Hi, thanks for reading. I have a 2011 Jazz 24 with Bassline Quarter Pounders. I rest my thumb on top of the neck pickup for an anchor. My thumb pad rests against the E string. When I pluck the A string, my plucking finger then slaps against the E string and I get a short "AANK" sound almost like a fret buzz, but it comes from the pickup. This only happens if my thumb is in contact with the pickup. Just tapping on the pickups with my fingernail makes a lot of racket, even if not plugged in. They sound hollow. Any ideas for a fix? I've used the pup for a rest for many years, hate to try to give that up. Thanks!
