I'm putting together a Wonder Drive. I'm still new to this hobby. This is how I have it hooked up, with a Tayda 3PDT PCB. The LED powers on with the switch, and I get normal dry sound when the pedal is off. I get nothing when the pedal is on. I don't know if I need to use the V+ and ground at the top of the PPCB instead of going to the switch - using a multimeter I get a tone from the DC V+ on the jack to the "SW" on the PPCB board. I feel like that isn't where that can go... but I don't know anything.
