I'm sure there's a topic for this somewhere, but I scrolled and didn't see one so anyway.
I got my Japanese '65 Mustang reissue last year, and every time I use the vibrato it sends the whole thing out of tune. The weird thing is that sometimes it just drops the high e and b strings but then sometimes it actually brings the whole thing up, and that'd not depending on whether I push or pull the whammy.
I pretty much know nothing about bridges and tail-pieces, but I was just wondering if there's an easy fix or if I'm going to be saving for upgrades? Any help I'd be much obliged.
