So I will update this with some pics later, but I dont think my nut is cut deep enough for my low E/F 0.80 gauge. I had really bad buzz on the 4th fret and it was just kind of muddy in general, so I tuned it from E to F see if I could get it a little cleaner. So the open string is an F first fret is G?!?!? it basically stays out of tune by a semitone up the first 5 or 6 frets. If my basic understanding is correct.... the string is travelling to far when fretted so it is sharp because i am pulling down more of the string than is needed to hit that note, which is likely due to the nut being too high.... it's ridiculously high btw, I'm just at work and can't get pics.
