Using as a floating tremolo (Zero Point System deactivated)
The Edge-Zero and ZR2 tremolo can also be used as a normal floating tremolo by de-
activating the Zero Point System. While holding the arm up (with the tremolo block facing
away from the stop-rod (Fig. 5 C), remove the-stop rod and sub-spring (Fig. 6 F). The
angle of the tremolo that is kept in a floating state is adjusted by the balance between the
tension of the strings and the tension of the tremolo springs installed on the back side
of the guitar body. To maximize performance, set the tremolo so that it is approximately
parallel to the surface of the guitar body. To adjust the angle of the tremolo, turn the
spring adjustment knob (Fig. 4 B) on the back side of the guitar. If the tremolo is tilted
forward while the guitar is tuned correctly, turn the spring adjustment knob clockwise
to tighten the spring. If the tremolo is tilted backward, turn the spring adjustment knob
counterclockwise to loosen the spring.
When adjusting the tremolo angle in the floating state, the balance between the tension
of the strings and the tension of the tremolo springs changes each time the tension of the
spring is adjusted. Thus, adjustments should affect tuning. Make adjustments by tuning
the strings repeatedly.
Adjusting the action
Adjust the height of the tremolo unit by turning the stud lock screws (Fig. 7 H) on either
side of the tremolo unit with a 3 mm Allen key. Note that it is not possible to adjust the
height of individual strings.
Stud lock mechanism (Edge Zero tremolo)
The Edge Zero tremolo has a stud lock mechanism. The stud lock bolts (Fig. 8 L) are
packed in the accessory bag. Remove the tremolo unit and stud bolts (Fig. 7 H) from the
guitar. Install the stud lock bolts into the holes in the bottom of each stud bolt with the
adjustment holes for an Allen key facing up. To lock the stud bolt, insert a 2 mm Allen key
into the hole on the top of the stud bolt and turn the bolt clockwise (Fig. 8 K). The stud
lock bolt is locked when it touches the anchor bolt and cannot be turned any further.
Adjusting the intonation
Remove the intonation adjustment bolts (Fig. 9 N) housed in the bridge unit and tighten
them in the screw holes at the rear of the saddle until the end of each bolt touches the
wall of the bridge unit. Loosen the saddle lock screws with a 2 mm Allen key (Fig. 7 J),
turn the intonation adjustment screws to adjust the saddle position. Tune the guitar and
check the intonation. Repeat these adjustments until the required intonation is reached.
Fully tighten the saddle lock screws and put the intonation adjustment screws into the
bridge unit.
