Hi, I'm trying to source a Pedal PCB for my PodXT Live. The pedal function has died - both Volume and Wah, and I've reset software/firmware and updated all drivers and flash mem, pretty sure its either the light emitting diode or the opto-transistor on this PCB that is faulty, so need to swap the PCB. Part number is 50-02-0032. Does anyone know where parts can be obtained or perhaps someone is breaking one for spares ?? I'm attaching a picture of the PCB Thanks LesM
