You will need a schematic. Use some small amp as a signal tracer (or and oscilloscope) and locate the amplifier stage causing the noise. You will find a noisy transistor (likely) or a noisy resistor (less likely.) But they will be in the preamplifiers before the expression pedal. If you don't know how to trace through an amplifier circuit, it's a job for a service technician. R. Ahlvin |
