SWITCHING FUNCTION

The output level of theinstrument as well as thequality of the signal can beaffected by the pickup height.Pickup height should beadjusted until the volume ofneck and bridge pickups arealmost equal with bothvolumes wide open. The volume may drop drastically if the pickupheight is too low. As the pickups are magnetic, fret buzzing anddistortion may occur if the pickup is too close to the strings. Use a smallscrewdriver to make adjustments to raise or lower the pickup.*Instruments that have adjustable pole pieces can be adjusted to balance the output of each string.

PICKUPSIbanez steel string models are equipped with adjustable truss rods. Thepurpose of a truss rod is to adjust the neck to counteract string tension.There are many reasons for truss rod adjustments. One of the mostfrequent reasons is changing string gauges or tuning pitch which canaffect string tension. String tension changes may affect the string heightand cause fret buzz or notes that don’t ring true. To adjust the truss rod,locate the truss rod nut and adjust it by inserting the correct wrench intothe nut and tightening (clockwise) or loosening (counter clockwise) therod. Truss rod tension can be measured by installing a capo at the firstfret the holding the strings down at the fret position where the neck joinsthe body. Insert a thickness gauge between the string and the fret at the8th fret. There shouldbetween 0.3 mm to 0.5mmclearance. That clearance isreferred to as “neck relief.”Too much neck relief cancause the neck to havehigher action in the middle ofthe neck causing poorintonation and uncomfortableplayability. No neck relief cancause fret buzz.*Appropriate care must be taken whenadjusting the neck and we recommend onlyqualified technicians perform this procedure.

Regular cleaning of yourguitar is one the mostimportant ways you canmaintain the finish andlengthen string life. Afterplaying, wipe down yourinstrument to remove anyperspiration from theinstrument. Perspiration can actually contain acids that can be corrosiveto the strings and metal parts of the guitar. Gloss finish guitars should bepolished with polish formulated specifically for musical instruments, anda soft, treated guitar cloth or a cotton rag. Abrasive rags such aspolyester can scratch the finish. Oil finished guitars should be wipedclean immediately after playing with a dry cotton rag only. If your guitarhas become discolored due to extended use or heavy perspiration,factory appearance, see a qualified guitar repair person about methodsto restore the oil finish to its original factory appearance.

Maintenance ➣➣

Our congratulations and deepest thanks onmaking Ibanez your choice of instrument. Ibanezstandards are second to none. All Ibanezinstruments are set up to our strict quality controlstandards before shipping. The purpose of thismanual is to explain how to maintain yourinstrument’s finish and to keep your guitar playingas well as it did when it left our factory.

If strings become dirty, discolored, or produce adull sound or buzz, replace the strings with newones. For best results we recommend replacingone string at a time, this will help to avoidremoving the string tension from the neck. Whenreplacing strings with different gauge strings, itmay be necessary to adjust the truss rod tension.(We recommend only qualified techniciansperform this.) Instruments that have tremolosystems installed may need to be adjusted afterstring replacement as changes in string tensioncan cause the tremolo to raise or lower. Ibanezguitars and basses are factory equipped with thefollowing string gauges. Please follow theinstructions below for your particular model.The strings should be tightly wound on to thetuning machines from top to bottom with 2 to 3string wraps around the post. In the case ofunwound guitar strings, the ends of the stringsshould be prepared as shown in the diagram toprevent unintentional slippage from the posts. Inthe case of tuning machines, where the stringends are inserted into the posts, the string can becut to length in advance using a pair of stringcutters.If the tuning machines are sealed gear units, theyare self-lubricating types. The set screws for the tuning knob areadjustment screws that can be tightened with a small Phillips headscrewdriver to increase the tension.*The use of coarse strings may lead to buzzing and sound distortion. Using strings that have twists or kinks maycause buzzing or decreased sustain. Make sure that the new strings are smooth and free from any defectsbefore installing.

Intonation adjustment isthe operation ofadjusting the location ofthe string at the saddleto compensate fordifferent string gaugesor different tunings.Follow the instructionsof the particular bridge intonation below. Intonation is properly set whenthe 12th fret note and the 12th fret harmonic are exactly the same note .This is the center point of the scale and the most accurate way of settinga standard scale length. With the harmonic note as the standard, if thefretted note is flat move the bridge saddle forward toward the headstock(a) to decrease the string length. If the fretted note is sharp, move it backaway from the headstock (b) to increase the string length intonationadjustments. *Please note that strings can be broken when the saddle is moved, so always loosen the strings beforemaking adjustments.

INTONATION

Ibanez guitar and bass string action is set at thefactory. However there are many reasons that aninstrument’s string height can change. Instrumentscan be affected by changes in temperature andmoisture. High string action can make the guitardifficult to play. If the string action is too low, fretbuzz or unclear notes can occur. To remedy this,follow the instructions for the particular type ofbridge installed. In the case of string action, makesure the guitar is in tune and the truss rod is adjusted properly. Ibanezaction is set at the 14th fret. The action may also need to be readjustedafter the neck has been adjusted or strings have been changed to adifferent gauge. Follow the instructions in the relevant bridge manual tomake adjustments.* If strings other than those described above are used, gradually increase the action clearance from the treble sidethrough to the bass side.

