ATTACHING THE TREMOLO ARM
① The tremolo arm employs a one-piece snap-in design with an adjustable torque cap. Insert the tremolo arm into the arm socket of the base plate.
② Tighten the torque adjustment cap to secure the tremolo arm. The tremo lo arm will become tighter as you tighten the torque adjustment cap.
TREMOLO ANGLE ADJUSTMENT / ZERO POINT SYSTEM ADJUSTMENT
・
Models not equipped with the zero point system
The tremolo attachment angle is adjusted by changing the balance between the string tension and the tension of the tremolo springs installed on the back of the guitar body. You’ll obtain the best performance by adjusting the tremolo arm 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, insert a Philips screwdriver through the slit in the tremolo spring cover on the back of the body, and tighten the screws to increase the tension of the tremolo springs.
③ If the tremolo is tilted toward the rear, loosen the screws to weaken the tension of 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, adjust ing the tremolo angle will aff ect the tuning. You’ll need to tune the guitar repeatedly while performing this adjustment.

Models equipped with the zero point system
The angle at which the tremolo is attached is adjusted by the balance between the tension of the strings and the zero point system installed on the back of the guitar body. The Edge-Zero 2 tremolo bridge is designed so that when the zero point system is correctly adjusted, the tremolo will be approximately parallel with the surface of the guitar body, and will perform optimally when in that 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.
TREMOLO SPRING / ZERO POINT SYSTEM
・
Models not equipped with the zero point system
When shipped from the factory, the guitar is set up with three tremolo springs installed in parallel.
If the balance of tension between the strings and the tremolo springs has changed signifi cantly, such as when you switch to a diff erent gauge of strings or use a dropped tuning, you may need to change the number of tremolo springs or change the way in which they are installed.
① Use a Philips screwdriver to remove the spring lock.
② If you want to increase the tension, install the outer two tremolo springs diagonally.
③ If you want to decrease the tension, remove the center tremolo spring.

If you want to install four or more tremolo springs, attach them using the screw holes that were being used to attach the spring lock. (It will no longer be possible to attach the spring lock.) Memo • Loosen the strings suffi ciently before you install or remove tremolo springs.
Be aware that if you remove all of the springs, the tremolo unit will detach from the guitar.
• To reattach the tremolo, insert the knife edge of the tremolo securely into the groove of the stud bolts, and then install the tremolo springs.

Models equipped with the zero point system
By disabling the zero point system you can 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 aff ected 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. You’ll need to tune repeatedly while making this adjustment.
STUD LOCK
The Edge-Zero2 tremolo bridge uses a stud lock mechanism.
① Insert an HEX key wrench (2 mm) through the hole in the top of the stud bolt.
② Turn the stud lock bolt clockwise, tightening it until it contacts the anchor nut and can no longer rotate.
※ The stud lock will be released when you loosen the stud lock bolt.
ADJUSTING THE ACTION
To adjust the height of the entire tremolo unit, use an HEX key wrench (3 mm) to turn the stud bolts located at the left and right of the tremolo unit. (It is not possible to make adjustments for each string individually.) Memo • Before you tune, make sure that the string stopper bolts are fi rmly tightened.

ADJUSTING THE INTONATION
① Use an HEX key wrench (3 mm) to loosen pressure pad bolts of the locking nut, and loosen the strings suffi ciently.
the ② Use an HEX key wrench (2 mm) to loosen the saddle lock bolts, and adjust the saddle position.
※ Before checking the intonation, fi rmly tighten the saddle lock bolts and tune the guitar correctly. When you’ve fi nished making adjustments, tighten the saddle lock bolts and the pressure pad bolts of the locking nut.
REPLACING THE STRINGS
① Use an HEX key wrench (3 mm) to loosen the pressure pad bolts of the locking nut, and remove the string from the tuning peg.
② Use an HEX key wrench (3 mm) to loosen the string stopper bolt of the tremolo unit; then pull the string out of the saddle and remove it.
③ Use wire cutters to cut off the ball end of the new string.
④ Insert the tip of the string from which you cut off the ball end between the saddle and the string holder block, and tighten the string stopper bolt to fasten the string.
⑤ Wind the string onto the tuning peg, and tune it.
⑥ When you’ve fi nished tuning, tighten the pressure pad bolts of the locking nut.
※ On tremolo bridges not equipped with the zero cross system, removing all strings at the same time will cause the tremolo attachment angle to change signifi cantly, so we recommend that you replace the strings one at a time. If you remove all strings at the same time, tuning will be easier if you wedge a piece of cloth below the tremolo to secure it so that the tremolo attachment angle won’t change signifi cantly.
EN Memo • Before you tune, make sure that the string stopper bolts are fi rmly tightened.
FINE TUNING
Even after you’ve used the locking nuts to lock the strings, you can use the fi ne tuners to fi ne-tune each string.
The range of adjustment after the strings are locked will be widest if you leave all fi ne-tuning bolts near the center of their adjustable range before you tune.
