Hi Friends. I need help!.

I've build a few pedals before, but I can't seem to get this one to work. I have sound coming through when bypassed, but nothing when engaged. I know the first thing to check is a ground problem... I can't see or find anything. What else can it be. I've gone through all the solder joints, swapped out the IC's as well. I'll post some pictures, maybe I'm missing something stupid. The big orange cap on the is a 100v as I couldn't find anything with a smaller voltage, but from what I understand that can't be the problem? Really hoping someone can help me get this pedal going.

Wow I’m surprised it makes it that far. It’s reaching pin 6 of IC2? Sounds like the effect should?

Edit: read your message above wrong, though you meant it dies at pin7 of IC2. All signs still point to issues at IC2 (either the chip or surrounding components)

Yeah my idea oils basically just run IC2 on 0v - 9v (or a little less) instead of the designed -9v - 18v. Audio should work this way (checking if the charge pump chip itself is bad).

With the probe, we’re you able to find the point at which volume drops?

I have swapped out the charge pump, with no result. Without the charge pump the audio still drops a lot

If I follow the result correctly so far, it seems like an issue in the IC2 area (whether the chip or something else).

You could remove the TL072 (ic2) and check the voltages again. (With the charge pump back in). The voltages were weird before. We’ll see if removing the chip and measuring at the blank socket works.

You could also just try a replacement in IC2
