ILT
ADJUSTING THE TREMOLO SPRING
The tremolo springs adjust the
tremolo angle by tightening or
loosening the tremolo tension. To
adjust tremolo angle, locate the
adjustment screws in the rear
tremolo cavity. The tremolo system
when in tune should sit parallel to
the surface of the guitar as follows.
If the tremolo system is not sitting
parallel to the surface of the guitar, remove the tremolo cavity cover
plate and tighten the Tremolo tension adjustment screws if the tremolo
is forward dumped. Loosen the screws if the tremolo is up-pulled.
Retune the strings to the proper pitch
and check the angle. Choose the number
and placement of the tremolo springs
according to the string gauge and the
tremolo angle.
REPLACING THE STRINGS
In the case of EDGE III tremolo, replace the
strings one by one. Removing all the old strings
at once will release the tension on the tremolo
and change the tremolo angle “up-pull.” Loosen
the Pressure pad screw (D) on the locking nut
and loosen the string to be replaced. Loosen the
String stopper screw (G) and remove the string
from the saddle. Cut off the ball end of new
string as shown on the illustration and insert the cut side of new string
between the saddle and the String holder block.Tighten the String
stopper screw (G) and tune the string. After checking the intonation,
tighten the Pressure pad screw (D) on the locking nut.
ADJUSTING THE STRING HEIGHT
The height adjustment of the tremolo can be
raised or lowered by adjusting the pivot studs
(B) that the tremolo mounts on. These are
located at either side of the front of the bridge.
Clockwise lowers the tremolo and counter
clockwise raises the tremolo.
TREMOLO ARM INSTALLATION
The tremolo arm can be inserted and removed
very easily. Insert the arm into the armhole on
the tremolo base plate. Pull up on the arm to
remove it.
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).
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.
TREMOLO ARM INSTALLATION
The tremolo arm can be inserted and
removed very easily. Insert the arm into
the armhole on the tremolo base plate. Pull
up on the arm to remove it.
ADJUSTING THE INTONATION
Loosen the Pressure pad screw (D) on the
locking nut and loosen the string to be adjusted.
Loosen the Saddle lock screws (F) on the saddle
to be adjusted and adjust the saddle forward or
backward. Tighten the Saddle lock screw (F)
and tune the string. After rechecking the
intonation, tighten the Pressure pad screw (D).
EDGE III
ADJUSTING THE TREMOLO SPRING
The tremolo springs adjust the tremolo
angle by tightening or loosening the
tremolo tension. To adjust tremolo
angle, locate the adjustment screws in
the rear tremolo cavity. The tremolo
system when in tune should sit parallel
to the surface of the guitar as follows.
If the tremolo system is not sitting parallel to the surface of the guitar,
remove the tremolo cavity cover plate and tighten the Tremolo tension
adjustment screws if the tremolo is forward dumped. Loosen the screws
if the tremolo is up-pulled.Retune the
strings to the proper pitch and check the
angle. Choose the number and placement
of the tremolo springs according to the
string gauge and the tremolo angle.
ADJUSTING THE ACTION
To adjust the entire tremolo unit up or down,
use an Allen wrench to turn the stud bolt (E)
located at the left and right of the tremolo
unit. (This cannot be adjusted for each
individual string.)
FINE TUNING
Even after locking the locking nut, you can use
the fine tuners to make fine adjustments to the
tuning of each string. You should adjust all of
the fine tuners (C) to the center of adjustable
range before you lock the locking nut.
ARM ACTION
The tremolo arm action can be adjusted by
using a 3.0mm Allen wrench on the screw (B)
of the tremolo screw.
ARM ROTATION TORQUE
The rotation torque of the arm can be adjusted
by raising the tremolo and inserting a 1.5mm
Allen wrench in the screw (A) on the tremolo
block, turning this screw clockwise will
tighten the arm torque and turning the screw
counter clockwise will loosen the arm torque.
ADJUSTING THE INTONATION &
THE STRING HEIGHT (FAT 6)
The intonation can be adjusted by
adjusting the saddle forward or
backward using a philips(+) head
adjustment screw at the rear of the
bridge. String height is controlled by
raising or lowering the small allen
screws using a wrench on either side
of the saddle.
TREMOLO ARM INSTALLATION
The tremolo arm can be inserted and
removed very easily. Insert the arm
into the armhole on the tremolo base
plate. Pull up on the arm to remove it.
ARM ROTATION TORQUE
The rotation torque of the arm can be
adjusted by raising the tremolo and
inserting a 1.5mm Allen wrench in
the screw (A) on the tremolo block,
Turning this screw clockwise will
tighten the arm torque and turning
the screw counter clockwise will
loosen the arm torque.
ADJUSTING THE STRING HEIGHT (FAT20/FAT10/SAT10)
The height adjustment of the tremolo can be raised or lowered by
adjusting the pivot studs (C) that the tremolo mounts on. These are
located at either side of the front of the bridge. Clockwise lowers the
tremolo and counter clockwise raises the tremolo.
ADJUSTING THE STRING HEIGHT (SAT PRO)
To adjust the action of each
string, use a 1.5 mm Allen
wrench to turn the screw on the
saddle (C). The overall height
can be adjusted on either side
of the SAT PRO tremolo unit. To
adjust the height, use a 3 mm
Allen wrench to turn the stud (D)
located on either side of the
unit. Use caution when
adjusting the height of the entire tremolo unit; adjust both sides to the
same height to ensure optimum tremolo operation.
FAT/SAT (expect FAT6)
ADJUSTING THE TREMOLO SPRING
A standard tremolo can be adjusted
so that the pitch can be raised when
the tremolo arm is pulled up to
loosen the tremolo springs located
under the tremolo cavity on the back
of the guitar. One disadvantage of
this procedure is that it can cause
the pitch to go sharp if string breaks.
To remedy this, adjust the tremolo
plate so it sits flush on the body by
tightening the tremolo springs.
Choose the number and
placement of the tremolo
springs according to the string
gauge and the tremolo
adjustment .
FLOATING PARALLEL
REPLACING THE STRINGS
To replace strings, thread the new
strings through the string holes
located on the back of the guitar. The
strings are then threaded through the
tremolo block and up and over the
saddle.
FAT/SAT TREMOLO

