation is just a type of compression, which can be quantified. EQ can be measured. And if I know the EQ, headroom, and saturation qualities of different types of circuits and amps, I can make decisions based on known quantities more or less instead of just the arbitrary qualifiers ascribed by fellow musicians or sales people. I've had working musicians and recreationists alike sometimes look at my approach in half amazement half horror. It's a lot of work, but doing stuff like listing current draw for different pedals, comparing the differences in the knee, attack, and release curves of different compressors, the behaviors of different EQ bands on well known gear, all of it I feel demystifies and removes bias from my decisions. And to me, I feel like learning that kind of approach is what makes science so important to teach in schools. Believing the earth is flat or that phrenology is a credible discipline probably won't kill you. But learning the scientific method, learning what it means to identify and control for variables, all of that stuff is SO IMPORTANT. Because if you know how to do that, you can make informed and reliable decisions based on provable and quantifiable dimensions rather than off of essentially dumb luck. L Sorry for such a long and random comment, I just think it's really cool to see other musicians than myself be passionate about science and not be afraid to approach their art with a clinical and scientific mindset

🤔 This video has opened a whole new can of worms for me! I found this video very informative, and it destroyed some of the ages-old notions about what 'really' influences guitar sound. But, I am baffled when it comes to the sound quality of his Telecaster. I found it to be uncharacteristically lousy, and off-putting for a higher end Fender guitar. It sounded that way pretty much regardless of what he plugged it into when making this video. I've heard plenty of guitars of all makes that sound good through a clean signal, or with relatively minor effects, but ^this particular Tele definitely wasn't one of them. That brings up the next obvious question, why does one allegedly higher quality guitar sound significantly less appealing than others of the same alleged quality(or even lower quality). Are the components on his guitar so different than the average Fender?

[@castleanthrax1833]

Me too, but I'm just a performer, and know nothing about circuits.

[@edsonbrusque]

I'm an electrical engineer who played guitar for something like 35 years. I entered this same rabbit hole in about 2005. I even started a very small amplifier manufacturing company. My undergraduate final project was about the tone stack. This whole video gave me an amazing feeling. You seem to be replicating all the things I've been saying for 15 years and nobody want to listen. Yes, the "types" of circuits have some influence but they are minimal. It's about the entire design but specially the tone stack and speakers/cabinets. It was also fun to see you using LTSpice. I've done countless simulations with it and (when I did it right) got very close results to the real world stuff. Bravo. You're a legend. EDIT: Real world potentiometers are very unprecise. In my undergraduate thesis I had to find double potentiometers that where reasonably matched to do my comparisons. A lot of difference between amps of the same batch may come from this lack of consistency. This also could make the 3 o'clock position of a specific knob on an specific amplifier have very different value from the 3 o'clock position knob of a "clone" or simulation.

[@GerSHAK]

+

[@merwinjm]

I've seen some similar conclusions about pickups and "tone" caps. The accuate value varies from brand to brand and model to model and if you were to get the same resistance/inductance of a pickup and the same resistance of the pot and capacitance of tone cap, a cheap setup could sound just like or as good as the holy grail set.

[@jamiemascola6614]

Same boat, consulting engineer and long time guitar player. I design and build tube amps as a side business. And I agree that the vast majority of the amp's tonal character is in the circuit topology (number of gain/dropping stages), the cathode networks, coupling caps, the tone stack, and the power amp class. The tube type, voltages, cap types, resistor materials, etc all contribute. But they are like frosting decorations on the cake. A speaker change has about the greatest sonic impact of any amp component.

