• JC CLEAN gives you a clean sound, LEAD can be switched between a variety of tones, and SOLO lets you store and call up the settings for your own sounds.
• CUBE-20GX only The LEAD channel provides six pedal effects: ACOUSTIC SIM, OVERDRIVE, DISTORTION, METAL, METAL STACK, and the original EXTREME.
• CUBE-40GX/80GX only The LEAD channel provides a total of ten COSM amp types including acoustic, clean, crunch, high gain, and the original "Dyna Amp."
• Footswitch (sold separately) can be connected, allowing you to switch channels with your foot.
• CUBE-40GX/80GX only By using a GA foot controller (GA-FC; sold separately) you can switch channels as well as turn EFX, DELAY, and REVERB on/off.
• MASTER VOLUME allows you to adjust the overall volume.

COSM ( Composite Object Sound Modeling) is Roland's innovative and powerful sound modeling technology. COSM analyzes the many factors that make up the original sound, such as the electrical and physical characteristics of the original, and then produces a digital model that can reproduce the same sound.

"EFX" provides five types of effects, plus independent reverb and delay

• Onboard EFX section includes 5 types of digital effect, CHORUS, FLANGER, PHASER, TREMOLO, and HEAVY OCTAVE.
• DELAY and REVERB are independent; choose either WARM or CLEAR for the DELAY effect, and either SPRING or PLATE for the REVERB effect.

A tuner function is included

• An easy-to-operate tuner is built in, allowing you to tune while leaving your guitar connected.
• Chr omatic tuning is supported.
• CUBE-40GX/80GX only Flat tuning and 7-string guitars are also supported.

CUBE-20GX only
You can select from the following six amp types:

Type	Explanation
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 unprecedented 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.

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.

PRESENCE
[PRESENCE] knob CUBE-80GX only
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.

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.

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.

* For information on how to set the delay time, refer to "DELAY".

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.

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.

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.
