This is Roger Arts' (http://guitar-effects.weebly.com/) design. I only made the DIYLC layout for it.
It switches one only of fx A, B or C. Left switch will select C or whatever the other switch is set to and overrides the A/B switch. This way you switch between A, B or C. Bypass is easily added, another 3PDT is needed for that. Led for C is on only when C is selected. Led for either A or B is always on, allowing for pre-selection. De-select C and either A or B is active. Make sense? Me gusto mucho this switch thing. I'm using it to switch between 3 different ODs and another to switch between 3 different FUZZ pedals. An additional A/B switch is used to select between the two loopers.
AA position is fx IN, AN position is fx OUT, red goes to PWR, black goes to GND. Left green wire is IN, right green wire is OUT.
Question; how do I add text to these layouts? I've only downloaded the software yesterday and this is my first project (hence the squiggly look). I'd like to add some notes...
