(Fig. ) * The “Tremolo Unit Holder” helps to keep the tremolo unit stable and horizontal for easy string change and re-tuning. ■ Adjusting the torque of the tremolo arm Set “Tremolo Unit Holder” To adjust the torque of the tremolo arm, tighten or loosen the screw on the side of the “arm base” with a hexagonal wrench. (Fig. ) * Attach the tremolo arm before adjusting the torque. Adjust the arm torque Tremolo Unit Holder Loosen Arm Base Tighten * When setting the “Tremolo Unit Holder”, Adjust the height by rotating the head so the tremolo unit is parallel to the top of the guitar body.

(Fig. ) ) and rotate the lever to Adjust the lever position English Install new strings Pull out Adjust the angle 5 2 Tune the strings to the correct pitch with the tuning machines, leaving the locking lever up. (not returning to the original position) (Fig. ) Return the locking levers on the FC tremolo to the original position to lock the strings. (Fig. ) Lock the strings at bridge * Be sure that the strings stay in the string slots of the bridge saddles. * The “Fine Tuners” should be in the middle of their travel range. Fine Tuner Tune the strings to the pitch Fine Tuner Locking Lever 6 7 Remove the “Tremolo Unit Holder” from the tremolo arm. Fine tune the each strings with the “Fine Tuners” on the FC tremolo.

(Fig. ) a) If the fretted tone at the 12th fret is higher in pitch than the harmonic tone at the 12th fret, rotate the intonation screw clockwise to move the bridge saddle backwards. * All the string heights can be set properly by adjusting the two bolts. English Adjust the location of the bridge saddle with the hexagonal wrench. (Fig. ) b) If the fretted tone at the 12th fret is lower in pitch than the harmonic tone at the 12th fret, rotate the intonation screw counter-clockwise to move the bridge saddle forwards. Adjust string height Move the bridge saddle Lower action Bridge Saddle Higher action a) Backward b) Forward ■ Intonation adjustment 1 To adjust the intonation of each string, pull up the locking lever of the FC tremolo (Fig. ) and loosen the screw inside the bridge saddle. (Fig. ) 3 4 Tighten the screw inside the bridge saddle. (Fig. ) Return the locking lever of the FC tremolo to the original position. (Fig. ) Unlock the bridge saddle Tighten Loosen Part 5 : Adjusting the Truss Rod 1 Loosen two screws of the truss rod cover with the Phillips head screw driver. (Fig. ) 2 Rotate the truss rod nut with the screw driver. (Fig. ) * The curvature of the neck should be slightly concave. * Make any adjustments gradually.
