ACT TREMOLO
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.
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.
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.
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 (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.
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. (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 (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 (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.
