I have two J45 pickups by Bill/ Wilde pickups and a 3 band pre. The issue is this is preamp number 2 and I now know the problem is the blue wire that comes from each pickup. They are not ground nor can they just be disconnected as I have tested both options now. I am getting extreme noise from them whenever the treble is boosted and it goes away when the strings are touched. Everything is grounded properly I just need help as to where to solder these blue wires.
