Probably should've left it alone, but my fat e-string sounded a bit sharp. So after working on that string, decided to check and adjust the others. I'm about done fartin' with it, but it's not perfection by any means. Obviously, you check at the 12th fret and mind you I'm using a Super Snark head stock tuner. I'm not doing the harmonic thing at the 12th, simply fretting the note. I can get the 12th fret of every string dead nuts but as I move towards the nut, some notes go sharp. Normal? Most of the sharp notes occur between the nut and 5th fret. Nut slots too high? Too much relief? Obviously, the harder I fret a note, the sharper it goes. Do you set intonation at the 12th fret with "normal playing pressure"? My string action is actually quite low and I'm two years into a fret level/dress job.
