Humbucker screws keep backing off
Any bright ideas on how to remedy this? The height-adjustment screws on my Telecaster humbuckers keep slowly backing off, lowering the humbuckers away from the strings, particularly the bridge pickup on the bass side. I put some foam squares in the cavities below the humbuckers thinking that'd help counteract some of the tension on the springs, but it's still happening particularly during gigs. This picture is immediately after a gig. I literally adjusted the pickup height right before the gig and you can see that it dropped significantly on the bass side. Should I try swapping out the springs with ones that have less tension? Put some thread locker on the screws to hold them place? Any advice much appreciated!
