Pretty much a Colorsound Overdriver clone. Laid this out for a 125B (because of the dual footswitches) with board mounted pots. The boost footswitch bypasses the PreGain pot and only uses one side of a DPDT. Use the other side for LED wiring. If the off board wiring is confusing, check out the thread with the schematic here on FSB. The diagram is for a vero layout but the wiring is the same.
