I have no clue what is going on with this guitar. It's a Charvel, 2 humbuckers 1 volume, 1 3 way switch. This is a friends axe. I shielded the whole cavity, made said shield the ground and wired it according to the diagram. I've re-wired this thing 4 times now, my wiring is correct. I cleaned all the contacts as good as I could, re-stripped all the wire and still the same thing. When I roll the volume up half way it hums, full and it is quiet again. No audible sound from either pickups. :shrug: I know this Duncan diagram like the back of my hand and it should be working. I also tried a different pot, switch, and jack...same result. The pickups are brand new JB and 59. I really don't think both pickups would be dead?
