Aparently I dont understand how to get correct intonation from the guitar I just built. I tuned it to GDG and then checked the harmonic of the thickest string against the open string and the fretted note at the 12th. The harmonic and open string are close to each other. The fretted note is sharp.
All my frets are level with each other. I've destroyed two nuts and have refretted the guitar and resanded the fretboard perfectly flat.
What am I missing?
