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 tremolo

arm will become tighter as you tighten the torque adjustment cap.

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.
