    well, darn near anyway. Guitar tuned standard, 12th fret intonates to ‘E’, but when fretted at first fret it plays about 1/3 step sharp. The action is low, the frets are all planed with each other well. Are my frets too high? I do have a fairly heavy touch, but I never considered it too heavy. BTW, the other strings fret sharp at 1st fret also.

    Measure it out and see if the fret was spaced correctly or not.

    Thanks, Walter; I was hoping you'd respond. What parameter(s) do you use for establishing nut height? If I lower it much, I'm afraid it will cause a buzz.

    hold down the first fret and look at the string height over the second fret; that's your goal for the open string.

    you can't quite get there but it should be almost as close

    the other way to check is to hold the string down on the other side of the second fret (so between 2 and 3) and look over the first fret. that gap is the difference between your frets and your nut height, and should be almost not there.

    One other thing to also make sure of is that your relief is set where you really want it to be before you start filing down your nut slots.

    Yeah . . . Before you start filing ANYTHIN down, figure out what the problem is . . .

    You said the action is low, including at the first fret? Does this only happen with one string? What's the history of the guitar? If it wasn't always a problem, what did you change when is started?

    If you think that you "heavy hand" is the issue, you should be able to test by going more gentle. Don't start making non-reversible changes until you know where you are.
