Frequently Asked Questions - miKro GSRM20 IBANEZ

How to clean my Ibanez miKro GSRM20?

After each use, clean it with a polishing cloth. For glossy finishes, use a special musical instrument product. Never use benzene or thinner.

How to adjust the intonation of my bass?

Intonation is correct when the note at the 12th fret and the harmonic at the same fret are identical. If the fretted note is flat, move the saddle toward the headstock (shorten the string length). If sharp, move toward the bridge. Loosen the strings before moving the saddle.

How to adjust string height?

Use an Allen wrench to turn the height screw on the bridge saddle. Turn clockwise to raise the saddle (increase height), counterclockwise to lower. Recommended height at the 12th fret is 2.5 mm for the bass strings and 2.0 mm for the treble strings.

How to adjust the neck (truss rod)?

Locate the adjustment nut (usually under a cover near the headstock). Use the appropriate Allen wrench: turn clockwise to tighten (reduce the relief), counterclockwise to loosen. The gap between the string and the 8th fret should be 0.3 to 0.5 mm. Have this done by a technician if you are inexperienced.

What batteries to use and how to replace them?

Use a good quality 9V alkaline battery. The compartment is under the control plate cover. Respect polarity (+ and -). Remove the battery if you do not use the bass for a long time. Do not mix old and new batteries.

When should I change the strings?

Replace the strings when they are dirty, discolored, produce a dull sound or buzzing. Change strings one at a time to avoid sudden changes in neck tension.

What to do if strings are buzzing?

First check tuning. If buzzing persists, string height may be too low, or the neck needs adjustment. Also check that strings are not worn or of poor quality.

How to store my bass to avoid damage?

Store it in a case or gig bag, away from extreme temperature and humidity variations. Do not lean it against a chair or table. On stage, use a stable stand.

Can I repair my bass myself?

It is advisable not to attempt repairs or disassembly if you are inexperienced. For delicate adjustments (neck, intonation), contact a qualified Ibanez or authorized technician.

How to adjust the pickup balance (blend)?

The blend control mixes the two pickups. Turn the knob clockwise to increase the neck pickup and decrease the bridge, counterclockwise for the opposite. The center position gives an equal level.

INTRODUCTION

Our congratulations and deepest thanks on making Ibanez your choice of instrument. Ibanez standards are second to none. All Ibanez instruments are set up to our strict quality control standards before shipping. This manual explains how to maintain your instrument's finish and how to keep your bass at the same great level of playability and performance it had when it left our facilities.

INSTRUCTIONS AND SAFETY PRECAUTIONS

1) After each playing session, wipe the entire bass down, including strings, with a good polishing cloth. This will remove corrosive skin oils and acids, and protect the plating, finish, and strings. Gloss finish basses should be polished with polish formulated specifically for musical instruments. Do not wipe the instrument with volatile substances, such as benzene or thinner. Please ventilate the room fully when using an aerosol (spray) cleaner.
2) Keep your bass in an area that is not excessively dry or wet and, since temperature affects relative humidity, an area which is not excessively hot or cold. This will prevent damage and possible electric shock.
3) Unless you are trained in musical instrument repair, it is advisable not to attempt to dismantle or repair your instruments. Please seek professional advice through your authorized Ibanez bass dealer.
4) Because strings can break or snap and cause possible injury to your face (and especially eyes), it is recommended to keep a reasonable distance between the strings and your face when playing or when changing and adjusting the strings.
5) Because of atmospheric changes in humidity and temperature, it is normal for the fingerboard to shrink, which may leave the fret ends exposed. Please be aware that these fret ends can be sharp enough to cause injury.
6) It is advisable to change strings regularly. Old and tarnished strings will sound dull and lifeless and are more subject to breakage. Tuning strings too high will also break them. If you are not sure of a tuning note, it is better to start over and loosen the string and then tune up to the correct pitch rather than risk over-tuning.
7) Do not play a bass with rusty strings; this can cause injury to your fingers.
8) The cut or clipped end of a guitar or bass string is very sharp; please do not touch the end of a cut string directly with your fingers.

9) If you use a strap, make sure it is completely and securely attached to the strap buttons before playing your bass.
10) "Don't Try This At Home." Doing tricks and gymnastics with your bass such as throwing or twirling it (in imitation of stage tricks of some pro-bassists), can be dangerous to you and others as well as cause irreparable damage to your instrument, which is not covered under warranty.
11) To avoid injury, please be aware that some pickguards have sharp edges.
12) Always store your bass in a case or gig bag and avoid leaning it against chairs or tables as there is possibility of the bass tipping over which can result in severe damage to your instrument. On stage, always use a secure and stable instrument stand.
13) Before lifting your bass case or gig bag, make sure that the catches or zippers are secure-a bass can easily fall from an open case, causing damage.
14)The + (positive) and - (negative) contacts on the battery and contacts on the compartment or snap must match. If the battery is installed "backwards" (i.e. with reversed polarity), the electronics will not work and the battery will eventually overheat with the possibility of damage to the bass and even fire.
15) Always dispose of batteries properly. Never put batteries into a fire as they can explode and cause serious injury.

