...
EDGE III TrEmolo
The Edge III Tremolo is an Ibanez original tremolo that features fine-tuners, much like
the Lo-Pro Edge, and provides extraordinary strength and tuning stability. The Edge III
Tremolo offers features that are required for a double-locking tremolo, and successfully
combines Ibanez’s original ideas with its unique appearance.
Attaching the tremolo arm
The tremolo arm can be inserted and removed easily. Be sure to insert the tremolo arm
into the arm socket (Fig. 1 A) and push down firmly until the arm snaps into place. To
adjust the torque of the tremolo arm, use a 2 mm Allen key to turn the torque adjustment
screw (Fig. 1 B) through the adjustment hole in the side of the base plate attached to
the back of the arm socket. Turning the screw clockwise will tighten the arm torque, and
turning the screw counterclockwise will loosen the arm torque. To adjust the height of
the arm, remove the tremolo spring cover from the back of the guitar and turn the height
adjustment screw (Fig. 1 C) attached to the bottom of the tremolo block with a 3 mm Allen key. Tightening the screw clockwise will raise the height.
Caution
The Edge III Tremolo has two torque adjustment screws for the tremolo arm:
one is at (Fig. 1 B) and the other is under height adjustment screw (Fig. 1 C).
The adjustment screws are factory adjusted. If adjustment is required, be sure
to remove the tremolo from the guitar before making adjustments.
The Ibanez EGEN8 Herman Li Signature Ibanez EGEN8 has a screw in tremolo arm.
Insert the tremolo arm into the tremolo unit and rotate it to fasten it in place. The method
of adjusting the torque of the tremolo arm is the same as for Edge III.
Caution
Check that the screw (Fig. 1 C) securing the tremolo arm is not loose before
attaching it.
Adjusting the tremolo angle
The angle of the tremolo 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.
Setting the tremolo so that it is approximately parallel to the surface of the guitar body
will ensure optimal performance (Fig. 2). To adjust the tremolo angle, insert a Philips
screwdriver into a slit in the tremolo spring cover attached to the back of guitar body
and turn the screw of the tremolo spring hook (Fig. 3). With the guitar tuned accurately,
if the tremolo unit is tilted forward, turn the screws clockwise to tighten the springs. If the
tremolo unit is tilted backward, turn the screws counterclockwise to loosen the springs.
When adjusting the tremolo angle, 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. If the string tension significantly changes after the strings have been changed
to a different gauge, it is sometime necessary to change the number of springs or the
way in which the springs are installed.

Adjusting the action
Adjust the height of the tremolo unit by turning the stud lock screws (Fig. 4 E) 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.
Adjusting the intonation
Loosen the pressure pad screws (Fig. 5 H) on the locking nut with a 3 mm Allen key and
fully loosen the strings. Loosen the saddle lock screw (Fig. 4 F) with a 2 mm Allen key and
adjust the saddle position. Firmly tighten the saddle lock screw (Fig. 4 F), tune the guitar,
and then check the intonation. Repeat these adjustments until the required intonation is
reached, and then tighten the pressure pad screws (Fig. 5 H) in the loc king n uts.
Caution
When loosening the saddle lock screws, you must fully loosen the strings before making adjustments.
replacing the strings
Loosen the pressure pad screws (Fig. 5 H) on the locking nut with a 3 mm Allen key and
remove the strings from the tuning machines. Loosen the string stopper screw (Fig. 4 G)
on the tremolo unit with a 3 mm Allen key and remove the string from the saddle. Cut off
the ball end of the new string with an end nipper or wire cutter (Fig. 6). Insert the cut side
of the ne w 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
Since the angle of the tremolo will change significantly, if all strings are removed at once, you should replace the strings one at a time. To remove all
strings at the same time, tuck a piece of cloth behind the tremolo so that the
tremolo unit sits parallel to the surface of the body. This can make tuning
easy.
Before you tune a string, ensure that the string stopper screw is firmly tightened.
Fine tuning
After locking the locking nut, fine tuning of each string can be carried out by using fine
tuners. To allow maximum fine tuning adjustment, it is recommended that the fine tuners
(Fig. 4 D) be set to the middle position of the range of the movement before tuning.

