I have 2 FENDER Pro Tube Pro Reverb amps that have a 4 button foot switch #0057025000* that has malfunctioned. I understand that this has been a common occurrence with this foot switch. The channel select button and the vibrato button work, but the switches for the reverb and effects loop do not. Since this is done on a PCB I'm wondering if it's fixable? If not, is there a good (better) substitute foot switch that will work with this amp?
Thanks!
*used on all Pro Tube series amps.
