@WaylonMcPhersonGuitar where do I connect the ground of the Input jack? Because I use Plastic Jacks not steel ones and use plastic enclosure too

[@allenmitchell09]

This would be cool to do under the pickguard.

[@simonhawker9277]

i prefer the sound of a compression sustainer but very useful thing you got there, in a studio, cool

[@commonsensehill372]

If you wanted to, you could mount this inside a cavity on your guitar and have the knob and perhaps a toggle switch coming through the front. It could work that way if done right.

[@LGPhotoArt]

Nice !! Thanks.

[@ValBoschi-ix9cd]

So different to anything I've come across.... very cool... merci.

[@WaylonMcPhersonGuitar]

Glad you liked it!

[@simonkormendy849]

Essentially, the circuit uses a small-signal transformer to step-up the voltage signal from the guitar's pickups, the signal voltage gets stepped up by the turns-ratio of the transformer, so, say the transformer's turns-ratio is something like 4:1, i.e. 4 secondary turns to every 1 primary turn, so theoretically if we feed-in a 1Vpp signal into the primary we should see a 4Vpp signal on the secondary winding, but transformers are, in general, about 80% efficient, 20% of the signal is lost in the form of heat, we still get an increase in signal-level though.

[@Ma_X64]

There's slightly more complicated processes. Due to impedance changes frequency response changes too. Also phase characteristics moves slightly in different frequencies.

[@ditchgator1]

The passive transformer in my Yamaha Revstar RSS02T is huge in comparison. Very useful tonally with volume control along with a boost.😎👍👍

[@JulioBergo83]

It's a reamp box with buffer. Nice!

Thanks for this video. Your solder joints look perfect, and details about cleaning the screw holes for reliable grounding and details that most folks (like me) would overlook. Good stuff.

[@thomasmozelt585]

very smooth!

[@oddshot60]

LOVE your projects. After 73 years of studiously avoiding electronics, you are turning me into a boffin ... or at least a nerd of sorts. Any chance you could do up a nice lush, yet simple Hawaiian sounding spring reverb for lap steel guitars?

[@anthonyb5279]

I just got a desktop class A tube amp and some reference monitors for my computer. It was super cool to hear the nuance of the different tones you got from that gear.

[@mikejames293]

Please explain. I dont understand? A tube amp for your desktop computer?

[@anthonyb5279]

@@mikejames293 No a small 35 watt tube amp to run desktop speakers. Yes its hooked up to my computer to run reference monitors. The tube amp with a class A circuit reacts faster and has extremely low TIM distortion. It lets you hear the texture of your fingertips against the strings, every little detail in the sound comes threw. Thats the reason to use a tube amp with a class A circuit vs a more dampened class B circuit. A MOS/FET class D circuit can do this too but not a regular solid state transistor amp made of resonant circuits. People say you can't hear the difference but they just have bad ears.

[@mikejames293]

@@anthonyb5279 What does your signal chain look like? Guitar > Audio interface > PC > Audio Interface > Desktop Tube Amp > Speakers ???? Are your speaker the kind without built-in amplification? Can you run headphones on this setup? Have you tried FRFR?

[@anthonyb5279]

@@mikejames293 I made the speakers my self, same components that Mackie uses. No I would not use a tiny transistor consumer level crap amp for anything. I use Apple so I can just go line in if I want to but most of the time I want the sound in the room and my VOX with Greenbacks so usually mike it. I don't care for modeling I have the real gear so why model its not better. I have some 4 Chanel M-boxes I rarely use. But that does not matter why have crap speakers and Amp for any thing. I have and know how to make pro gear so why not. You realize this is common these days I'm not special??? Yes I have headphones but I still use a tube pre amp (made my self). You got to understand I had a Class5 and Class2 FCC license and a Ph.D in Engineering I can an have built TV and radio stations from the ground up. I don't use consumer audio equipment. There are a lot of good desk top tuber amps out there for your computer Pyle makes one for only $50 and it sounds fantastic. Just google small tube amps everyone makes them. Just make sure its an undampened class A circuit if you are using it for a reference monitor. Class D MOS/FET is also good for this.