GIBRALTAR CUSTOM BRIDGE
(for a guitar with 6/7 strings)
The Gibraltar custom bridge is designed to enable efficient transfer of string vibration to
the body by securing the bridge body onto the sustain block embedded in the body.
Adjusting the action
Loosen the bolts (Fig. 1 A) on the right and left ends of the bridge unit for fixing the
bridge, and adjust the height of the bridge unit by turning the four height adjustment
screws (Fig. 1 B) on the upper section of the bridge with a 2 mm Allen wrench. Note that
it is not possible to adjust the height of individual strings. After completing adjustment,
tighten the bolts for fixing the bridge.
Adjusting the intonation
Loosen the saddle lock screws (Fig.1 C) with a 2 mm Allen wrench, then turn the intonation adjustment screw (Fig.1 D) with a 2 mm Allen wrench to adjust the saddle position.
Tune the guitar and check the intonation. Repeat these adjustments until the required
intonation is reached, and then tighten the saddle lock screws.
Caution
When adjusting the intonation, be sure to fully loosen the saddle lock bolts
beforehand using a 2 mm Allen wrench. Otherwise, damage may occur.
Replacing the strings
Install strings by threading them from the back of the guitar body through the string anchoring ferrules. After making some string wraps, check that the string rests in the slot
at the center of the saddle.

GIBRALTAR STANDARD BRIDGE
Adjusting the action
One of the features of the Gibraltar standard bridge is that the saddle height can be adjusted
individually. To adjust the height of each saddle, turn the adjustment screws (Fig. 1 A) with a
1.5 mm Allen wrench.
Adjusting the intonation
To adjust the saddle position, turn the intonation adjustment screws (Fig. 1 B) on the rear
section of the bridge with a 2.5 mm Allen wrench. Tune the guitar and check the intonation. Repeat these adjustments until the required intonation is reached.
Replacing the strings
There are two methods available for replacing the strings: installing strings through the
string-retainer ferrule, and hooking the ball-end onto the rear of the tailpiece (Fig. 2 C).

ADJUSTING THE NECK
The neck bears the tension of the strings. The curvature of the neck is subtly affected not
only by the tuning state and string gauge, but also by changes in temperature and humidity. For this reason, the neck contains an internal truss rod that allows the curvature
to be precisely adjusted.
Tune the strings accurately, hold the guitar in playing position, then press the first string
at the first fret and at the fret that is nearest to the point where the neck joins the body,
as shown in Fig. 1. (It will be more convenient to use a capo at the first fret.) Measure
the gap between the string and fret at the eighth fret. Do the same for the sixth (lowest)
string. For each string, the gap should be in the range of 0.3-0.5 mm (a slight bow in
the neck). Although symptoms may vary depending on the type of neck and on how the
neck is joined to the body, problems such as excessive string height, string buzz for high
notes, or intonation difficulties may occur due to an excessively bowed neck (Fig. 2 A),
which will cause this gap to be larger. Conversely, problems such as insufficient string
height, string buzz for low notes, or muted notes may be due to a neck that is bowed
in the reverse direction (Fig. 2 B), which will cause this gap to be smaller. Try to refrain
from simply making a visual judgment. Rather, determine the problem based on the
symptoms that occur, and make the appropriate adjustment. The truss rod nut is located
at the headstock end of the neck. Using the Allen wrench or socket wrench included with
the guitar, tighten the nut toward the right (Fig. 3 C) if you want to bend the neck in the
convex direction, or loosen the nut toward the left (Fig. 3 D) if you want to bend the neck
in the concave direction. Make adjustments in quarter-turns, alternating steps of tuning
and adjustment.
Caution
You must exercise appropriate care when adjusting the neck. If the truss rod
nut does not turn as you expect, or if you are unable to make adjustments
accurately, do not attempt to force the adjustment; contact your dealer or the
Ibanez company.
PICKUPS
By adjusting the pickup height, you can make fine adjustments to the volume and tone. For
a commonly used pickup height, adjust the adjustment screws (Fig. 4 E) on both sides of
the pickup with a Phillip screwdriver to create a space of 2-5 mm between the pickup/pole
piece and the strings pressed at the last fret. Howe v er, this adjustment will depend on your
playing style or on the characteristics of y our amp, so you should make this adjustment while
listening to the actual sound. For pickups of the type that allows the pole piece to be adjusted,
you can correct the volume balance for each string. (Note that y ou can only make adjustment
within a given adjustment range.) Depending on the type of pole piece, use either an Allen
wrench (Fig. 4 F) or a slot head screwdriver, whichever is suited for the pickups .
The volume will increase as the distance between the pickup and string decreases, but if
the spacing is too close, you may get cracked sounds or the string may buzz due to the
magnetic field of the pickup. Conversely, increasing the distance between the string and
pickup will produce a clearer sound with less distortion, but the high-frequency range
may be attenuated and the volume may drop.
For the LZ series of Ibanez active pickups, the pickup characteristics and equalizer balance are adjusted according to the model hosting them. It is designed to enable correct
action to be taken by making correct combinations of the pickups installed on the guitar
and the equalizer to be used. No other combination will work. Do not use this series with
LZ pickups used with some other models or in conjunction with active pickups produced
by other manufacturers. This is also applicable to equalizer selection.

