I am in need of the footswitch wiring diagram for a solo 50 series 1. I would love it if I could get a schematic for the footswitch or some pictures of the inside wiring. I tried a stiletto footswitch on my solo 50 sereis 1 amp, and the solo button worked great, but the channel button did not change channels. The LED would light up, but no amp channel switching. I tried to rewire the Channel switch without the LED, and channel switching worked fine. Am I missing something? Any helpful hints? Thank you in advance
