I'm gonna make my own A/B box in the empty half of a funklogic rackmount kit for my FMR compressor. Bob Gollihur graciously sent me a schematic for how to do this, so now all I have to do is get the parts. That's where you guys come in. I was checking Radioshack.com and they have about 400 different 1/4" jacks. I'm guessing I want plate mount mono jacks, but there were a few of those to choose from. I also need a DPDT switch. Where can I get one of those?
