I'm working on a Les Paul that is exibiting some strange symptoms. When the bridge pickup is on, the volume drops significantly as compared to the neck pickup, and it also distorts like a battery is dying, except that there's no battery in a Les Paul. I've already cleaned the pots, inspected all the solder joints, and even took the tone control out of the circuit to make sure it wasn't the capacitor dying. I can't figure out what's wrong. Any suggestions as to what to look for?
