Hey guys, i need your help. I'm trying to DIY repair my broken pedal, it's a ProCo Rat II.
The Issue: No sound when engaged. There's a signal when bypassed.
here's what ive done so far:
1. replaced a capacitor (C2) which i thought was faulty.
2. i tried taking apart the footswitch, seems like it's mechanism is working perfectly.
i have multimeter.... but i dont know how use it. hahaha
i cant do electronics for [gooey brown stuff].
so.. can anybody show me how to troubleshoot this pedal?
here are the gut shots & schematic
