Adjusting the action
Adjust the height of the tremolo unit by turning the stud lock screws (Fig. 5 G) on either
side of the tremolo unit with a 3 mm Allen wrench. Note that it is not possible to adjust
the height of individual strings.
Adjusting the intonation
Remove the intonation adjustment bolts (Fig. 6 K) 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 (Fig. 5 H) with a 2 mm Allen
wrench, then turn the intonation adjustment screws to adjust the saddle position. Tune
the guitar and check the intonation. Repeat these adjustments until the required intona-
tion is reached. Fully tighten the saddle lock screws and put the intonation adjustment
screws into the bridge unit.
Replacing the strings
Loosen the pressure pad screws (Fig. 7 L) on the locking nut with a 3 mm Allen
wrench and remove the strings from the tuning machines. Loosen the string stopper
screw (Fig. 6 J) on the tremolo unit with a 3 mm Allen wrench and remove the string
from the saddle. Cut off the ball end of the new string with an end nipper or wire cutter
(Fig. 8). Insert the cut side of the new string between the saddle and the string holder
block. Tighten the string stopper screw to secure the string. Wind the string around
the tuning machine and tune to pitch. After tuning, tighten the pressure pad screw on
the locking nut.
Caution
Before you tune a string, ensure that the string stopper screw is firmly tight-
ened.
Fine tuning
After locking the strings with locking nuts, fine tuning of individual strings can be carried
out using fine tuners. To provide maximum allowance for fine tuning adjustment after
locking the strings, set the fine tuners (Fig. 5 F) to sit around the middle position of the
range of movement before tuning.
