I have a 1965 Fender Jazz bass and am finding that the pickguard is tending to shrink. Due to this shrinkage, the pickups became gripped by the pickguard - an easy fix for this was to enlarge the pickup slots. A more difficult problem to address is the screw points along the edge of the pickguard. As the pickguard shrinks, the screw holes pull in, thus misaligning the pickguard screw holes from those drilled into the body. Now some of the screws angle slightly inward. I see pictures of old Fenders with a tip of the pickguard missing, possibly due to this shrinkage and resulting misalignment of the screw holes causing too much tension. I'd hate for that to happen to my bass! Has anyone encountered such a problem and can lend some advise?
