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.
• 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.
• Although the LEDs are switched off when the POWER switch is switched off, this does not mean that the unit has been completely disconnected from the source of power. If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. For this reason, the outlet into which you choose to connect the power cord's plug should be one that is within easy reach and readily accessible.

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. Also, do not allow lighting devices that normally are used while their light source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for extended periods of time. 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.
• Do not allow rubber, vinyl, or similar materials to remain on this unit for long periods of time. Such objects can discolor or otherwise harmfully affect the finish.
• Do not paste stickers, decals, or the like to this instrument. Peeling such matter off the instrument may damage the exterior finish.
• 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 (e.g., flower vases) 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.

Turn this knob to CHORUS, FLANGER, PHASER, TREMOLO, or HEAVY OCTAVE to select the corresponding effect, or to SOLO. Turn the knob to adjust the amount of effect applied.

The ON indicator lights up when EFX is turned on, and goes out when EFX is turned off. You can also turn EFX on and off using optional foot switches

Graduations for CHORUS, FLANGER, PHASER, TREMOLO, SOLO, HEAVY OCTAVE on a panel are for reference. Be sure to check the sound as you adjust the effects.

Type	Description
CHORUS	In this effect, a slightly detuned sound is added 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 effect adds a variable phaseshifted signal to the direct sound, giving the sound a swirling character.
TREMOLO	Tremolo is an effect that creates a cyclic change in volume.
SOLO	This applies a boost effect to the original sound. By using a foot switch to turn SOLO on/off individually for the JC CLEAN and LEAD channels, you can vary the volume and distortion of your sound.
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.

DELAY/REVERB

12. [DELAY/REVERB] Knob

Turn this knob to DELAY or REVERB to switch to that effect. Turn the knob to adjust the amount of effect applied. Set the knob to the SPRING position to enjoy the sound of a spring reverb unit.

When using manual tuning, you can press the [SELECT] switch to sound a tuning reference tone at the pitch selected by the Type switch.

1. Press the [TUNER] switch.

CUBE-20XL enters the Tuner mode and the [TUNER] switch lights up.

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

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

3. Use the JC CLEAN channel's [VOLUME] knob to adjust the volume.

4. Press the [SELECT] switch.

The reference tone will sound at the pitch of the string selected by the Type switch.

5. Play a single note on the open string that you want to tune. Play an open string or a harmonic, and tune your guitar to match the reference tone.

6. When you have finished tuning, press the [TUNER] switch once again.

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 spacial effects.

Select the JC CLEAN amp, modeled on the Roland JC-120, then add chorus and long delay.

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.

Adding a short delay produces a doubling sound like that from two performers playing the same phrases simultaneously.
