Adjusting Intonation
Your Jayemar 6-, 7-, or 8-string guitar features a proprietary multi-scale bridge plate, co-designed by my good friend John Sonksen.  They are milled out of aircraft aluminum or bell brass, and are mounted with Graph Tech Wilkinson-style saddles.  Follow these instructions to adjust intonation (especially if you change string gauges).  As always, if you are not comfortable making adjustments yourself, reach out to Jason for an appointment in the Portland Metro area, or recommendations for a guitar tech in your neighborhood.

1. Tune a string to the 12th fret harmonic.

2. Lightly play the 12th fret and check the tuning.  The harmonic and fretted pitches should match.  In this example, the fretted 12th pitch is sharp so an intonation adjustment is needed.

3. Slacken the string.

4. Using the 2mm hex wrench (2nd smallest wrench in your tool kit), loosen the saddle anchor screw.

5. With the 1.27mm hex wrench (smallest wrench in your tool kit), adjust the saddle intonation screw.  In this example, since the fretted 12th pitch was sharp, the distance from the 12th fret to the saddle must be increased.  Turn the saddle intonation screw clockwise a few turns.

If the fretted 12th pitch was flat, the distance from the 12th fret to the saddle must be decreased.  In that case, turn the saddle intonation screw count-clockwise a few turns.

6. As you retighten the saddle anchor screw, be sure to hold down the saddle by pressing down on the back edge.

7. Retune the string and check the intonation with steps 1 and 2.  If the fretted 12th pitch does not match the harmonic 12th pitch, repeat steps 3 - 7.
