Hey guys! So I have had this guitar for a while and have been dealing with the fret buzz specifically on the 8th and 12th frets accross all strings. I finally caved and decided to get a fret level done with my local luthier. Well, I get it back and practically the same areas of the fretboard still buzz like a bitch. I originally thought it was maybe the truss rod needed adjusting. I ruled that out because when I moved the truss rod in either direction, the buzz got worse on all the strings. I have graptech string saver saddles on it. The only thing I haven't replaced is the nut. I don't think the nut is the issue however, because if I capo the first fret, the buzz stays. What else could the problem be?
