Do not attempt to repair the unit, or replace parts within it (except when this manual provides specific instructions directing you to do so). Refer all servicing to your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page.

Never install the unit in any of the following locations.

WARNING

In households with small children, an adult should provide supervision until the child is capable of following all the rules essential for the safe operation of the unit.

Protect the unit from strong impact. (Do not drop it!)

•Subject to temperature extremes (e.g., direct sunlight in an enclosed vehicle, near a heating duct, on top of heat-generating equipment); or are

•Damp (e.g., baths, washrooms, on wet floors); or are

•Exposed to steam or smoke; or are

•Subject to salt exposure; or are

•Humid; or are

•Exposed to rain; or are

•Dusty or sandy; or are

•Subject to high levels of vibration and shakiness.

Make sure you always have the unit placed so it is level and sure to remain stable. Never place it on stands that could wobble, or on inclined surfaces.

Be sure to use only the AC adaptor supplied with the unit. Also, make sure the line voltage at the installation matches the input voltage specified on the AC adaptor’s body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.

Use only the attached power-supply cord. Also, the supplied power cord must not be used with any other device.

Do not excessively twist or bend the power cord, nor place heavy objects on it. Doing so can damage the cord, producing severed elements and short circuits. Damaged cords are fire and shock hazards!

This unit, either alone or in combination with an amplifier and headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level, or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should immediately stop using the unit, and consult an audiologist.

Do not place containers containing liquid on this product. Never allow foreign objects (e.g., flammable objects, coins, wires) or liquids (e.g., water or juice) to enter this product. Doing so may cause short circuits, faulty operation, or other malfunctions.

Immediately turn the power off, remove the AC adaptor from the outlet, and request servicing by your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page when:

•The AC adaptor, the power-supply cord, or the plug has been damaged; or

•If smoke or unusual odor occurs

•Objects have fallen into, or liquid has been spilled onto the unit; or

•The unit has been exposed to rain (or otherwise has become wet); or

•The unit does not appear to operate normally or exhibits a marked change in performance.

Do not force the unit’s power-supply cord to share an outlet with an unreasonable number of other devices. Be especially careful when using extension cords–the total power used by all devices you have connected to the extension cord’s outlet must never exceed the power rating (watts/ amperes) for the extension cord. Excessive loads can cause the insulation on the cord to heat up and eventually melt through.

Before using the unit in a foreign country, consult with your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page.

CAUTION

The unit and the AC adaptor should be located so their location or position does not interfere with their proper ventilation.

Always grasp only the plug on the AC adaptor cord when plugging into, or unplugging from, an outlet or this unit.

At regular intervals, you should unplug the AC adaptor and clean it by using a dry cloth to wipe all dust and other accumulations away from its prongs. Also, disconnect the power plug from the power outlet whenever the unit is to remain unused for an extended period of time. Any accumulation of dust between the power plug and the power outlet can result in poor insulation and lead to fire.

Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed so they are out of the reach of children.

Never climb on top of, nor place heavy objects on the unit.

Never handle the AC adaptor or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit.

IMPORTANT NOTES

Power Supply

•Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter (such as a refrigerator,

washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet.

•The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.

•Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices.

Placement

•Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference.

•This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.

•Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.

•Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. Excessive heat can deform or discolor the unit.

•When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated.

•Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface.

You can place a piece of felt or cloth under the rubber feet to prevent this from happening. If you do so, please make sure that the unit will not slip or move accidentally.

•Do not put anything that contains water on this unit. Also, avoid the use of insecticides, perfumes, alcohol, nail polish, spray cans, etc., near the unit. Swiftly wipe away any liquid that spills on the unit using a dry, soft cloth.

Maintenance

•For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent.

Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth.

•Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Repairs and Data

•Please be aware that all data contained in the unit’s memory may be lost when the unit is sent for repairs. Important data should always be backed up on USB memories or written down on paper (when possible). During repairs, due care is taken to avoid the loss of data. However, in certain cases (such as when circuitry related to memory itself is out of order), we regret that it may not be possible to restore the data, and Roland assumes no liability concerning such loss of data.

Using External Memories

•Carefully insert the USB memories all the way in—until it is firmly in place.

•Never touch the terminals of the USB memories. Also, avoid getting the terminals dirty.

