I have this MIJ Fender '66 reissue that I really like, best Jazz bass I have owned but the bridge pickup seems to move a lot in the cavity and when my plucking fingers hit it, it makes this pop. It doesn't get transduced through the amp but it's annoying. The pickup height is where I want it. It's almost as though the screws holding down the pickup are too small for the holes they are in so the whole thing moves around. Anyone had this experience?