[@Rob-wg9nz]

You can make a pretty decent JFet buffer with 7-8 components, then you either put it in the pedal (then it's not passive anymore) or make separate a buffer pedal to use if you are running a passive guitar. A Jfet buffer also leaves the frequency response almost intact. A passive guitar cannot drive this pedal because the secondary of the transformer is effectively a small resistance that goes to ground, so since the power generated by the pickup is constant and equal to V_out/R_out^2, if you put a low output resistance since the power has to remain constant (because there is no buffer) the output voltage goes down. So pickups and piezos work well with high output impedances.

[@bluzmansix]

Awesome my friend. I love your thinking behind these. Right let's warm up the soldering iron!

[@Joseph-y6p]

Hey man, this channel is awesome!! Really love these pedal videos! Subbed!

[@mattfleming2287]

Fascinating. So your trading low end, which requires a lot more power, for volume in the upper mods. This may actually solve an issue I’ve had forever. 2 guitar band, I provide the low end, the other guitar is giving definition for the riffs with strong mids. I do the solos which obviously doesn’t work well with a low frequencies.This may be just the thing!

[@WaylonMcPhersonGuitar]

Cool, That could definitely be the ticket!

[@Bleats_Sinodai2]

you could easily add it in the guitar as well, just build a simple op-amp buffer and put the transformer in front of it, then change one of your pots for a push-pull one for the bypass. add a stereo jack w/ the ring connected to the battery negative, and you'll have a circuit that powers off when you unplug the cable.

[@JamesFord-g5e]

Cool idea using a transformer for as the pickups providers voltage to drive the transformer that gives more voltage output in the signal chain

[@robertpaddack9506]

This gives me an idea, wire into a guitar coil split circuit to boost the output on your single coil tones

[@Lordbaccus]

I need to give this a try

[@steverushforth7009]

Very interesting, the Yamaha Revsrar uses a transformer boost in some of the range

[@1mdlmusic]

Looks like a fun and useful project. Could you eliminate the pot and just wire directly to the jacks, so that when you step on the switch you get a 100% boost?

[@WaylonMcPhersonGuitar]

Yes, that would work great, + you would also get a tiny bit more boost, cheers!

[@gabrielvargas2459]

Your work is wonderful man! Your explanation of how does it work and the outcome makes it really easy to understand I've had studied electronics before to the point of achieving an associate's degree, but was always scared of some kind of messing with guitar pedals, (tried building an overdrive once but the capacitors didn't quite like the project) your channel has inspired to retry messing with pedals again, thanks a million for your videos man, keep going!

[@WaylonMcPhersonGuitar]

Stoked this has helped, it's such a cool thing to get into :)

[@TorySlusher]

As someone who mostly uses the neck pickup for jazz applications, and single coils in that regard as well..... it would be useful to solder this little circuit between the neck pickup wire and the switch (assuming that's where it would go)....

[@16GHunter]

You’re awesome man. Been watching your videos all week

[@WaylonMcPhersonGuitar]

Thanks a lot!

[@martysradioshow5979]

Wow i will try this my question is what is the volts of the transformers

[@CaptainErn]

This is a great idea! Would it work with a fender tbx pot? Like for the 1meg side controlling the boost and the 250k side acting like a volume control?

[@alexisvargaszapata9368]

I find the explanation interesting and super understandable but I have a question, I don't understand much about electronics. What potentiometer value are you using? Sorry, there are errors, I'm using the translator haha Greetings from Peru

[@thomaslthomas1506]

This is similar to what Yamaha did it the latest RevStar range. This would be slick to put in my crap Strat along with your revoicer circuit. Now I just need the time.

[@PearHellforge]

what do i do if i want to build it without on/off switch? this video is awesome btw, keep it up!

