I have a G&L SB-2 (P/J combo) I absolutely love the feel of this neck along with the weight of the body. It seems when i start going above the 12th fret I am getting fret buzz on the E and A strings. The D and G strings are fine. I look down the fretboard and it seems straight. Maybe it is too straight and needs some relief? Maybe the bridge saddles need to be raised a hair? What do you guys think?
