Well, I completed my second build today... and it didn't work. This is the second one to make no sound when on and a lot of hum when bypassed. Man, frustration is plenty :(. Anyway, both jacks make a popping noise when the cables are plugged in, so I don't think that's the problem. However, if I play hard, and the pedal's on, the led flashes and turns off immediately. Any help would be appreciated! Pictures to come. Thanks!
"A lot of hum" is usually a ground issue. Having your LED react to your guitar signal
Post your voltages, double check your wiring again.
Is it in an enclosure?
How are you powering it?