STRINGS

If strings become dirty, discolored, or produce a dull sound or buzz, replace the strings with new ones. For best results we recommend replacing one string at a time, this will help to avoid removing all the string tension from the neck. When replacing strings with different gauge strings, it may be necessary to adjust the truss rod tension. (We recommend only qualified technicians perform truss rod adjustments.) Ibanez basses are factory equipped with the following string gauges. Please follow the instructions below for your particular model.

The strings should be tightly wound on to the tuning machines from top to bottom with 2 to 3 string wraps around the post. On tuning machines where the string ends are inserted into the posts, the string can be cut to length in advance using a pair of string cutters.

If the tuning machines are sealed gear units, they are self-lubricating types. The set screws for the tuning knob are adjustment screws that can be tightened with a small Phillips (+) head screwdriver to increase the tension.

The use of coarse strings may lead to buzzing and sound distortion. Using strings that have twists or kinks may cause buzzing or decreased sustain. Make sure that the strings are smooth and free from any defects before installing.

To install the string on to the bridge, thread the new string through the string holes located on the back of the tailpiece and bring them up and over the saddle. For bridges that require special installation instructions, please see the appendix at the end of this manual.

NECK

Ibanez basses are equipped with adjustable truss rods. The purpose of a truss rod is to adjust the neck to counteract string tension. There are many reasons for truss rod adjustments. One of the most frequent reasons is changing string gauges or tuning pitch, which can affect string tension. String tension

changes may affect the string height and cause fret buzz or incorrect notes. To adjust the truss rod, locate the truss rod nut and adjust it by inserting the correct wrench into the nut and tightening (clockwise) or loosening (counter clockwise) the rod. Truss rod tension can be measured by installing a capo at the first fret, holding the string down at the fret position where the neck joins the body. Insert a thickness gauge between the string and the fret at the 8th fret. There should be between 0.3 mm to 0.5 mm clearance. That clearance is referred to as "neck relief." Too much neck relief can cause the neck to have higher action in the middle of the neck causing poor intonation and uncomfortable playability. No neck relief can cause fret buzz.

*Appropriate care must be taken when adjusting the neck and we recommend only qualified technicians perform this procedure.

ACTION

Ibanez bass string action is set at the factory. However, there are many reasons that an instrument's string height can change. Instruments can be affected by changes in temperature and moisture. High string action can make basses difficult to play. If the string action is too low, fret buzz or unclear notes can occur. To remedy this, follow the instructions for the particular type of bridge installed. In the case of string action, make sure the bass is in tune

and the truss rod is adjusted properly. Ibanez action is set to 2.0mm for the treble side and 2.5mm for the bass side at the 12th fret. The action may also need to be readjusted after the neck is adjusted or strings are changed to a different gauge. Follow the instructions in the relevant bridge manual to make adjustments.

To raise or lower the string action, insert the correct Allen wrench into the screw at the saddle. To raise the saddle, turn the wrench clockwise and to lower the saddle, turn the wrench counter clockwise.

INTONATION

Intonation adjustment is the operation of adjusting the location of the string at the saddle to compensate for different tuning. Follow the instructions of the particular bridge intonation below. Intonation is properly set when the 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 setting a standard scale length. With the harmonic note as the standard, if the fretted 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 back away from the headstock (b) to increase the string length intonation adjustments.

*Please note that strings can be broken when the saddle is moved. So always loosen the strings before making any adjustments.

Intonation adjustment can be made by adjusting the intonation screws at the rear of the bridge clockwise to move the saddle back and counter clockwise to move the saddle forward.

ACOUSTIC BRIDGE POSITION

On a full hollow bass, the entire bridge is moved forward or back to adjust intonation. Based on the 12th fret harmonic, if the 12th fretted note is flat, move the bridge toward the headstock. If the note is sharp, move the bridge toward the tail piece (away from the headstock).

You need to loosen the strings to make adjustments, but this may cause the bridge to move too much. If this occurs, adjustment will be easier if you aim for a scale length of 770mm / 30.3'' between the nut (0 fret) and saddle of the first string. Once the adjustment is made, change strings one at a time to minimize saddle movement.

PICKUP

The output level of the instrument as well as the quality of the signal can be affected by the pickup height. Pickup height should be adjusted until the volume of neck and bridge pickups are almost equal with both volumes wide

open. The volume may drop drastically if the pickup height is too low. As the pickups are magnetic, fret buzzing and distortion may occur if the pickup is too close to the strings. Use a small screwdriver 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.

BASS CONTROLS

Pickup Balancer (on all two-pickup models.) The pickup balance control pot allows the user to blend between the front and rear pickups using a single pot. The center position of the pot has a de-tent which will set both pickups to equal output. Turning the knob clockwise increases the neck pickup while decreasing the output of the bridge pickup. Turning the knob to the neck pickup and increases the output of the bridge

*For the specific controls on your bass, please see the appendix at the end of this manual.

BATTERIES

On basses with active electronics (some basses do not require batteries) the battery is stored inside of a battery box or a control cavity. To avoid damage caused by leaking batteries, remove old batteries as soon as possible and do not store your bass for long periods of time with the batteries installed. Do not mix batteries - either older with new, or alkaline with non-alkaline, etc. - in basses that require two batteries.

Inserting a plug into the output jack activates the power supply. Unplug the instrument cable when bass is not in use in order to reduce drain on the battery.
