That is just too weird ... Like, I mean, this is a "solid body guitar ? Right ? Just yank off the pickguard, and take a look
Something has come loose, or been "included" where it should not have.
The easiest place to look first , will be the Trem cavity (biggest hole, no strings to loosen) But something is not right ...
Kinda like the days , when disaffected auto workers would put a beer can inside a door frame during assembly, to drive
the buyer crazy

... (and tick them off against the car make)
