Type Explanation	COSM
ACOUSTIC SIM	This original amp model gives you a dynamic acoustic guitar sound using a standard electric guitar.
OVERDRIVE	Natural distortion sound similar to that obtained by turning an amp's volume up completely.
DISTORTION Harder distortion than OVERDRIVE.
METAL	Even harder and heavier than DISTORTION, which can get long sustained notes.
METAL STACK Very fat sound of a Heavy Metal full amp stack.
EXTREME	High-gain sound delivering thick lows and intense distortion while still preserving the sound's clear definition.

CUBE-40GX/80GX only

You can select from the following ten amp types:

Type Explanation
ACOUSTIC SIM	This is an original amp type that includes an acoustic simulator.Using this type together with a single-coil pickup in the front position produces optimal sound quality.If you're using humbucker pickups, turn down the equalizer's BASS and MIDDLE controls slightly.
BLACK PANEL	This is modeled on the classic Fender Twin Reverb amplifier.It's used in a wide range of musical styles, from country to blues, jazz, and rock.It features rich lows and a bright high end.
DLX COMBO	This is modeled on the Fender Deluxe Reverb amplifier.This amp finds use in a full range of genres, including surf music, blues, country, jazz, soul, and hard rock.It features clear, clean tones and sparkling overdrive at high volumes.
BRIT COMBO	This is modeled on the Vox AC-30TB.This is the rock amplifier that created the Liverpool sound of the 1960s.It can produce a broad range of sounds, from clean to overdrive.
TWEED	This is modeled on the vintage Fender Tweed Bassman 4 x 10" Combo.It produces a clear mid to upper range with a fat low end, and its unique crunch tones with persistent distortion have earned it a loyal following among blues and rock guitarists.
CLASSIC STACK	This is modeled on the features of a Marshall JMP 1987.Used extensively in hard rock in the 1970s, this is truly the perfect amp for the "top rock" guitar sound.
METAL STACK	This is modeled on the Peavey EVH 5150.This is a high-gain amp, so you can get heavy distortion and sustain even at low volumes.
R-FIER STACK	This super high-gain amp is modeled on the Mesa/Boogie Rectifier.This is a super high-gain amp. It's capable of producing slash metal, grunge, and a wide range of other lead sounds.
EXTREME	This original high-gain amp delivers thick lows and intense distortion while still preserving the sound's clear definition.
DYNA AMP	This is an original amp type that lets you obtain unprec-edented tonal changes according to your picking dynamics.Soft picking produces a transparent clean amp sound, whereas hard picking yields a deeply distorted high-gain amp sound.Once the sound is distorted, the tone then changes according to the force used in picking, greatly expanding your range of expression.Setting the [GAIN] knob at the optimal position provides maximum effectiveness. Start with the [GAIN] knob centered. Then adjust the [GAIN] knob so that soft picking yields a clean tone and hard picking produces heavy distortion.

[GAIN] knob

This adjusts the distortion level for the LEAD channel.

[VOLUME] knob

This adjusts the volume level for the LEAD channel.

7 EQUALIZER

[BASS] knob

This adjusts the sound level of the low-frequency range.

[MIDDLE] knob

This adjusts the sound level of the middle-frequency range.

[TREBLE] knob

This adjusts the sound level of the high-frequency range.

CUBE-40GX/80GX only

* When the LEAD channel Type switch is set to BLACK PANEL, DLX COMBO, or TWEED, setting [BASS] knob, [MIDDLE] knob and [TREBLE] knob all to 0 (zero) stops all sound.

8 PRESENCE

This gives the midrange and high end a more lustrous contour. This is effective when you want to make the sound more airy and open.

9 EFX

[EFX] knob

Turn this knob to select the effect. Turn the knob to adjust the amount of effect applied.

The indicator lights up when this is on, and goes out when it's off.

* Graduations for each effect on a panel are for reference. Be sure to check the sound as you adjust the effects.

Knob Position Explanation
CHORUS	This adds a slightly detuned sound to the original sound, giving the sound greater breadth and fullness.
FLANGER	This creates a flanging effect that creates a sort of spinning sensation with the sound.
PHASER	This adds a phase-shifted signal to the original sound, giving the sound a swirling sensation.
TREMOLO	This effect produces cyclical changes in the volume level.
HEAVY OCTAVE	This adds sound lowered by an octave to the original sound. Since you can play chords even when using this effect, you can use it to fatten the sound of your chordal playing as well.

CUBE-40GX/80GX only

You can also switch this on and off using a GA foot controller (GA-FC; sold separately).

10 DELAY

[DELAY] knob

You can switch between use of two types of delay by changing the position of the knob. The position of the knob within this range adjusts the volume of the delay sound.

GA-FC jack CUBE-40GX/80GX only

You can connect the separately sold Roland GA-FC to switch channels and turn effects on/off.

Connecting the GA foot controller (GA-FC; sold separately)

Connect a stereo cable to the FOOT SW GA-FC jack of the CUBE-40GX/CUBE-80GX.

* Always use a stereo cable.
* Use cables that do not contain resistors.

