Hey all,

Wondering if by this image yall can help me sort out where the gain is on my pedal. Per an earlier thread by @NickC , my pedal isn’t generating any distortion/clipping, but rather gets more compressed a little quieter when I turn the gain up.

Ic Values:

IC1 : 3.57, 3.57, 2.79, 0, 3.57, 3.57, 3.57, 7.14

IC2: 3.57, 3.57, 3.57, -6.68, 3.75, 3.75, 3.57, 12.4,

IC3: 7.13, 3.64, 0, -3.29, -6.67, 2.91, 4.42, 7.13

One last note: I reflowed everything so it may look a little glooby. Don’t shame a lowly novice ….

Thanks everyone !

Use your meter to verify the gain knob is working correctly. Check for resistance between lugs 1 and 3 and make sure it matches the pot's value. Then check for resistance between lugs 1 and 2 and then 2 and 3. These two measurements should add up to what you got between lugs 1 and 3, and they should change as you turn the knob.

The gain control is a dual gang so do this for both sets of lugs. Since you have an issue as you turn the gain knob, let's check that first

@falco_femoralis i was getting a little weirdness out of the readings i was getting on the pot, so i went ahead and replaced it with a tested, functional one. Same general problem.

@Nostradoomus i have a plastic shield over the back of the dual gang to make sure it doesn't ground to the board. Good ask tho.

I have worked through all the resistors checking values up to R28. Only a few were off, but not by enough to raise an eyebrow. I went ahead and replaced them all the same. General problem still persists.

Thanks again

Somethings not right with your voltages.... Your not getting close to 18V out of your chargepump if you've measured and recorded correctly

yeah i thought the same thing. i'm going through all the values leading up to it to see if maybe something isn't reading correctly... like, maybe a grounding issue somewhere but i can't seem to find anything that could be causing it so far. The Germs have appropriate behavior for what i can tell. Going to go over the caps in the next day or so, eventually getting to the other diodes

yeah, heard. i swapped out one of them for a smaller ceramic version already. i'll swap the other film one this evening just to make sure. the values are correct, for what it's worth

There's a 390 nanoFarad in the BOM and a 390 picoFarad. It looks to me like you used the same for both spots. That said, there are a million different capacitors out there, and maybe it is in fact a 390pF that's rated for 600V or something. That would work fine, even if it is enormous. Sometimes we have to use what we have on hand.

Ohhhh jeeze i think you found the issue for me. what a saint. i'll see if i can get that correct....

Well, that fixed it! Gosh i can't believe i overlooked that one. I remember even remarking on it as i was initially populating resistors, noting that i needed to make sure and get the pico's and nano's correct on the 390s.

Thanks for saving me a lot of time and frustration. Ya'll the best!