[@edsonbrusque]

@@merwinjm Yep. I've made some tests in that regards. For capacitors, the two most important electrical parameters are the actual capacitance and the ESR (Equivalent Series Resistance). There are other things (like inductance and parallel resistance) that you must consider when doing high frequency or high power stuff, but this isn't much important when we're talking about a guitar tone cap wired in series with a potentiometer. What really matter here are that two values: ESR and actual capacitance. Old paper oil capacitors have loose tolerances and high (comparing with a modern capacitor) ESR. Measuring the capacitance and the ESR of a vintage capacitor, I could mimic the exact behavior using two cheap ceramic capacitors in parallel (so I could get very close to the actual capacitance) and a cheap resistor in series with the capacitors. The noticeable difference in sound between a modern ceramic or polyester and a paper oil happens when you close completely the tone potentiometer. In the case of the modern capacitor, the total resistance in series with the capacitor (ESR + Potentiometer) go very close to zero (because the ESR is low). In the case of the vintage capacitor, the total resistance in series with the capacitor (ESR + Potentiometer) is in the order of tens of ohms. Sometimes more than 100 ohms. This means a little less high frequencies filtering. Want the sound/feeling of a vintage cap with a cheap modern ceramic? Just don't turn the tone knob all the way down. Or just put a cheap 100 ohms resistor in series. Done.

[@edsonbrusque]

@@jamiemascola6614 Yes. I just would make an observation about the power amp class. Well designed Class A, Class B and Class AB amps have practically identical behavior when not being overdriven. But: 1) Single ended vs push-pull have different harmonic contents across the entire range. It's subtle, but it's there. 2) The amount of negative feedback does make the circuit more linear, so it tends to cancel that harmonics added by the phase splitter and the power amp stages. This is why the power stages of an old single end (with no negative feedback and no phase splitter), a push-pull without negative feedback (like a VOX AC-30) and a push-pull with lots of negative feedback (like a Fender Twin Reverb) sound a little different, specially when overdriven. The power supply also could have some role here, as the voltage tends to sag when more current are pulled from it. This is why solid state rectifiers with a well designed and tough transformer sounds tighter and a tube state rectifier (that have a relatively high ESR) sounds looser with a sort of compression. About the classes, usually the same amp when working in low volume could be in Class A, in medium volume in Class AB and when being overdriven, Class B or even Class C (when you will have crossover distortion). To design a good amp you do have a lot of things to worry about. But in the end, to the user, two well designed power amps would sound very similar. This tech talk could go on forever. LOL

[@LilBoyHexley]

This seems like what I would expect. Coming from the audiophile world my expectation is that assuming there's nothing flawed with a given electrical component, and it's doing its job "correctly", it really shouldn't be coloring the output signal in any notable way over a comparably functioning component. The things that do actually effect and color the signal are the parts that are explicitly meant to be manipulating the signal in concert with eachother. At the start of the video my gut instinct was "amps are different because their knobs/signal manipulation chain (tone stack, though I didn't know what it was called) are different". Amps have a lot of active signal manipulation going on, so it makes sense that two amps would be different outside of the particular points where you can get their output curves to line up. And that a lot of the "signature tone" an amp is known for comes from the active efforts of engineers to give the amp that particular sound via signal manipulation, and not some special quality of the electrical components they selected. Which is just marketing. These seems like the same story as the cab video. A lot of stuff effects the sound, just it's not some inherent quality of the components, but the active choices being made in the cabs assembly that effect the intended sound in the end.

For a short time (before hurricane Katrina ruined it) I played through a clean Bogen PA amp, the kind a store uses for “attention Kmart shoppers!” I had an old school Line 6 Pod and a 12 inch speaker all connected and mounted in a storage trunk turned on its side, fitted with wheels. I could roll up, open the door, pull out the Pod on a tray, plug in, and I was ready to play. I could get any tone I wanted with all the volume I needed. It weighed about 30 pounds. But it all got washed away, and I got old. Fun times.

