I’m having some issues with a Mach 1 I built for a buddy of mine awhile back. This is the same pedal that had the screwy gain pot. I replaced the pot, tested the pedal, retested it, then tested it a couple more times for good measure, and everything worked fine. Take it to my friend, we play it, he’s happy. He called me up the other day saying it’s not working. It passes sound in bypass, and the led comes on when you hit the switch but it’s dead silent. I swapped op-amps and no change. The VDC on the op-amp (from leg 1-8) reads 2-2-1-0-2-1-2-8. My next step is gonna be re-flowing the input and output joints on both the board and the switch, but beyond that I’m running out of ideas. Do any of you have any suggestions on what else to try?
