weird buzzing problem at one fret.
I bought a used rg570 from like the 80's. The guitar is awesome except for one problem, if i fret any string at the 9th fret the string buzzes and chokes like crazy. I really dont know why, at any other position the action and feel is fine its just at the 9th fret i get this problem. The fret seems to be seated correctly, ive tried bowing and straightening the neck, it doesnt matter its still the just this one fret i get this crazy problem.
anyone else ever encounter this or know what the problem is?
