Trying to get my old SG kit back in action. All pots are working. Switch working in two positions (neck p/up and both p/ups) but not working for bridge p/up. Have re-soldered several 'suspect' joints and the wiring layout is correct for an SG (ie switch going to centre of pot lugs). It's possible I suppose that the bridge p/up is faulty but not sure how to test this. Bought a multi-meter but having trouble understanding how it works (on resistance). Any ideas?![]()
