The low E string on my 314ce has a tuning problem. While all the other strings stay in tune up and down the fretboard, the low E, if tuned correctly as an open string, goes slightly sharp moving up the fretboard (causing me to tune the string slightly lower when open, so that other fretted notes are right...but this means that open chords have a slightly flat E string!). Thoughts? Something with the nut or saddle?
