    Hi all.

    Last night I was installing 2 golden age pickups in too a les paul style guitar. The pickups consist of 3 wires bare negative/ground white for single red for humbucker.

    Wired up both pickups fine with split coils but in parrallel both pickups are out of phase. Easily fixed by swapping polarity of red and bare wire but then I am left with an ungrounded pickup that is noisey if I try to earth it it shorts(the bare wire is neagtive and on to pickup case)

    So I opened pickup to swap the case wire to the red but it is not possible...



    Anyone have any ideas or theories.......oes any one know of a passive phase inverter?

    It sounds like they dont want you to be able to flip the phase, its the price of having 3 wires instead of 4 or 5. The pickup case goes hot when you try to :eek:. Youd have to modify the pickups I'd say.

    Its best if you can get it so the case has its own earth wire and isnt connected to anything else, then you can have your conductor wires to flip with no earthing problems.

    my thoughts exactly tried to swap the wire coming of the case with no luck there is a lot of wax in there and from previous experience with cased humbuckers its nearly a gauranteed way to destroy a pickup
