I was trying to adapt an old set of EMG PJ's to a new BQC preamp by soldering the old pickups onto the spots on the ABC control's PCB where they tell you. Unfortunately, I am a lousy solderer and it didn't work so well, so I undid my solders and tested the circuit with a newish set of PJX's that uses quik-connectors. I confirmed that the quick connector hookup for the neck pickup is fine but the hookup for the bridge pickup isn't working. I have a little meter, but I have no idea what to do with it to check for continuity. I visually inspected the pot and I don't see any areas where I might have shorted something with my bad soldering. So my questions are: 1. How do I set my meter and what do I touch to check what's wrong? 2. Can I fix it? 3. Can I just solder quick connector wires onto my pickup wires and hook up the old pickups as if they were quick connector pickups? Here's the PDF on the ABC control for those who aren't familiar: http://www.emgpickups.com/content/wiringdiagrams/ABC_0230-0095H.pdf Thanks!
