Hi All, I'm modding a cheap Precision copy. I've put in Epic custom shop pickups (F1 for P Bass) which sound immense, but the input jack is crackling like hell. So... I have the pots and jack from a MIM Jazz which I've previously modded to a stacked knob setup. Someone must have done this before - using 1 x vol, 1 x tone and input jack from J in a P... Bad idea? Will the 'cap' be all wrong? I have no idea..
