I haven't contacted GK yet, but thought I'd ask here first — looking for the schematic for this GK footswitch used on the 112SC, 212SC, 150GT, etc from ~1980. The PCB inside is marked 50033B. The unit I received was DOA and someone disconnected the leads to the B channel switch at some point. I have a 112SC to test with.


This is not exactly what you're looking for, but does show the footswitch to preamp wiring.


A little further searching and, Bingo!