Using the GA-FC

You can use the GA-FC to switch between JC CLEAN, LEAD, and SOLO (MEMORY). You can also switch EFX, DELAY, and REVERB on/off.

Switch Explanation
JC CLEAN Selects the JC CLEAN channel.
LEAD Selects the LEAD channel.
SOLO Selects the SOLO channel.
EFX Turns EFX on/off.
DELAY Turns DELAY on/off.
REVERB	Turns REVERB on/off.

* Once you've turned off EFX, DELAY, or REVERB from the GA-FC, you must first turn the corresponding knob to the OFF position in order for the [EFX], [DELAY], or [REVERB] knobs of the amp itself to be re-enabled.

Using the expression pedals

By connecting expression pedals (Roland EV-5, BOSS FV-500L, BOSS FV-500H; sold separately), you can change the input volume and master volume by pedal.

Pure electrical circuit lines without any symbols

Expression pedals

Jack	Explanation
INPUT VOL	Adjusts the input volume.* The input volume that is controlled by the expression pedal connected to this jack cannot be adjusted from the panel.
MASTER VOL	Adjusts the master volume. This lets you use volume changes as a performance technique, or to mute your instrument.* The master volume that is controlled by the expression pedal connected to this jack is different than that of the [MASTER] knob on the panel.

Setting MINIMUM VOLUME of an expression pedal

With the [MINIMUM VOLUME] knob of an expression pedal, you can set the value for when the pedal is lifted up all the way (lowest value).

* Use only the specified expression pedal (Roland EV-5, BOSS FV-500L, BOSS FV-500H; sold separately). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.

Memory/FC priority mode (EFX, DELAY, REVERB on/off)

You can specify how EFX, DELAY, and REVERB will operate when you switch the channel.

* The changed setting will be remembered even if you turn off the power.

Memory priority mode (factory setting)

When you select SOLO, the stored on/off settings will take priority.

To make this setting

Turn on the power while holding down the CUBE's [JC CLEAN] button.

* Hold down the button until all LEDs blink.

FC priority mode

The on/off statuses of the GA-FC will always take priority when you switch channels.

To make this setting

Turn on the power while holding down the CUBE's [LEAD] button.

* Hold down the button until all LEDs blink.

Turning the Power On/Off

* Once everything is properly connected (p. 4–p. 9), be sure to follow the procedure below to turn on their power. If you turn on equipment in the wrong order, you risk causing malfunction or equipment failure.

1. Make sure that the CUBE's [MASTER] knob and the volume of the devices connected to the CUBE are set to 0.

* Set the [MASTER] knob to 0 before you connect anything to the CUBE's INPUT jack or i-CUBE LINK/AUX IN jack.

1. Turn on the power of the devices connected to the CUBE's INPUT jack and i-CUBE LINK/AUX IN jack.

2. Turn on the CUBE.

* Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.

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

1. Turn on the power of the devices connected to the LINE OUT jack (CUBE-80GX only) and RECORDING OUT/PHONES jack.

2. Adjust the volume levels for the devices.

Before switching off the power, lower the volume on each of the devices in your system and then TURN OFF the devices in the reverse order to which they were switched on.

* If you need to turn off the power completely, first turn off the unit, then unplug the power cord from the power outlet. Refer to "To completely turn off power to the unit, pull out the plug from the outlet" (p. 2).

CUBE-20GX CUBE-40GX/CUBE-80GX

* The illustration shows the CUBE-80GX

Manual Tuning

1. Press the [TUNER] button.

The unit enters the Tuner mode and the [TUNER] button lights up.

* No sound will be output from the speaker or from any of the jacks.
* The sound input to the i-CUBE LINK/AUX IN jack is output.

2. Use the TYPE switch to select the string that you want to tune.

Knob Position String (note name)
7B	Open seventh string of a seven-string guitar (B)	CUBE-40GX/CUBE-80GX only
6Eb	Open sixth string (semitone down) (E b)
6E Open sixth string (E)
5A Open fifth string (A)
4D	Open fourth string (D)
3G	Open third string (G)
2B	Open second string (B)
1E Open first string (E)
Ab	Open fifth string (semitone down) (A b)	CUBE-40GX/CUBE-80GX only
Abb	Open fifth string (whole tone down) (G)

* The reference pitch is A = 440 Hz. This cannot be changed.

3. Play a single note on the open string that you want to tune.

Tune the string until the green indicator lights.

graph LR
    A["Flat"] --> B["Pitch is correct"]
    B --> C["Sharp"]
    D["TUNER"] --> E["Lights red"]
    F["TUNER"] --> G["Lights green"]
    H["TUNER"] --> I["Lights red"]

* The red indicator blinks if the pitch is substantially out of tune.

4. When you have finished tuning, press the [TUNER] button once again.

Chromatic Tuning

If you hold down the [TUNER] button for one second or longer, the [TUNER] button blinks and the unit becomes usable as a "chromatic tuner," which automatically determines the name of the note closest to the one played.

As with manual tuning, chromatic tuning allows you to play a single note on the string that you want to tune. Tune the string until the green indicator lights.

