ANGLE ADJUSTMENT / ZERO POINT SYSTEM ADJUSTMENT
The tremolo attachment angle is adjusted by changing the balance between
the string tension and the tension of the zero point system installed on
the back of the guitar body. The ZR tremolo bridge is designed so that the
tremolo will be approximately parallel with the surface of the guitar body
when the zero point system is adjusted correctly, and will perform optimally
in this state. When the zero point system is correctly adjusted, the stop rod
will be in fi rm contact with the tremolo block and the stop rod will be touching
the stopper.
1 With the guitar tuned correctly, check the zero point system.
2 If the stop rod is not touching the stopper (i.e., if the tremolo block is
pushing up the stop rod), turn the spring adjustment knob located on the
back of the body toward the "plus" direction to tighten the main spring.
3 If the tremolo block is not in fi rm contact with the stop rod (i.e., if the
tremolo is tilted toward the rear), turn the spring adjustment knob toward
the "minus" direction to loosen the main spring.
DISABLING THE ZERO POINT SYSTEM (USING THE UNIT AS A
DISABLING THE ZERO POINT SYSTEM (USING THE UNIT AS A CONVENTIONAL FLOATING
By disabling the zero point system you can also use the unit as a conventional fl oating bridge.
When the zero point system is disabled, the angle at which the tremolo is attached will be adjusted by the balance
between the tension of the strings and the tension of the main springs attached to the tremolo block.
For optimal performance, adjust the tremolo so that it is approximately parallel with the surface of the guitar body.
1 While holding the arm in the upward position (i.e., with the tremolo block
away from the stop rod), remove the stop rod and the sub-spring.
2 With the guitar tuned correctly, check the angle of the tremolo.
3 If the tremolo is tilted toward the front, turn the spring adjustment knob
toward the "plus" direction to tighten the main spring.
4 If the tremolo is tilted toward the rear, turn the spring adjustment knob
toward the "minus" direction to loosen the main spring.
※
The tuning will be affected when you adjust the tremolo angle with the zero point system disabled, because the
balance between the tension of the strings and the springs will change each time you adjust the tension of the
tremolo springs. Youʼll need to tune repeatedly while making this adjustment.
