...with my SG. No matter how precisely set, individual notes played around the first three or four frets are sharp, sometimes up to about 10 cents. The problem is especially acute on the second through fifth strings. First position chords sound pretty bad. As I move up the neck, the sharpness decreases; the intonation becomes acceptable at around the 5th or 6th fret, and is near perfect from that point up the neck. The neck is fine, the action is not too high, the intonation is perfect at the 12th fret, and I'm not applying undue pressure when I play in the first position. Could it have anything to do with the string height at the nut? Sometimes it seems that I could bring it down just a hair, so I'm willing to do that if I knew it would solve the problem. Otherwise, could it just be a Gibson scale length issue? Any ideas on either the cause of the problem or how to eliminate it? Thanks.