•USB memories are constructed using precision components; handle the cards carefully, paying particular note to the following.

•To prevent damage to the cards from static electricity, be sure to discharge any static electricity from your own body before handling the cards.

•Do not touch or allow metal to come into contact with the contact portion of the cards.

•Do not bend, drop, or subject cards to strong shock or vibration.

•Do not keep cards in direct sunlight, in closed vehicles, or other such locations.

•Do not allow cards to become wet.

•Do not disassemble or modify the cards.

•To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you.

•When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.

•The explanations in this manual include illustrations that depict what should typically be shown by the display. Note, however, that your unit may incorporate a newer, enhanced version of the system (e.g., includes newer sounds), so what you actually see in the display may not always match what appears in the manual.

Additional Precautions

•Please be aware that the contents of memory can be irretrievably lost as a result of a malfunction, or the improper operation of the unit. To protect yourself against the risk of loosing important data,

we recommend that you periodically save a backup copy of important data you have stored in the unit’s memory on USB memories.

•Unfortunately, it may be impossible to restore the contents of data that was stored in the unit’s memory or on USB memories once it has been lost. Roland Corporation assumes no liability concerning such loss of data.

•Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using

its jacks and connectors. Rough handling can lead to malfunctions.

•Never strike or apply strong pressure to the display.

•When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable’s internal elements.

•When you operate the expression pedal, please be careful not to get your fingers pinched between the movable part and the panel.

In households with small children, an adult should provide supervision until the child is capable of following all the rules essential for the safe operation of the unit.

Main Features

Sound: Sophisticated fusion of a PCM synthesizer and COSM modeling sound generator

Sounds produced by a high-quality PCM synthesizer and a realistic COSM modeling sound generator can be freely combined to take advantage of each method’s unique characteristics.

You can intuitively create new sound combinations with a high degree of freedom. For example, you could create a new lead guitar sound that’s based on a standard distorted guitar combined with a synth lead or organ. Alternatively, you might layer a flute or a synth bell sound with an acoustic guitar to create fantastic new tones.

COSM amps and various effects units are provided independently, allowing you to create an incredible variety ranging, from raw guitar amp sounds to tricky noise sounds.

Expressiveness: Newly developed guitar pitch detection technology

The independent pickup signal from each of the six strings is analyzed at high speed by a newly developed algorithm, ensuring quick and accurate response from the sound generator.

In addition, your picking position as well as the differences between notes played with a pick or with your fingers are also detected and transmitted to the sound generator, giving the GR-55 a range of performance expression that’s much broader and more natural than any previous guitar synthesizer.

Easy use: Use SOUND STYLE to select a sound, and use EZ EDIT to edit it

The three SOUND STYLE buttons “LEAD,”“RHYTHM,” and “OTHER” provide performance-ready sounds in a wide range of musical styles. A large-screen LCD ensures excellent visibility at your feet.

Press the [EZ EDIT] button to make easy graphical adjustments to the sound; this is a great convenience especially when playing live.

What is the COSM?

Technology that simulates existing physical structures, materials, and the like using different, virtual means is called “modeling technology.” COSM (Composite Object Sound Modeling) is a technical innovation from Roland that combines a number of such sound-modeling technologies to create new and unique sounds.

Settings

This chapter explains how to make the necessary settings when using the GR-55 for the first time.

First, get your guitar/bass ready

•In order to use the GR-55, you’ll need a guitar or bass equipped with a divided pickup (GK pickup), which outputs a separate signal for each string.

You can use GK pickups such as the Roland GK-3 or GK-3B.

•For details on how to install a GK pickup, refer to the owner’s manual that came with your GK pickup.

MEMO

•Be aware that string buzz due to a warped neck or worn frets, or faulty octave adjustment, can cause problems such as wrong notes being produced.

•This unit does not support 7-string guitars/basses or other non-standard guitars/basses.

Check the Web for details about installing GK pickups

•On the Roland website, the “GK-3/3B Installation Tips” page provides an explanation and photos on how to attach a GK pickup. Be sure to take a look!

http://www.roland.com/GK/

Preparations for Using the GR-55

Connections

Guitar equipped with a GK-3/ GK-2A, bass equipped with a GK-3B/GK-2B, or a commercially available GK-ready guitar or bass

The GUITAR OUT jack outputs the sound of the normal pickups and the sound of the modeling tone (p. 22).

