Roy's Guitar, Intonation Nation

Intonation is the pitch accuracy of a musical instrument. Or in guitar terms, the open notes in the lower register are in tune with fretted notes in the upper positions.
The steps:
1. Strum the open E string.
2. Using a good tuner (picture) (I salvaged this one from an old school's music room that was being gutted when I was 16) tune the open E string.
3. Now, fret the string at the 12th fret, this is the "high E" (picture), the tuner is telling me the note is flat.
4. Adjust the bridge (picture) by moving the E-string saddle forward until the open E is in tune with the fretted E.
