Sorry if this is the wrong forum on the board to post this, but.... I bought a DigiTech Synth Wah pedal off of eBay. It was listed as not working, and my brother volunteered to fix it for me. Got it for a song and a prayer. He's gone through most of the pedal, but just can't seem to chase down the exact short in it. Does anyone know where I can score a copy of the wiring diagram?
