Yeah, I'd like it all to be accessible through footswitches if possibleI've done it with a two boosts and a rotary - A, B, or A->B. One footswitch for the whole thing but I suspect you want more functionality than that.
I play scuzzy noise rock, so hiss and oscillation isn't too much of an issue for me. I'm just wondering how to wire it upIf you want to add a 3rd footswitch for series mode, the simplest way to wire it would make it behave this way:
switch 1 is ON/OFF.
switch 2 is A/B.
switch 3 is Series Mode. In series mode, the A/B switch doesn't matter.
Be warned: with that much gain on tap, the wiring layout is critical to avoid oscillation. You must keep the in and out wires far away from each other. Better to make the input wires shielded or twisted pairs (the other wire in the pair is ground).
Pictures of sketch-ups are suuuuuper usefulI'll work up a sketch & post it. The only thing I'm not sure about is on the A/B switch: is the LED ON when ch A is selected, or is it on for ch B?
OK, here it is. I was able to find a configuration with no compromises (no need to change R2a & R2b). In Normal mode, everything is interconnected exactly like the stock version. In Series Mode, the Input connects to Ch A input, Ch A output feed Ch B input and Ch B output connects to the Output. No changed to the the ON/OFF switch wiring. The LED on the Series/Normal switch lights up in Series Mode. If you don't need an LED on the Series/Normal switch, then you can use a 3PDT switch and wire the center pin on the A/B switch to GND. Someone should check this to make sure I didn't make any wiring errors.