BATTERY
If your guitar has a built-in preamp or equalizer and requires a battery, you will need to
replace the battery when you notice that the volume has decreased or the sound has
become distorted. The battery is housed in a battery compartment or within the control
cavity. (The location may differ depending on the model of the guitar.) Depending on the
model, either 006P (9 V) battery or two AA (1.5 V x 2) batteries are used. When replacing the battery, check the orientation carefully to place it in the battery compartment or
control cavity in the correct orientation. For a guitar that requires two batteries, do not
mix old and new or alkaline and manganese batteries together. Also, do not use a battery
whose voltage or shape is different from that of the initially installed one.
For a guitar that requires a battery (batteries), the output jack also functions as a power
switch, and the power will turn on when you insert a plug into the output jack. To prevent
battery power leakage and depletion, remove the plug from your guitar if you will not be
using it for an extended period of time. To prevent your amp or other equipment from being damaged when you plug in your guitar, turn off the power of your equipment or turn
down the volume before you make connections.
Caution
The battery shipped with the guitar is for testing.
ADJUSTING THE INTONATION
(STRING lENGTH)
The fret position is set according to a calculation of the correct musical scale existing under
certain conditions, referring to the scale from the nut to the bridge. However, conditions under
which the guitar is played greatly vary depending on the thickness of strings, neck condition,
and tuning. In order to correct subtle interval diversions arising from these differences, you will
need to carry out fine adjustment for the string length (intonation adjustment). When replacing
with new strings, or when adjusting the neck, be sure to adjust intonation.
After completing adjustment of the neck or each section of the strings on the higher
side, you should perform accurate tuning (use of a tuning meter is recommended). Hold
it in playing position, and compare the pitch of the string pressed down at the 12th fret
with the harmonic played at the 12th fret. If the pitch played at the 12th fret is lower than
the harmonic, move the bridge saddle forward (Fig. 5 G) to shorten the string length.
Conversely, if the pitch played at the 12th fret is higher than the harmonic, move the
bridge saddle backward (Fig. 5 H) to lengthen the string length. The method of adjusting
depends on the type of bridge your guitar has, so carry out adjustments referring to the
adjustment manual for your bridge.
Caution
The string may break if the saddle is moved a substantial distance, so be sure
to loosen the string before you adjust the saddle if a major adjustment is required.
