SC-13E SET-UP & ADJUSTMENT
1. Loosen the strings and the two neck bolts. Neck bolts are set to 25" lbs. and are tightened with
a torque screwdriver and a 4mm Allen wrench adapter. It is not necessary to remove the neck
completely from the body.
2. Remove the plate by lightly pinching the ends.
3. Choose the appropriate plate height (to raise or lower action) and insert until it is securely in
place.The CFM logo should be facing up.
4. Ensure neck is in the proper place, seated against the intonation set screw, and re-tighten the two clamp-
ing bolts to 25 inch-lb of torque.Tighten the lower clamping bolt first (accessible through the middle of the
decorative grommet on the back), then the upper bolt (the head of which is exposed and visible in the block
of the instrument)
Intonation Adjustment
To make adjustments:
1. Detune the guitar approximately 2 full steps
2. Break loose the neck dovetail bolts by half a turn
3. Make adjustment by accessing the intonation setscrew through the sound hole.Turning the setscrew clockwise will
cause the guitar to play flat, turning it counterclockwise the guitar will play sharp. Note that one full rotation of the set
screw will impact intonation by 2-3 cents
4. Ensure neck is fully seated
5. Tighten the dovetail clamping bolts to 25” lbs.
6. Tune to pitch and recheck intonation on strobe tuner
