Play the harmonic at the 12th fret, compare it to the fretted note at the 12th fret, these notes should read the same on the tuner. Before adjusting the intonation, first determine the direction that the saddle needs to be moved. If the 12th fret harmonic pitch is lower than the fretted note, slide the saddle back. If the 12th fret harmonic pitch is higher than the fretted note slide the saddle forward. * (Adjusting the intonation and string height will affect the playability of your guitar.