Using i-CUBE LINK

"i-CUBE LINK" allows you to use the included mini cable (4-pole) to connect your iPad/iPhone so that audio can be played back from the iPad/iPhone while the sound of your guitar playing on the CUBE is sent to the iPad/iPhone.

This function lets you use an iPad/iPhone app to record and play back the sound of your guitar.

* If you only want to hear the sound that's being input from the iPad/iPhone, turn down the [VOLUME] knob of each channel.

For details on i-CUBE LINK and on iPhone/iPad apps that can use i-CUBE LINK, refer to Roland website.

Restoring the Factory Settings

Here's how the settings stored in the CUBE can be returned to their factory-set condition (factory reset).

1. While holding down the [LEAD] button and [SOLO] (MEMORY) button, turn the power on.

• All indicators will blink, and the settings stored in SOLO will return to their factory-set state.
• The CUBE will return to memory priority mode (p. 9) (CUBE-40GX/80GX only).

Sample Settings (CUBE-20GX)

Extreme

This is an extreme sound with intense distortion.

This is a high-gain sound that packs a lot of punch in the low end, while delivering a great deal of edge in the upper range.

You can obtain variations in the sound by moving the [MIDDLE] knob.

If you turn on HEAVY OCTAVE, you can achieve an even greater sense of distortion in the low end.

Space Clean

This is a transparent sound using spatial effects.

To the JC CLEAN sound that models the JC-120, this adds chorus, long delay, and reverb.

Using this setting with a guitar equipped with single coil pickups makes great sounding arpeggios and chord strumming.

Depending on the phrase being played, it can be effective to set the delay sound's delay time slightly slower than the phrase's tempo.

Power Grunge

This produces a raging distortion sound that is very trebly and roughly textured.

Setting the [GAIN] knob to prevent excessive distortion of the guitar sound results in a straight guitar sound with brilliant harmonics and powerful chord sounds.

You can also add the FLANGER to produce a sound with a powerful swirling effect, much like the sound from a jet.

Additionally, using the guitar's front pickup and raising the [GAIN] and [MIDDLE] knobs results in a fat lead sound with long sustain.

Alternative Metal

The perfect sound for heavy, sharp riffs.

Select the high-gain METAL STACK, then use the equalizer to boost the low end even more.

Used with a humbucking pickup in the rear position, it results in an extreme distortion effect.

Plus, you can add a long delay to use this as a lead sound with great sustain.

Sample Settings (CUBE-40GX/CUBE-80GX)

* For information on how to set the delay time, refer to "DELAY" (p. 6).

Extreme

CUBE-40GXCUBE-80GX

This is an extreme sound with intense distortion.

This is a high-gain sound that packs a lot of punch in the low end, while delivering a great deal of edge in the upper range.

You can obtain variations in the sound by moving the [MIDDLE] knob.

If you turn on HEAVY OCTAVE, you can achieve an even greater sense of distortion in the low end.

Space Clean

This is a transparent sound that uses spatial effects.

Use the JC CLEAN amp, which is modeled on the Roland JC-120, and add chorus, long delay, and reverb.

Using this setting with a guitar that has single-coil pickups makes for arpeggios and chord strumming with beautiful resonance. If you're using a guitar with humbucker pickups on CUBE-80GX, turn the [BRIGHT] button to ON to achieve a bright, open sound.

Setting the delay time to a value that makes the delay sound heard slightly ahead of the tempo of the phrase played produces a thicker sound.

Surf Line

CUBE-40GXCUBE-80GX

This sound is perfect for the surf music popular in the 1960s.

Using this setting with a guitar that has single-coil pickups makes for an edgy sound.

Applying deep spring reverb and using muting picking and chromatic runs (muted picking with glissandos) produces the classic surf sound.

Rockabilly Slap

This is the slapback-echo sound used in rockabilly and country.

The BLACK PANEL amp produces a clean sound that is bright and sweet, with a powerful midrange and high end supported by a thick bass. By making the low and high ends more prominent while keeping them balanced, and also suppressing the midrange if the situation calls for it, you can bring out the dazzling resonance of the guitar even more beautifully.

The sound of a guitar that has single-coil pickups with heavy tremolo and reverb applied is also distinctive.

Loud Metal

This sound produces heavy low-end reverberations when lower strings are played while muted, and airy sustain when chords are played.

Playing with a humbucking rear pickup produces even more extreme distortion. What's more, you can make the sound even heavier by using drop tuning or other such settings.

When you want to make the distortion edgier on CUBE-80GX, boost the [PRESENCE] setting. Also, when you're using this as the lead sound, raising the midrange and applying a long delay produces a fat sound with sustain.

Dynamic Style

DYNA AMP is an original amp that uses relative picking intensity to create changes in distortion depth.

First, adjust the [GAIN] knob so that a clean tone is obtained with soft picking and heavy distortion is obtained when you pick hard. Now mixing arpeggios played with a gentle touch along with firmly picked chords and solos results in a guitar sound with huge dynamics. Now, to create a broader, more open sound on CUBE-80GX, cut the midrange and raise the low end and presence. Using this in combination with the EFX as well as delay and reverb creates a sound with an even greater feeling of scale.
