I just got in a 74 Jazz at my music store. I adore the neck and the bridge pup has a lot of bite, so I've already set aside some money to buy it. I noticed, however, that the neck pup was very very weak. I initially thought it was an open circuit but I stuck a multimeter on it and it read 3.8-4k. I looked at the wiring and thought it maybe be grounding out on the ground strip, but alas, that wasn't it either. I'm stumped on this thing. I really want to buy it but I want to fix the neck pickup before I drop serious money on it. Any suggestions?
