Ok, here's the deal in a short version: Spector Zebop 5 string. E string 2 to 6 fret (especially 3rd) buzz after plucking a long note. Tried truss rod and action adjustments for quite some time but it doesn't seem to fix, only with rather high (for me) action. The strange thing is, that qhile the B string has no prob at all, it happens on the E only! Can you please suggest me some solutions?
