I have a P bass that I've owned for some time now and never had this issue before, so why would it suddenly happen?
It's not a slight buzz, it's a full blown rattle, I've checked with a metal straight edge over the three frets (6, 7, & 8), and there is no rocking, so they appear to be level.
I've tried filing the next fret a little bit, I've tried adjusting the truss rod, and I've tried altering the bridge height, all to no avail.
Any ideas on why I suddenly have fret buzz on just one fret?
Thanks in advance.