The Ibanez DOWNSHIFTER allows the pitch of a string to be dropped to apreset desired position with a simple lever operation. To achieve precisetuning for both the up and down positions, you will need to preset bothlever settings before operating the Downshifter.

PLEASE NOTE: The Downshifter device was designed to provide thehighest level of pitch accuracy. However, it should be understood thatthe Downshifter is a mechanical device. Pitch variations and tuningreadjustments, especially after frequent use, are to be expected.

(C)

tuning screw clockwise to reduce the pitch,or counter clockwise to raise the pitch. Thisadjustment can be done by hand or with astandard screwdriver or a coin until thedesired down pitch is acquired. (The presetfactory pitch is set one whole step down toD.) When the lever is raised to the upposition, the thumbscrew can be turnedfreely but will have no effect on the raised lever pitch. However, it willaffect the settings of down lever pitch.

TUNINGFirst check that the Downshifter lever arm israised to the up position then tune the stringnormally using the standard tuning machineson the headstock. (Note: the Downshifter tuning screw has noeffect on the pitch in the up position.) Next,lower the lever on the Downshifter to the down position and the pitch ofthe string will drop down.

ILTADJUSTING THE TREMOLO SPRINGThe tremolo springs adjust thetremolo angle by tightening orloosening the tremolo tension. Toadjust tremolo angle, locate theadjustment screws in the reartremolo cavity. The tremolo systemwhen in tune should sit parallel tothe surface of the guitar as follows.If the tremolo system is not sittingparallel to the surface of the guitar, remove the tremolo cavity coverplate and tighten the Tremolo tension adjustment screws if the tremolois forward dumped. Loosen the screws if the tremolo is up-pulled.

Retune the strings to the proper pitchand check the angle. Choose the numberand placement of the tremolo springsaccording to the string gauge and thetremolo angle.

REPLACING THE STRINGSIn the case of EDGE III tremolo, replace thestrings one by one. Removing all the old stringsat once will release the tension on the tremoloand change the tremolo angle “up-pull.” Loosenthe Pressure pad screw (D) on the locking nutand loosen the string to be replaced. Loosen theString stopper screw (G) and remove the stringfrom the saddle. Cut off the ball end of newstring as shown on the illustration and insert the cut side of new stringbetween the saddle and the String holder block.Tighten the Stringstopper screw (G) and tune the string. After checking the intonation,tighten the Pressure pad screw (D) on the locking nut.

ADJUSTING THE STRING HEIGHTThe height adjustment of the tremolo can beraised or lowered by adjusting the pivot studs(B) that the tremolo mounts on. These arelocated at either side of the front of the bridge.Clockwise lowers the tremolo and counterclockwise raises the tremolo.

Tighten the Saddle lock screw (F)and tune the string. After rechecking theintonation, tighten the Pressure pad screw (D).

EDGE IIIADJUSTING THE TREMOLO SPRINGThe tremolo springs adjust the tremoloangle by tightening or loosening thetremolo tension. To adjust tremoloangle, locate the adjustment screws inthe rear tremolo cavity. The tremolosystem when in tune should sit parallelto 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 tensionadjustment screws if the tremolo is forward dumped. Loosen the screws

if the tremolo is up-pulled.Retune thestrings to the proper pitch and check theangle. Choose the number and placementof the tremolo springs according to thestring gauge and the tremolo angle.

ADJUSTING THE ACTIONTo 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 tremolounit. (This cannot be adjusted for eachindividual string.)

FINE TUNINGEven after locking the locking nut, you can usethe fine tuners to make fine adjustments to thetuning of each string. You should adjust all ofthe fine tuners (C) to the center of adjustablerange before you lock the locking nut.

ARM ACTIONThe tremolo arm action can be adjusted byusing a 3.0mm Allen wrench on the screw (B)of the tremolo screw.

ARM ROTATION TORQUEThe rotation torque of the arm can be adjustedby raising the tremolo and inserting a 1.5mmAllen wrench in the screw (A) on the tremoloblock, turning this screw clockwise willtighten the arm torque and turning the screwcounter clockwise will loosen the arm torque.

ADJUSTING THE INTONATION &THE STRING HEIGHT (FAT 6)The intonation can be adjusted byadjusting the saddle forward orbackward using a philips(+) headadjustment screw at the rear of thebridge. String height is controlled byraising or lowering the small allenscrews using a wrench on either sideof the saddle.

TREMOLO ARM INSTALLATIONThe tremolo arm can be inserted andremoved very easily. Insert the arminto the armhole on the tremolo baseplate. Pull up on the arm to remove it.

ARM ROTATION TORQUEThe rotation torque of the arm can beadjusted by raising the tremolo andinserting a 1.5mm Allen wrench inthe screw (A) on the tremolo block,Turning this screw clockwise willtighten the arm torque and turningthe screw counter clockwise willloosen the arm torque.

ADJUSTING THE STRING HEIGHT (FAT20/FAT10/SAT10)The height adjustment of the tremolo can be raised or lowered byadjusting the pivot studs (C) that the tremolo mounts on. These arelocated at either side of the front of the bridge. Clockwise lowers thetremolo and counter clockwise raises the tremolo.

