STRING GAUGES
All guitars are set up at the factory with light gauge 009”- 042” strings
(7-string 009”- 054”). Different gauges of strings can result in the need
for string height, neck curvature, tremolo spring and intonation
readjustments.
Ibanez guitars feature four styles of locking tremolos. To identify which
tremolo is used on your guitar, locate the logo stamped either on the
bridge plate or the bridge tremolo block.
*Both Lo-Pro Edge and Edge tremolos have the “Edge” logo on the tremolo blocks.
*Adjustment of the 7-string tremolo is the same as the corresponding 6-string tremolo.
ADJUSTMENT
Lo-Pro Edge / Edge / Lo-TRS / TRS101
In the case of locking tremolos, 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 (F) 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 (F) and tune the string.
After checking the intonation, tighten the Pressure pad screw (D) on the
locking nut.
TRS505
In the case of TRS505 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. Remove the string through the
String holder hook (G). Thread new string
through the String holder hook (G) and tune
it. After checking the intonation, tighten the
Pressure pad screw (D) on the locking nut.
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.
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 (H) if the tremolo is forward dumped.
Loosen the screws (H) if the tremolo is up-
pulled. Retune the strings to the proper pitch
and check the angle.
Edge and Lo-Pro Edge tremolos have the
Block Lock System to lock the tremolo springs
on the tremolo block. Remove the Block Lock
when replacing the springs. Choose the
number and placement of the tremolo springs
according to the string gauge and the tremolo
angle as follows.
Loosen the Pressure pad screw (D) on the locking nut and loosen the
string to be adjusted. Loosen the Saddle lock screws (E) on the saddle to
be adjusted and adjust the saddle forward or backward.
Tighten the Saddle lock screw (E) and tune the string. After rechecking
the intonation, tighten the Pressure pad screw (D).
On the base plate there are two holes for each Saddle lock screw (C).
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.

TREMOLO ARM
Edge / Lo-Pro Edge
The tremolo arm can be inserted and removed very
easily. Insert the tremolo arm into the arm socket
and firmly push down until the arm snaps into
place. Both bushings should be completely hidden.
The rotation torque of the arm can be adjusted by
removing the bushings. To
further reduce the torque,
remove both bushings. To
replace the bushings, open
the new bushings at the split section and snap
them into place on the arm.
*After some time and use, it may impossible to secure
the arm even when both bushings are in place. If this
happens, replace the arm bushings with new ones.
Lo-TRS / TRS101 / TRS505
Insert the tremolo arm into the arm socket
and turn it clockwise until it stops. The
rotation torque of the arm can be adjusted by
turning the arm counterclockwise.
Lo-TRS and TRS tremolos are equipped with
a arm stop position screw located on the
bottom of the tremolo block and can be
adjusted by tightening the screw.
FINE TUNING
After locking the top lock, fine tuning the instrument can be done by
turning the fine tuning screws (A).
*To allow maximum fine tuning adjustment, it is recommended that the fine tuners be
set to the middle position before locking the nut.
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.
In the case of Edge and Lo-Pro Edge tremolos, the
Pivot studs(B) are locked internally by the Stud lock
screws(C). Always loosen the Stud lock screws (C)
before tightening the Pivot studs(B). After adjusting the
string height, tighten the Stud lock screws(C).
