My guitar is perfectly in tune, but when i climb to the higher frets (12-24) the notes get more sharp as i go higher. I checked the harmonics and they match up with the note too.

is it a truss rod/neck problem?

try fretting the 12th fret, make sure its in tune.

By how much do they get sharper?

Assume your action is reasonable low, and you're not pressing too hard?

BTW, the harmonics can't be in the wrong places by definition (unless you have strings that vary in thickness along their length) - so that I don't understand.

nope not pressing hard at all, and the go a quarter of a semi tone approximately. So it pisses off my ears.

guitar is 90-92 left handed kramer baretta just for background info

Maybe you need to adjust the saddles, but only do that when refreshing strings. Don't ask me why, I forgot.

why adjust the saddles, isnt that for intonation? the saddles are already in the correct positions?

The fretted note at the 12th fret is way to check intonation not the harmonic. That said the guitar is an imperfect instrument.You can get intonation close up and down the neck but not perfectly in tune the entire length.. If you want perfection take up piano or the oboe.

The following statement is true. The proceeding statement is false.

yes but usually notes are not quarter of a semi tone different.
i can understand i little bit, but its extremely noticeable.

When I learned to do it I was told do both. When I intonate my guitar I get the 12th fret in tune, then check the harmonic and usually have to do a minor tweak to get the harmonic in tune. 12th fret is probably good enough but that's how I learned and how I've done it since.


Sounds like the neck is bowed, raising the strings further from the fretboard.

I always set intonation at the last fret (24th or 22nd.) When intonating at the 12th you still often hear it go out further up the scale, but when intonating at the 24th it tend to be much closer over the entire length of the neck.

I just went to a setup clinic this past weekend (not a freebie).

It is the open string vs. the fretted 12th (pressing just enough to get a clean note - 12th is 1/2 way). If its sharp at the 12th, you need to move the saddle toward the bottom of the guitar (making the scale length on that string longer). Tune and check again. Repeat as necessary. If you can't move your saddle back any farther, you need to seek a professional (other issues are in play).

Assuming your neck relief and action are good.
