ZR (ZERO RESISTANCE) TREMOLO
TREMOLO ARM
Loosen the screw cap, insert the arm
into the tremolo unit, and rotate it to
fasten it in place (Fig.8). Rotate the arm
to adjust it to the desired height. The
arm torque is adjusted by the tightness
of the screw cap. To remove the arm,
loosen the screw cap and rotate the
arm counter-clockwise (Fig.9).
FINE TUNING
Even after locking the locking nut, you can use the fine tuners (Fig.10 A) to
make fine adjustments to the tuning of each string.
You should adjust all of the fine tuners to the center of their adjustable
range before you lock the locking nut.
ADJUSTING THE ACTION
To adjust the entire tremolo unit up or down, use an Allen wrench to turn
the stud bolt (Fig.10 B) located at the left and right of the tremolo unit.
(This cannot be adjusted for each individual string.)
ADJUSTING THE INTONATION
Loosen the string stopper bolt of the locking nut (Fig.11). Remove the
intonation adjustment bolt (Fig.12 B) from within the bridge unit, fasten it
into the screw hole in the rear of the saddle, and tighten it so that the tip
of the bolt contacts the boss of the bridge unit. Loosen the saddle lock bolt
(Fig.10 C), and turn the intonation adjustment bolt to adjust the position of
the saddle. After completing the adjustment, tighten the saddle lock bolt
sufficiently to prevent the saddle from moving forward during tuning, and
store the intonation adjustment bolt inside the bridge unit.
REPLACING THE STRINGS
Loosen the string stopper bolt of the locking nut (Fig.11), completely
loosen the string at the tuning machine, use an Allen wrench to loosen the
string stopper bolt of the bridge saddle (Fig.12 A), and remove the old
string. Use wire cutters to remove the ball end from the new string as
shown in Figure 13, insert this end of the string into the bridge saddle,
fasten it firmly, and then tighten the string at the tuning machine. After
tuning, check the angle of the tremolo unit, and fasten the string stopper
bolt of the locking nut to finish the procedure.
ADJUSTING THE ZERO POINT SYSTEM
The Zero Point system makes it easier to tune a floating tremolo unit,
provides greater tuning stability after arming, and limits the tuning drift
that would otherwise occur when a string breaks.
*If the Zero Point system is not adjusted to the correct position it will not
function optimally, since it will either be completely floating, or the Zero
Point system and the string tension will be in balance. You must perform
this adjustment accurately.
