using a 3pdt switch, im trying to wire two mono jacks (neutrik/re'an slimline).
ps im working with the ross comp pcb. having trouble locating the 9v+ and input.
the 3pdt wiring schem i got from GGG says the top ring on the DC jack goes to 9V+. and the bottom middle lug on the switch goes to input.
For output, a mono jack is fine.
You can use a mono jack for input, but a stereo jack is usually used so that the effect turns on only when you have an instrument cord plugged into the input - if you use a mono jack it's much easier to drain a battery by forgetting to switch an effect off.
I used to have an old big muff that did this, it had a switch on the top that turned off the battery. I thought it was kind of cool b/c if you didn't have a power supply, you could just leave it plugged in the pedalboard and not have to unplug a cable to shut off the battery.
