Is there any way I can use the gain toggle to toggle between cathode bypass and unbypass, or two bypass values here? More importantly, can I connect simply the Cathode Bypass concept to the gain potentiometer, and how is that done? Initially I am thinking of a 25uf/150kohm combo at V1 pin 8. Here's an image and the schematic. I am looking specifically at V1. Secondarily, does anyone know what particular type of footswitch I would use for this amp?