[@WaylonMcPhersonGuitar]

Thanks! , just wire the input jack to the transformer and the output jack would go to the Pot wiper, cheers!

[@Mr.Monster1313]

You ever think of doing cheaper fun basic pedal kits to build ?

[@WaylonMcPhersonGuitar]

Yes totally, that would be really cool, just super time strapped at the moment with the workshop being super busy with guitar/amp repairs etc.. Definitely something on the list though :)

[@thejoetandy]

would chucking this in an effects loop work, in lieu of a buffered pedal before it?

[@WaylonMcPhersonGuitar]

It should work straight up in most effects loops as they are already buffered, some use a Tube Buffer which would be pretty sweet!

[@rebeccacurrano1078]

You should always clamp the part (rather than hand-hold it) when you drill into metal, just to make sure it doesn't catch on the bit and whip around and hurt you.

[@Ma_X64]

You can also move the transformer's core in and out to change the frequency response (not the easy way actually but still passive). Another trick is to use a DC magnetization of the core to add some saturation to the sound. Permanent magnet works too but again, you need to disassemble the transformer. And if you find a transformer with two primaries then you can connect two parallel back-to-back connected germanium diodes in series with another potentiometer to get some distortrion.

[@Joseph-y6p]

To add another transformer, are you wiring those in parallel, or series?

[@Holiss]

Love your videos . I bought your schematic but I can't find these two types of transformer. can I use any alternative???

[@WaylonMcPhersonGuitar]

Thanks! Mouser.com is where I get them, cheers!

[@rebeccacurrano1078]

Is the Fishman pickup you're using on the acoustic guitar just a piezo-based pickup?

[@simonkormendy849]

Looks easy enough to build, I'll have to try googling the datasheet for the transformer to see if I can buy a similar specced one from my local Jaycar electronics store.

[@peterschmidt9942]

They're a 600:10K transformer although seem to be a little hard to get a hold of (at least in Oz)

[@peterschmidt9942]

So what is V2 doing different to V1?

[@jagr9228]

So it looks like you are connecting the guitar output which is a relatively hi impedance say 50Kohms into the low impedance 600 Ohms side of the transformer. Does that work? I can hear it here in your video but it would seem like a huge impedance mismatch . It sounds like there is some loss of bass frequencies which may be good in some applications or mayby not so good in others. Just a thought.

[@gtranimal]

Cant tell from the vid, is the bufferd Boss pedal seiched on or off when used before your pedal?

[@WaylonMcPhersonGuitar]

It's off, we just need the bypass buffer not the effect, even though that can be cool to :)

[@freesiaboysince]

!?!?!?!?!?!? really!?!?!?!?!?!?!? is it passive? no use 9v-battery and transistor? unbelievable、、、awesome!!

[@pegasusstation4977]

without watching for the answer yet, I'm guessing it uses a transformer to boost the signal ?

[@WaylonMcPhersonGuitar]

Yes correct! But there are some really important extra info you need to know before building :)

@@WaylonMcPhersonGuitar I have since watched the whole video. Some really great stuff on your channel. Good work, keep it up.

[@georgeirabor6715]

Would it be possible to have this built in to a guitar like a Jazzmaster? To replace the rhythm circuit

[@georgeirabor6715]

And to make it “active” it could rectify the voltage signal of the pickup to have a voltage source. I don’t know if this makes sense haha

Alright, time to try this with the old Boss tuner into the 5150 2x12 combo and see how what it does for the boosted high gain amp thing. Dangit - the tl019 is on mouser not tayda and I’ve got a tayda order going :/

[@zezohc]

After some multi-effect like POD or Boss Gt10, does it also work?

[@TheRealcdawg22]

It should. Basically, any active device will provide enough signal. Passive guitar pickups probably won't. I want to try it in an FX LOOP. I don't think that was ever mentioned.

[@WaylonMcPhersonGuitar]

Yep, it would work great in a Buffered effects loop, cool idea!