ADJUSTING THE STRING HEIGHT (SAT PRO)To adjust the action of eachstring, use a 1.5 mm Allenwrench to turn the screw on thesaddle (C). The overall heightcan be adjusted on either sideof the SAT PRO tremolo unit. Toadjust the height, use a 3 mmAllen wrench to turn the stud (D)located on either side of theunit. Use caution whenadjusting the height of the entire tremolo unit; adjust both sides to thesame height to ensure optimum tremolo operation.

FAT/SAT (expect FAT6)ADJUSTING THE TREMOLO SPRINGA standard tremolo can be adjustedso that the pitch can be raised whenthe tremolo arm is pulled up toloosen the tremolo springs locatedunder the tremolo cavity on the backof the guitar. One disadvantage ofthis procedure is that it can causethe pitch to go sharp if string breaks.To remedy this, adjust the tremoloplate so it sits flush on the body bytightening the tremolo springs.Choose the number andplacement of the tremolosprings according to the stringgauge and the tremoloadjustment . FLOATING PARALLEL

REPLACING THE STRINGSTo replace strings, thread the newstrings through the string holeslocated on the back of the guitar. Thestrings are then threaded through thetremolo block and up and over thesaddle.

EDGE PRO II TREMOLO

REPLACING THE STRINGSThe EDGE-PRO II tremolo will accommodateeither strings from which the ball end hasbeen cut, or conventional strings fromwhich the ball end has not been cut.To remove a string, use a 3 mm Allenwrench to loosen the pressure pad screw ofthe locking nut (Fig.1), remove the stringfrom the tuning machine, and use a 3 mmAllen wrench to loosen the string stopperscrew of the saddle (Fig.2). Turning thiscounter-clockwise will automatically retractthe holder block, so loosen the string stopperscrew all the way until the holder blockstops retracting. Remove the old string,insert approximately 3 cm of the new stringwith ball end into the saddle, and whilemaking sure that the string is positioned inthe center of the saddle, tighten the stringstopper screw (Fig.2). Turning this clockwisewill automatically advance the holder block,so after making sure that the string is firmlyfastened, wind the string around the tuningmachine post, tune it, and then tighten thepressure 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 toprevent the winding from loosening. Insert approximately 1~3 cm of thetip into the saddle, and install the string in the same way as aconventional string from which the ball end has not been cut off.Since the attachment angle of the tremolo will change significantly if allstrings 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 thelength of string to be inserted. The appropriate length will be inserted ifyou insert the string until the tip contacts this guide.If a string breaks at the saddle, it may fall into the tremolo cavity whenyou loosen the string stopper screw. Remove the broken string either bydetaching the tremolo spring cavity cover plate from the back of theguitar, or from the opening in the cover plate. If the broken springremains 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 threeturns after the holder block has stopped retracting.

ADJUSTING THE INTONATIONBefore you adjust the intonation, use a 3 mm Allen wrench to loosen thepressure pad screws (G) of the locking nut so that the strings arereleased. Use a 2 mm Allen wrench to loosen the saddle lock screws (F)of each saddle, and move the saddle. Firmly tighten the saddle lockscrews, tune the guitar, and then check the intonation. Repeat theseadjustments until the intonation is correct, and then tighten the pressurepad screws of the locking nut.You may install each saddle lock screw in either the forward or rearposition, depending on the position of the saddle.The unit is designed so that the fine tuning screw will not operate if theposition 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 beforemaking adjustments.

FINE TUNINGEven after locking the lockingnut, you can use the fine tuners(Fig.10 A) to make fineadjustments to the tuning ofeach string.You should adjust all of the finetuners to the center of theiradjustable range before you lockthe locking nut.

ZR (ZERO RESISTANCE) TREMOLO

TREMOLO SPRINGSThe EDGE-PRO II tremolo is designed tofunction optimally when it is installedapproximately parallel with the surfaceof the guitar body (Fig.4). The angle atwhich the tremolo is attached can beadjusted by changing the length of thetremolo springs inside the tremolo springcavity in the back of the guitar body.Working through the adjustment holes inthe tremolo spring cavity cover plate, usea Philips (+) screwdriver to turn thetremolo tension adjustment screws toadjust the length of the tremolo springs.If the tremolo is tilted forward toward theneck of the guitar (Fig.5), turn the screwsclockwise to tighten the springs.Conversely, if the tremolo is tiltedbackward away from the neck (Fig.6),turn the screws counter-clockwise toloosen the springs. Tune the guitaraccurately, re-check the angle of thetremolo, and repeat the adjustment untilthe tremolo angle is correct. The EDGE-PRO II tremolo is designed to functionoptimally when three springs aretensioned equally with a 0.009" gaugeset 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 theway 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 thetremolo springs to the block. Before you change the number of springs orthe way in which they are installed, use a Philips (+) screwdriver toremove the block lock (Fig.7).

NOTE: If you want to install four or five tremolo springs, insert the springs into the block nutattachment screw holes. (In this case, it will not be possible to attach the block nut.)
