i rewired a squire jazz bass a while ago, and i've been pretty happy with it. BUT the pots have always been loose/wobbly. is this at all a normal thing for a jazz bass? i wouldnt think so, but having a metal shaft running thru a metal plate, held in place by metal washers and nuts says differently. all i know is i put the ridged washer on the inside and the smooth on on the outside. and i really dont think i can pop off the knobs to tighten the nut without tearing some of the wiring inside or breaking a screw. so wat is it exactly?