Throw each sound sample in a spectrum analyzer and you can note that the vast majority are visibly different but you can only tell using some software and some technical know how. I can personally vouch for this because I did exactly that, and a friend and I replicated some of these experiments though to notbthe same extreme and we arent luthiers or wood workers but we did try some using the same partscaster. The only misstep that I saw him take throughout this series of videos is the difference between having brass saddles and a brass nut as opposed to steel. I can close my eyes and pick the guitar thats brassed out from the ones with steel out of a line up, subtle as it may be, I was surprised that he didn't hear it. Maybe it's because I was listening in very expensive studio monitors 😆. Unnecessary for the level of studio I have but it's like buying a gold jet ski with spinning rims. Why? Because you can I guess. Haha. I like having true stereo and a center speaker. I run my TV audio through a compressor so the volume is consistent when there is dialog, action, quiet parts, etc. Commercials are not louder than the show and vice versa. I should make a video on how I managed that. I have 3 computers here with a central server and I do dork stuff. Obviously. Lol

[@davidfuller581]

Hey, amp tech here. You're absolutely on the right track. Most of what we hear is frequency response, so it stands to reason that cathode bypass cap values, coupling cap values, and interstage and tonestack filter choices - all of which affect frequency response - will dictate a huge amount of what an amp sounds like. Tubes are quite a bit more subtle and arguably make little difference within a type. However you can tell EL84s break up a lot earlier than 6V6s, despite being the same nominal power output (a pair will do roughly 12-15 watts at about 5% THD). That's because EL84s are _insanely_ high transconductance (a measure of how much current from cathode to plate changes when the input voltage on the grid changes by a set amount, appropriately measured using the mho, which is just ohm backwards) compared to 6V6s. For a given input voltage, the EL84s are going to be a lot closer to their linear power limit than 6V6s. And of course, very few amp designers compensate for this in their amps, so EL84s sound squishy because they're probably quite a bit more distorted than a 6V6 in the same amp. The same holds true for their larger cousins, the EL34 and 6L6. But it's more complicated than that. Amps with lots of negative feedback (think of it as distortion reduction through clever use of phase cancellation) will have less distortion, but the _onset_ of that distortion will be much more sudden. Think solid state, where it's clean clean clean CRACKLE - that's the result of lots of negative feedback. Black panel and silverface Fenders are the same way, the design philosophy was lots and lots of clean output power. Little or no negative feedback means a sooner, but more gradual onset of distortion - think about how a 5E3 Deluxe seems to change so much depending on how you pick, even though you haven't even touched the volume control. As for rectifiers... Overrated difference. However, the same amp using solid state or tube will operate at pretty different voltages. Tube rectifiers have a pretty high internal resistance and drop a lot of voltage across them - anywhere from about 15 volts for a GZ34 to up to around 60 volts for a 5Y3 - where a silicon diode has barely any internal resistance and will drop about 0.7V across it. So, the same amp with the same power transformer and the same high voltage secondary will be substantially different operating voltages. I measured this on a Mesa Rectifier once - Silicon diodes were about 470V, tubes were about 415. With the same bias voltage, that's a pretty damn different idle current flow in the power tubes, so you'll get substantially less power output from the tube rectifier mode.

[@scotlandish4718]

Your comment, though probably incredibly informative, is Chinese to me... I justa plucka da strings.

[@williampimblott8373]

Agreed. Speakers/box are huge, cathode bypass is huge. Sag as it's referred is more of a feel than sound. You're not gonna get it with a looper I feel. I also feel like the subtle difference you'd get between various circuits especially SS/tube changes drastically when you open them up wide all they way. Getting a good sound for a mic, vs getting that same sound but loud enough to sit in the natural mix over a heavy handed drummer. Jim has a point though. At the end of the day.

[@user-ge2vc3rl1n]

In a studio environment you can go so far in shaping the sound of your amplifier in post production, it's actually amazing. When that power was brought to modellers, there really are now no limits to how you can shape your tone.