ARM ROTATION TORQUE
The rotation torque of the arm can be
adjusted by raising the tremolo and
inserting a 2.0mm Allen wrench in
the screw (A) on the tremolo block,
Turning this screw clockwise will
tighten the arm torque and turning
the screw counter clockwise will
loosen the arm torque.
FINE TUNING
Even after locking the locking nut,
you can use the fine tuners to make
fine adjustments to the tuning of
each string.
You should adjust all of the fine
tuners (C) to the center of their
adjustable range before you lock the
locking nut.
ARM ACTION
The tremolo arm action can be
adjusted by using a 2.0mm Allen
wrench on the screw (B) of the
tremolo block.
ADJUSTING THE ACTION
To adjust the entire tremolo unit up
or down, use an Allen wrench to turn
the stud bolt (E) located at the left
and right of the tremolo unit. (This
cannot be adjusted for each
individual string.)
EDGE PRO II TREMOLO
REPLACING THE STRINGS
The EDGE-PRO II tremolo will accommodate
either strings from which the ball end has
been cut, or conventional strings from
which the ball end has not been cut.
To remove a string, use a 3 mm Allen
wrench to loosen the pressure pad screw of
the locking nut (Fig.1), remove the string
from the tuning machine, and use a 3 mm
Allen wrench to loosen the string stopper
screw of the saddle (Fig.2). Turning this
counter-clockwise will automatically retract
the holder block, so loosen the string stopper
screw all the way until the holder block
stops retracting. Remove the old string,
insert approximately 3 cm of the new string
with ball end into the saddle, and while
making sure that the string is positioned in
the center of the saddle, tighten the string
stopper screw (Fig.2). Turning this clockwise
will automatically advance the holder block,
so after making sure that the string is firmly
fastened, wind the string around the tuning
machine post, tune it, and then tighten the
pressure pad of the locking nut.
When installing a wound string from which the ball end has been cut off,
you can leave the overwound portion of the winding intact in order to
prevent the winding from loosening. Insert approximately 1~3 cm of the
tip into the saddle, and install the string in the same way as a
conventional string from which the ball end has not been cut off.
Since the attachment angle of the tremolo will change significantly if all
strings are removed at once, you should replace the strings one at a time.
On the bottom of each saddle there is a guide stopper that indicates the
length of string to be inserted. The appropriate length will be inserted if
you insert the string until the tip contacts this guide.
If a string breaks at the saddle, it may fall into the tremolo cavity when
you loosen the string stopper screw. Remove the broken string either by
detaching the tremolo spring cavity cover plate from the back of the
guitar, or from the opening in the cover plate. If the broken spring
remains in the saddle, remove it from above.
Note: Before you tune a string, make sure that the string stopper screw is firmly tightened.
Note: To prevent the string stopper screw from falling out, do not loosen it more than three
turns after the holder block has stopped retracting.
ADJUSTING THE INTONATION
Before you adjust the intonation, use a 3 mm Allen wrench to loosen the
pressure pad screws (G) of the locking nut so that the strings are
released. Use a 2 mm Allen wrench to loosen the saddle lock screws (F)
of each saddle, and move the saddle. Firmly tighten the saddle lock
screws, tune the guitar, and then check the intonation. Repeat these
adjustments until the intonation is correct, and then tighten the pressure
pad screws of the locking nut.
You may install each saddle lock screw in either the forward or rear
position, depending on the position of the saddle.
The unit is designed so that the fine tuning screw will not operate if the
position of the saddle extends beyond the front edge of the base plate.
Note: When loosening the saddle lock screws, you must loosen the strings sufficiently before
making adjustments.
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.

