On a guitar with 24 frets, do you use the 24th frets to intonate it, as opposed to the 12th fret method?
#2
use the same metod as with a 22 fret check it at the 12th fret.

This thread will probably moved to electric guitar.

No, you probably still use the 12th fret to intimate it.

You use the 12th fret method on any guitar because the open string and 12th fret notes are octaves of one another.

But the 24th is another octave, and I know it doesnt play in tune around the 22 frets.

Yes, but I believe it is easier to use the 12th for intonation. If I'm correct this is because the string vibrates in a wider arch when played at the 12th which enables your tuner to pick it up easier.
