Hi Guys,
Last year I had some Seymour Duncan Basslines installed (professionally ) in my Fender P-Bass Plus ( PJ Config ). I recently noticed that the magnets and pickup have dropped about a 1/2 centimetre!! The pick-up covers appear to be in the same position they always have been but the rest of it seems to be falling in.
Has anyone had this happen to them??? Do you have any suggestions on what to check??? I'd like to not make a fool of myself at the local guitar shop if possible.

Cheers