(ZERO RESISTANCE)
TREMOLO
TREMOLO SPRINGS
The EDGE-PRO II tremolo is designed to
function optimally when it is installed
approximately parallel with the surface
of the guitar body (Fig.4). The angle at
which the tremolo is attached can be
adjusted by changing the length of the
tremolo springs inside the tremolo spring
cavity in the back of the guitar body.
Working through the adjustment holes in
the tremolo spring cavity cover plate, use
a Philips (+) screwdriver to turn the
tremolo tension adjustment screws to
adjust the length of the tremolo springs.
If the tremolo is tilted forward toward the
neck of the guitar (Fig.5), turn the screws
clockwise to tighten the springs.
Conversely, if the tremolo is tilted
backward away from the neck (Fig.6),
turn the screws counter-clockwise to
loosen the springs. Tune the guitar
accurately, re-check the angle of the
tremolo, and repeat the adjustment until
the tremolo angle is correct. The EDGE-
PRO II tremolo is designed to function
optimally when three springs are
tensioned equally with a 0.009" gauge
set of strings installed. If you replace the strings with a different gauge set,
you can adjust the tremolo angle by changing the number of springs or the
way in which the springs are installed.
Loosen all strings before you add or remove a tremolo spring.
The EDGE-PRO II tremolo uses a block lock mechanism to fasten the
tremolo springs to the block. Before you change the number of springs or
the way in which they are installed, use a Philips (+) screwdriver to
remove the block lock (Fig.7).
NOTE: If you want to install four or five tremolo springs, insert the springs into the block nut
attachment screw holes. (In this case, it will not be possible to attach the block 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.

FINE TUNING
After locking the top lock, fine tuning the instrument can be done by
turning the fine tuning screws (A).
REPLACING THE STRINGS
In the case of Lo-TRS II tremolo, replace the
strings one by one. Removing all the old strings
at once will release the tension on the tremolo
and change the tremolo angle “up-pull.”
Loosen the Pressure pad screw (C) on the
locking nut and loosen the string to be
replaced. Loosen the String stopper screw (E)
and remove the string from the saddle. Cut off
the ball end of new string as shown on the illustration and insert the cut
side of new string between the saddle and the String holder block .
Tighten the String stopper screw (E) and tune the string. After checking
the intonation, tighten the Pressure pad screw (C) on the locking nut.
* To allow maximum fine tuning adjustment, it is recommended that the fine tuners be set to the middle position
before locking the nut.
ADJUSTING THE INTONATION
Loosen the Pressure pad screw (C) on the
locking nut and loosen the string to be adjusted.
Loosen the Saddle lock screws (D) on the saddle
to be adjusted and adjust the saddle forward or
backward. Tighten the Saddle lock screw (D)
and tune the string. After rechecking the
intonation, tighten the Pressure pad screw (C).
* On the base plate there are two holes for each Saddle lock screw. These allow the user to change string gauges
while allowing the maximum saddle movement. If the intonation cannot be adjusted because the saddle needs
to be set back further, remove the intonation screw and insert it into the hole located further back on the bridge
plate.

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.
<NOTE>
INTONATION ADJUSTMENT
(SAT PRO)
To adjust the intonation, use a 1.5 mm
Allen wrench to turn the screw located
at the rear of the saddle (E). Turn the
screw clockwise to move the saddle

SWITCHING TO FLOATING OPERATION
By stopping the Zero Point system from
functioning, you can make the tremolo
float completely. While holding the arm
up, remove the stop rod and sub spring.
With the guitar tuned correctly, use the
main spring adjustment knob (Fig. 14E)
to adjust the angle of the tremolo unit. If
the tremolo unit is tilted forward toward
the neck, turn the spring adjustment
knob in the plus (+) direction.
Conversely, if the tremolo unit is tilted
backward away from the neck, turn the
spring adjustment knob in the minus (-)
direction.
*You will need to tune repeatedly during
the process of adjusting the tremolo
angle in the floating state, since the
tuning will drift each time you adjust the
main spring adjustment knob.
