Hello,
Recently I've put new strings on my guitar, and I did a setup and adjusted the intonation. Most of the strings are now perfect, but the low E and G strings are about 15-20 cents sharp and the bridge saddles are adjusted all the way back for maximum string length. I think the problem is that I had previosly used 11 guage strings and they seem to have cut into my nut at the part near the tuners. Is there any way I can fix this, or should I just get a new nut? If I buy a new nut, is there anywhere I can get one cut for my string guages? (010, 013, 017, 036, 052, 060)
