Changed the switch. changed the wire harness and the pot for that pickup. The other 3 pots are original input jack and the caps. Do you think they would interfere with the pickup?
i saw a Wolfgang in a shop i worked in and they told me to fool around with the neck pickup and see if it works at all... for whatever reason it was dead..... no signs of life.. it was not the switch or the pot or the wires.. the PU itself had a problem... I assumed one of the little wires soldered onto the pickup base may of broke somehow... but you could not see it by eye... i was stumped..... the real tech took a look at it after i was done.. i could not for the life of me figure out why it was dead... no signs of damage....
