Does the black/white wiring on a Jazzmaster matter?

    Hi guys,

    I just did my first soldering experiment today with my Jazzmaster J Mascis. I put in a pair of Pure Vintage '65s. However... I wasn't sure which was the 'hot' wire on the new pickups, so I soldered the black wire to the place where the original black wire was soldered to (the 6 prong switch and the 3 prong switch for the neck and bridge respectively). I soldered the white as the ground in both cases - to the pot and to the opposite side of the circuit as the original wirings were.

    The guitar sounds great, but I need to go back in and adjust the height of the pickups by adding foam... turns out the old pickups had quite a bit of a lift from being tall pickups.

    Bottom line:
    1) I wired the pickups consistently using the black line as the hot and white as the ground for both pickups - Should I go back in and reverse this? Is there a downside if I am getting a signal? Would the reverse wiring give me a higher output??

    2) Let me know if you have any tips on how to bring up the height of these pure vintage '65 pups in the Jazzmaster! :)

    There shouldn't be a downside to wiring them consistently. Single coil pickups don't have a hot end and a "cold" end, they just have two ends of the winding. As long as you're consistent between the two pickups, everything should work as before.
    (Pickups with a metal shield that is connected to one end of the windings don't have this property, e.g. a Tele neck pickup.)

    Exactly - I did this after following Caddy’s lead, but I’ll let him chime in here and tell you what to watch for.

    If it sounds right, then its probably correct. I'd leave it alone.

    Not sure if it would change the output or sound, but the black should be the ground. I put a set of Fender '62's in my VM Jazzmaster a couple years ago and it sounded thin and out of phase. Evidently the factory had reversed the wires on one pickup when they soldered the leads on. Switched the wires on one of the pickups and problem solved. Sound great.

    Keep in mind that those PV '65 pickups are probably only about 6.75K ohms, so not high output. Vintage wound as they should be for what they are, '65's. They should sound great, as do my '62's.

    Thanks for answering "the call". I knew you had the info for the original poster...

    Thanks for the input, guys. Very useful. I’ll focus on bringing the pups up to the right height.
    Hopefully I can also eliminate a bit of the noise :)
