ZR TREMOLOThe ZR Tremolo is a double locking tremolo featuring the Zero Point System that keepsthe tremolo unit flat (at the zero point). This system eliminates the hassle of tuning, whichis a shortcoming of a floating tremolo, providing a more comfortable playing experience.Furthermore, the supporting point is equipped with a high-precision built-in ball bearing,which realizes smooth arming.Attaching the tremolo armThe tremolo arm is a plug-in type with a torque adjustment cap incorporated into the armunit. Insert the tremolo arm into the arm socket of the base plate, and then tighten thetorque adjustment cap (Fig. 1) to fix the tremolo arm in place. You can adjust the tremoloarm torque by tightening/loosening the torque adjustment cap. Turning the cap clockwisewill tighten the arm torque, and turning it counterclockwise will loosen the arm torque.Adjusting tremolo angle and Zero Point SystemThe angle of the tremolo is adjusted by the balance between the tension of the stringsand the zero point system installed on the back side of the guitar body. The ZR tremolois designed so that by correctly adjusting the Zero Point System, the tremolo unit sitsroughly parallel to the surface of the guitar body. This ensures optimal performance. Tun-ing is completed when the Zero Point System is adjusted to the correct position. If thetremolo is roughly parallel to the surface of the body, the stop rod contacts the tremoloblock and the stopper.To adjust the angle of the tremolo, turn the spring adjustment knob (Fig. 2 A) on the backside of the guitar. If the stop rod (Fig. 3 B) does not contact the stopper (Fig. 3 C) (or thetremolo is tilted forward) when the guitar is correctly tuned, turn the spring adjustmentknob clockwise to tighten the spring. If the tremolo block (Fig. 3 D) does not contact thestop rod (or the tremolo is tilted backward), turn the spring adjustment knob counter-clockwise to loosen the spring.Using as a floating tremolo (Zero Point System deactivated)The ZR tremolo can also be used as a normal floating tremolo by deactivating the ZeroPoint System. While holding the arm up (with the tremolo block facing away from thestop rod), remove the stop rod (Fig. 3 B) and sub spring (Fig. 4 E). Adjust the angle ofthe tremolo that is in a floating state by adjusting the balance between the tension ofthe strings and the tension of the tremolo springs installed on the back side of the guitarbody. Setting the tremolo so that it is approximately parallel to the surface of the guitarbody will ensure optimal performance. To adjust the angle of the tremolo, turn the springadjustment knob (Fig. 2 A) on the back side of the guitar. If the tremolo is tilted forwardwhile the guitar correctly tuned, turn the spring adjustment knob clockwise to tighten thespring. If the tremolo is tilted backward, turn the spring adjustment knob counterclock-wise to loosen the spring.When adjusting the tremolo angle that is in a floating state, the balance between the ten-sion of the strings and the tension of the tremolo springs changes each time the tensionof the spring is adjusted, Thus, adjustments should affect tuning. Make adjustments bytuning the strings repeatedly.Fig. 1AFig. 2DBCFig. 3EFig. 4
