I have continuity between lug 2 and the tip of the output jack. Checking the switch I get the following: 1 has continuity to pcb input 2 does not have continuity to output tip but does have continuity to input tip 3 has continuity to 9 4 has continuity to sw pad 5 has continuity to ground on...

I'm not in a position to do any more testing tonight but when I tested earlier I had continuity between lugs 2 and 3 when fully cw and continuity between lugs 1 and 2 when fully ccw. I will run through the switch again in the morning.

My brain isn't braining and my pedal is starting to laugh at me. I get bypass signal. When the circuit is engaged, signal cuts out. Continuity on the switch and breakout board seems to test out fine. When I connect the breakout board to the main board and have the switch disengaged, which of...

Better clarification. I get signal on the volume pot input side but nothing on the wiper leg. I've swapped pots and got the same results. Any thoughts?

Hadn't tried that yet because my test amp was down. Got it fixed and ran a test. I get signal on the sustain pot (b100k) that is equal to my input signal (1khz square wave). Signal on the volume pot (b100k) is there but barely noticable when turned all the way up. Will send some scope...

Have a muffin fuzz, green russian version, that I built a few months back. Worked well but then stopped working. Looking for some advice on where to start. I've reflowed everything and have started chasing voltages. Any thoughts would be appreciated. Think I am too close to it and frustrated 🥴

Clearly I was pretty slow!

Really enjoyed building this one! Everything went together smoothly and it sounds great! Wish the rate was maybe a touch slower but that's not really a big deal. Forgot to order knobs and I haven't had much success in coming up with art work, so the labels are just temporary. Also learned...

@HamishR what effect will the 500pf/56k have on the tone over the 500pf/33k?

That was what I figured the smart route would be. Or........

I am getting ready to build a mojotone 100w British head and I have been trying to decide between building the super lead or the super bass version. Wondering if there is a reliable way to mod the design so that I can switch between the two? Has anyone done this or something similar that can...

That is an impressively timed jinx - Thanks for the help!

I'm trying to get my hands on a couple of V3207Ds but all of my normal sources seem out. Has anyone seen these in the wild recently?

So, maybe this is a dumb question but, can the inkjet version of this paper be adapted to this technique? Has anyone tried it with positive results?

Grape slurpee looks great!

Turns out that schematic doesn't exactly match up with the cf variants, which is why I wanted to get some feedback on the picture. Thanks for the help. Now I just need a place that has them in stock 😞

This comes out of a little Marshall MG10CF, which I can not find a schematic for. Looks like a blown up TDA2030A but there isn't enough left of the printing to verify. Can anyone let me know if I am chasing down the right thing?

Any specific reason you would use a film cap here?

Thanks!

See attached schematic for a power section. C27 (100n) is called out as being ceramic. Wondering if someone can explain why this choice was made and how it would affect the circuit vs using film?
