Today I ordered a Carling progressive 3 way on-standby-off switch for my Blues Jr III. I got it from Antique Electronics and it seemed like a pretty cool mod for only a few bucks. Does anyone know how to install it? What wires hook up where? I know basic safety stuff (hand in pocket, discharging caps, etc.) I just don't know how to wire it. Any help or instructions would be much appreciated!
