Out of no where I am suddenly experiencing the low E or bass E fretting out--- only when I fret the 9the fret. Can anyone tell me why this is happening? I do play with a lot of relief. Could this be the problem?. The frets arent that worn as its only a 2013 Traditional. Nut slot is kinda low but Id imagine that wouldnt matter since it doesnt buzz when played open. Thanks in advance!
