Thanks guys. These are all good places to start. And yeah, I know it mostly comes with experience, but it's still overwhemling simetimes just knowing where to start looking. Having some kind of checklist to go through helps. And in the end, it really comes down to re-checking everything, I guess.
I've got a small pile of builds that I need to debug, but I'll give you a basic example:
The pedal passes sound in bypass, standard 3PDT bypass switch. When engaging the effect, no sound, no LED.
Double checked my power connections, power is getting to the board, not reversed, etc. Check the voltage at the (board mounted) LED, I'm reading millivolts.
Using my test probe, I get a signal at the input jack in bypass. Engage the effect, I lose the signal at the input jack - what does that mean?? Do I have a short to ground somewhere, or?? This is where I get stuck. Again, I'll just have to dig in and start double checking all my wiring, solder joints, etc. I'm just hoping to at least rule some things out?
