I have an issue where my main amp control knob will no longer function. It is stuck at 5 amps. Does anyone know how I could fix this issue? Is it a as simple as replacing a board?

Thanks in advance.

Gee,

Call the support phone number to get a direct response and course of action.

I mean, maybe it's just the rheostatic dial that can be swapped out.

What does it show when your foot pedal is unplugged?