For details, refer to “GUITAR OUT Jack Settings (GUITAR OUT)” (p. 54).

Amp or PA (line)	Headphones

If you’re using monaural output, connect only to the L/MONO jack.

Place the AC adaptor so the side with the indicator (see illustration) faces upwards and the side with textual information faces downwards.

The indicator will light when you plug the AC adaptor into an AC outlet.

To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook,as shown in the illustration.

NOTE!

•To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.

•Switch on the power to all of your equipment before you raise the volume of the amp.

Turning the Power On/Off

Turning the power on

Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

*Always make sure to have the volume level turned down before switching on power.. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction..

*This unit is equipped with a protection circuit.. A brief interval (a few seconds) after power up is required before the unit will operate normally..

1.Press the GR-55’s [POWER] switch to turn the power on..

2.Turn on the power of your amp..

Turning the power off

1.Check the following before you turn the power off..

Preparations for Using the GR-55

Adjusting Your Guitar Pickup

1.Use the cursor [] [] buttons to move the cursor to “PU TYPE,” and use the dial to select the type of pickup that’s installed on your guitar..

		Value	Description
		GK-3	Choose this if you’re using a GK-3.
		GK-2A	Choose this if you’re using a GK-2A.
		PIEZO	This setting is appropriate if you’re using a piezo pickup that
			has a flat response.
		PIEZO F	This setting is appropriate for a Fishman piezo pickup.
		PIEZO G	This setting is appropriate for a Graph Tech piezo pickup.
		PIEZO L	This setting is appropriate for an L.R. Baggs piezo pickup.
		PIEZO R	This setting is appropriate for an RMC piezo pickup.

A piezo pickup is a type of pickup that is mounted on the bridge of the guitar, and uses a piezoelectric element to detect the vibrations of the strings.

If you’re using a guitar equipped with a GK pickup that’s not of the piezo type, choose “GK-2A.”

*If you’re not sure which piezo type setting is appropriate, try selecting different choices while you play your guitar, and choose the piezo type that produces the most natural sound.. In this case, the difference will be easier to notice if you turn off the PCM 1 and 2 tone switches (p.. 25)..

*If you’ve chosen PIEZO, PIEZO F, PIEZO G, PIEZO L, or PIEZO R as the PU Type setting, you’ll be able to make further adjustments to the tone quality of the high range and low range (p.. 75)..

2.Use the cursor [] [] buttons to move the cursor to “SCALE,” and use the dial to specify your guitar’s scale length (the distance between the bridge and nut)..

Choose the closest value in the range of 500–660 mm.

Choose “ST” (648 mm) for a standard Stratocaster type, or choose “LP” (628 mm) for a Les Paul type. For details on the other parameters, refer to “GK SETTING” (p. 74).

3. Use the PAGE [ ] [ ] buttons to select the DIS tab..

4. Use the cursor [ ] [ ] buttons to select each string, and for each string, specify the distance from the center of the pickup to the bridge saddle..

*If PU TYPE is set to one of the piezo-type pickups, this setting is not necessary..

5.	Use the PAGE [	] [	] buttons to select the SEN tab..
6.	Use the cursor [	] [	] buttons to move the cursor to 6TH
	STRING SENS..

Play the 6th string as strongly as you ever expect to play it in actual performance, and use the dial to adjust the sensitivity as high as possible without allowing the meter to reach the full-scale position.

*If the level meter reaches the full-scale position, the level is excessive.. Lower the sensitivity..

*Depending on the guitar you’re using, the level meter might reach full-scale even if the sensitivity is at minimum.. If this is the case, adjust the distance between the divided pickup and the string so it’s somewhat greater than the recommendation..

7.In the same way, adjust the sensitivity for the 5th through 1st strings as well..

8.Check the volume balance of the six strings..

Play each of the strings 6–1 at normal strength; if a string sounds unusually loud, lower the sensitivity of that string to minimize any discrepancy in volume between the strings.

9.Press the [EXIT] button a number of times to return to the top screen..

