I recently traded for a Sterling AX40, which I love, with one glaring exception. The locking nut is so bulky I'm constantly chaffing my index finger on it on first position chords and playing notes on the first fret. It's so bothersome I can't see myself not doing something about it, either buying another low profile style, if one even exists, or filing this nut so there's some relief. I have a hard time to imagine I'm the only one suffering from this. Opinions?
