I'm working on a "super strat" style guitar. Single, single, humbucker. I've tried two humbuckers and both refused to work. The two single coils are OK. I switched from a JB in the bridge position to a 59. I'm using just a volume and no tone. I'm out of ideas for what to do. When I try to fix something it just seems to get worse. There is now an issue with the jack as well as the humbucker. I know the pickups are good, there is just a flaw in my wiring somewhere.
