Maybe this will help Glen:Hello folks,
Does anyone know where a guy can find newer gibson schematics? or perhaps anyone have one? The way this one is set up, the only way to do any tracing would be to pull out the main board & follow the traces...it's a 2 sided pcb.
Issue is channel 2 has way less gain than channel 1. Trying to follow the minimal traces on the exposed side of the board or signal tracing the known pins on the 12AX7's is yielding no help. It has switching transistors all over the place for selecting different functions too
