Thanks! My Ax1500g's pedal switch volume is failing, and not reaching the 100% volume, not even 50%. I've opened the pedalboard and removed the pedal switch, but I notice It doesn't have any true connection to the switchboard but an LED with a PhotoSensor that may be blocked by a plastic in the pedal itself, is that how it works? I was expecting a Potenciometer.

Where can I buy the pedal switch board replacement?

309001200 PHOTO TR RPM-22PB N OR P KLM-2251 AX150 1

312051900 PHOTO SENSOR SIM-22ST Q OR R KLM-2251 AX150 1

Thanks
