Mustang Intonation Problem

66 mustang.
When I test the G string open, then at the 12th fret, I get that it's sharp.
When I test any other octave, such as 5th and 17th, it's reading flat.
Any ideas? Thanks in advance.

I'm using 11s. I believe I have a pretty straight kneck.

a couple of questions.


A. how sharp and flat are we talking?
B. I assume when you mean 5th and 17th octave, you mean fret?
C. Is it the original nut?

A: If any fretted octave is adjusted correctly, the open to fretted 12th fret will be approximately 7-cents sharp.
B: Correct. I mean fret.
C: Original nut.

I've had no problems with the intonation on my mustang, but i have had on the g string of my jagstang and some sort of fuckin annoying intermittant string buzz.I've considered swapping out the whole bridge as the screws for the saddles are very very close - nearly touching- to where the string runs over the saddle.Not sure is this is summat to do with it.

Isn't ~5 cents the industry standard? I can never seem to get them closer than that.

It's physically impossible to intonate a guitar 100% accurately, although the Buzz Feiten system gets a little closer.

If it's audibly out of tune (rather than just what your tuner is saying), it's likely to be down to your nut, action or truss rod, or a combination of one than one of these.
