Adjusting the tremolo attachment angle
The angle at which the tremolo is attached is adjusted by the
balance between the tension of the strings and the tension of the
tremolo springs installed in the back of the guitar body.
The tremolo will perform optimally when adjusted so that it is
approximately parallel with the surface of the guitar body.
1.
With the guitar tuned correctly, check the angle of the tremolo.
2.
If the tremolo is tilted forward, turn the spring adjustment
knob located on the back of the body toward the "plus"
direction to tighten the tremolo springs.
3.
If the tremolo is tilted toward the rear, turn the spring
adjustment knob toward the "minus" direction to loosen
the tremolo springs.
※
Because the balance of tension between the strings and the springs will
change each time you adjust the tension of the tremolo springs, adjusting
the tremolo angle in the fl oating state will affect the tuning. You'll need to
tune the guitar repeatedly while performing this adjustment.
Arm-up stopper
The SynchroniZR has an arm-up stopper feature. This feature disables the fl oating state by locking the
arm-up range of movement.
1.
Make sure that the tremolo is adjusted so that it is approximately parallel with the surface of
the guitar body.
2.
Remove the tremolo spring cover, and turn the arm-
up stopper knob so that the tip of the arm-up stopper
contacts the tremolo block.
3.
Once again make sure that that the tremolo is
approximately parallel with the surface of the guitar body,
and turn the spring adjustment knob several times in the
"plus" direction.
※ If the tremolo spring tension is too weak, the tremolo block will be
pulled by the strings, possibly causing the tuning to be unstable.
If you experience this problem while tuning, turn the spring
adjustment knob even farther in the "plus" direction.
String height adjustment
To adjust the string height, adjust the height of the entire tremolo
unit by using an Allen wrench (3 mm) to turn the stud bolts
located at the left and right of the tremolo unit. (It is not possible
to individually adjust the height of each string.)