[@philosyche]

[@Nicoya]

Hey Jim, great video. Just wanted to touch on one or two points: The whole "solid state distortion sounds like garbage" is actually based on early transistorized amps that had crossover distortion due to the amplifier class (you can make a tube amp that sounds equally awful, but people are smart enough not to), and/or due to clipping distortion from BJT transistors, which have a different distortion profile than tubes do. In modern solid state amps (or distortion pedals), the crossover distortion is eliminated through using better amplifier classes, and they use JFET transistors in the distortion stages which have essentially the same distortion profile as tubes. There's also a subtle type of distortion that you missed in your test protocol. With tube rectifiers and amplifiers, you can run into a phenomenon known as space charge depletion. This is where the electron cloud around the cathode gets drawn away by high anode currents. If you have a tube PA amp that's playing both drums and guitar, let's say, and the drummer plays a really hard hit while the guitar is wailing away, the momentary impulse of amplifying the drum hit will cause space charge depletion and temporarily reduce the available anode current for amplifying the guitar sounds. The end result is a short ducking effect in the amplified audio immediately after the drum hit. This phenomenon is worth mentioning because it does not occur in solid state devices, though you can simulate the effect fairly easily by adding a few extra passive components. Anyway, the reason that all this amplifier snake oil still exists is because the people who know better (the EEs designing the amps) have a vested financial interest in perpetuating the mythology. If everyone realized that you could throw $20 of transistors and passives into a box, shake it around, and pour pure sweet tone out into the speakers, a lot of companies would make a lot less money.

Fantastic work man. I launched a career and reasonably successful company based on a similar understanding when modeling analog studio gear (eq's, compressors etc.). Inside all of that expensive gear, there is distortion, there is eq, and there are transfer functions... and that's it. The difference between a 'warm, pillowy' old LA-2a tube limiter and a 'bright, snappy' modern SSL compressor is nothing more than the number, order, shape, and degree of those three processes. That doesn't make modeling easy --- it's often impossible to get things sufficitently emulated in a world where a 1% difference in sound can mean everything to the operator --- but it does make it simpler when you understand the variables and how to parse out their individual contributions.

What this tells me is that finding the right amp is like finding the right guitar. 99% of it is how easily can you get to a tone you love? That’s why it works to use the same gear as your music heroes. You already love their tone, and it’s easier to get a similar tone with similar gear. It’s not because it’s inherently superior. Man this entire series is so freaking awesome. Jim, please keep doing this.

[@void_snw]

Definitely agree. Clones, small amps, "based on".. becomes a lot more meaningful when you know just how close you can get without having the actual gear. In the end it comes down to how comfortable is the guitar and do you like the looks of it, have roughly the right sounding pickups in it, have an amp based on the circuit you like most, and choose the right speaker! Nobody needs multiple thousands worth of gear just to love the tone of it.

About 25 years ago, I was in a bar where a three-piece band were starting to set up. They were (to me then) old guys - in fact about the age I am now - and I paid only scant attention. They were set up inside 10 minutes, and started to play. They were brilliant: hard hitting and energetic. The guitar player had a telecaster of some sort and a superb tone, and wrung the neck of the thing. I went to talk to them after the show, to see how the guitar player got that tone. I found he had a Korean Telecaster worth about $150 new, absolutely bone-stock. So, was it a boutique amp producing that fabulous thick tone? Nah, it was a 30w Sessionette (a British all-transistor combo from the early 80s). To cap it all, he also had a deformed thumb on his left hand, permanently curled over so he had to play with the thumbnail against the back of the neck. It’s what you play, how you play it... and the gear is there mostly to get you in the moment so you can enjoy yourself. If you can do that for a couple hundred bucks, you’ve cracked the code.

[@GCKelloch]

You may notice that the actual tube amps compress a bit and the SS amp does not, but tube amp compression is different than signal level compression. Tube amp compression starts to cancel the note fundamentals in the OT, and maybe in the tubes to varying degree, while generating harmonics. The speaker Z curve also affects the midrange so the bass and treble remain more dynamic when the amp is driven harder. It's why tube amp overdrive sounds more lively, but some SS amp designers have emulated that behavior.

I just watched all of his “Tested” videos and I’m blown away. Literally destroyed everything I thought I knew about electric guitar and amps. 😂 i’m in the market for a new electric guitar and amp, these videos drastically changed how I’m going to approach shopping for them.

well done! The speaker changes way more than Id ever imagine. I was going back and forth between the celestian GB and the alnico blue, and in the same amp they sounded way different.
