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!