These settings are required when you’ve newly installed a divided pickup on your guitar, or when you’ve adjusted the height of the divided pickup. These settings will be retained even while the power is switched off. Once you’ve made them correctly, there’s no need to make them again each time you perform. For details on the other parameters, refer to “GK SETTING” (p. 74).

Quick Guide

This chapter explains basic operation.

Before you play, you should set your GK pickup’s select switch to “MIX”!

If a different setting is selected, the sound might not be output correctly.

Selecting and Playing Sounds

Now that you’ve finished with preparations, here’s how to operate the GR-55 while you play.

Adjusting the Output Level

1.Adjust the GR-55’s output level by turning the [OUTPUT LEVEL] knob..

Turning the knob toward the right will increase the volume;

turning the knob all the way toward the left will set the volume to zero. Normally, you can place the knob near the center position.

Step on the expression pedal. Raise the GK pickup’s volume knob.

Selecting a Sound (Patch)

What is a Patch?

A “patch” is a unit of sound on the GR-55; in addition to settings determining the type of sound, the patch also includes effect settings.

You are free to modify (edit) the settings of a patch and store it in the GR-55 as a “user patch.” (Patches that are already built into the GR-55 are called “preset patches.”)

For more about patches, refer to “How the GR-55 Works” (p. 22).

What is a Bank?

A “bank” is a collection of three patches.

What is a Sound Style?

The GR-55 lets you select preset patches from three “sound styles.” First select the style of sound that you want to play, and then select a patch from within that style.

	Sound style	Summary
	LEAD	Sound styles suitable for soloing, such as lead guitar
		sounds and wind instruments.
	RHYTHM	Sound styles suitable for backing, such when comping
		chords or playing arpeggios.
	OTHER	Sound styles that include effective, characteristic
		synthesized sounds.

Step 1

Choose the sound style of the sound you want to play.

Selecting and Playing Sounds

Selecting a User Patch

New patches that you create are saved in the GR-55 as “user patches” (p. 18).

Press the [USER] button to select user patches in Step 1 of “Selecting a Sound (Patch).”

The rest of the procedure is the same as when selecting a preset patch.

Playing Your Guitar

You can apply effects to the sound by pressing the following pedals while you play.

[CTL] pedal

When you press this pedal while playing, an effect specified for each patch will be applied; for example, raising the synthesizer sound by an octave, or extending the decay of the synthesizer note you’re playing.

You are also free to change this effect to your taste (p. 61).

Expression pedal

When you operate this pedal while playing, the effect assigned to each patch will be applied.

Normally, the volume will change, but depending on the patch, a variety of other effects may be assigned.

If you depress this pedal completely, placing your weight on the toe, the EXP PEDAL SW indicator will light, and the expression pedal will switch to a different function. Normally, it will control an effect such as wah pedal, but this too may be assigned to a different effect depending on the patch.

You can change each of these effects according to your taste (p. 61).

*When operating the expression pedal, be careful so as not to get your toes pinched between the moving portion and the main part of the GR-55.. If there are young children in your household, don’t let them use or play with the GR-55 without adult supervision..

Editing the Tones (TONE)

Using the Nuance parameters

The Nuance parameters detect when you play your guitar/bass with a soft touch, and apply a corresponding change to the sound of the PCM tone.

For example, if CUTOFF NUANCE SENS is set to a positive “+” value, the cutoff frequency of the PCM tone will be lowered when you play a muted or a finger-picked note, producing a softer tone quality.

As another example, you might use PCM TONE 1 to create the sound that will be heard when you pluck the string with a pick, and PCM TONE 2 to create the sound that will be heard when you pluck the string with your finger. Then set the Nuance parameters as follows, allowing you to switch between PCM TONE 1 and 2 by alternating your performance technique.

•PCM TONE 1 settings

TONE CATEGORY/NUMBER: the tone sounded for a note played with a pick LEVEL NUANCE SENS: +50

•PCM TONE 2 settings

TONE CATEGORY/NUMBER: the tone sounded for a note played with your finger LEVEL NUANCE SENS: -50

To enable the Nuance parameters, turn NUANCE SW “ON” and adjust each NUANCE SENS parameter as desired.

If you want to adjust the nuance so it’s appropriate for the guitar or bass you’re using, set the SYSTEM - GK SETTING parameters NUANCE DYNAMICS and NUANCE TRIM (p. 75).
