I think I found the YouTube video on 3rd fret intonation - https://www.youtube.com/watch?v=cifXWMlcI_I&feature=youtu.be
In some ways it makes sense since a lot of chords are done on the first 5 frets, but this person intonates with a digital tuner by fretting the 12th fret instead of using the harmonic. So when he frets the 3rd & uses a digital tuner it's not accurate... right? (In the video the 3rd fret was already in tune & didn't need adjustment.)
I just got an inexpensive Cozart 12-string Tele & put new light gauge strings on it. I set the intonation at the harmonic 12th fret but when I play 1st position chords I'm out of tune. Is the nut too high? When I capo the first fret my chording is in tune as the action is low. Thoughts/help?
thanks, Greg
