REPLACING THE STRINGS
ACT tremolo allow two styles of string installation.
1) The strings are installed by putting the ball end into the string slot and
hooking the ball end below the string catch at the rear of the tremolo
unit. (Figure 1)
(Figure 1)
2) The strings are installed by putting the ball end into the string slot and
hooking the ball end in the string catch at the bottom of the tremolo unit.
This increases string tension and adds sustain. (Figure 2)
(Figure 2)
TREMOLO ARM INSTALLATION
The tremolo arm can be inserted and removed very easily. Insert the arm
into the armhole on the tremolo base plate. Pull up on the arm to remove it.
ADJUSTING THE TREMOLO SPRINGS
ACT Tremolo is designed to function optimally when it is installed
approximately parallel with the surface of the guitar body. The angle at
which the tremolo is attached can be adjusted by changing the length of
the tremolo springs under the tremolo unit. Use a Philips (+) screwdriver
to turn the tremolo tension adjustment screws to adjust the length of the
tremolo springs. (Figure 3, (B)) If the tremolo is tilted forward toward the
neck of the guitar, turn the screws clockwise to tighten the springs.
Conversely, if the tremolo is tilted backward away from the neck, turn
the screws counter-clockwise to loosen the springs. Tune the guitar
acctually, re-check the angle of the tremolo, and repeat the adjustment
until the tremolo angle is correct.

ADJUSTING THE ACTION
To adjust the entire tremolo unit up or down, use a 3.0mm Allen wrench
to turn the stud bolt (Figure 4, (C)) located at the left and right of the
tremolo unit. (This cannot be adjusted for each individual string.)
ADJUSTING THE INTONATION
Use a 2.0mm Allen wrench to loosen the saddle lock screws (Figure 4,
(D)) of each saddle, and move the saddle. Firmly tighten the saddle lock
screws, tune the guitar, and then check the intonation. Repeat these
adjustments until the intonation is correct.

ARM ROTATION TORQUE
The rotation torque of the arm can be adjusted by raising the tremolo
and inserting a 2.0mm Allen wrench in the screw (Figure 3, (A)) on the
tremolo block. Turning this screw clockwise will tighten the arm torque
and turning the screw counter clockwise will loosen the arm torque.
