Power Supply

Additional Precautions
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.
Use a reasonable amount of care when using the units buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.
When connecting / disconnecting all cables, grasp the connector itselfnever pull on the cable. This way you will avoid causing shorts, or damage to the cables internal elements.
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.
A small amount of heat will radiate from the unit during normal operation.
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 cords plug should be one that is within easy reach and readily accessible.
To avoid disturbing your neighbors, try to keep the units volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you (especially when it is late at night).
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.

Maintenance

Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions. Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable. Wrap the power cord around the cord hook when transporting or storing the unit.

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.

Panel descriptions

Control Panel

fig.01-01

1. INPUT Jack

Connect your guitar here.

BRIT COMBO

This is modeled on the Vox AC-30TB, the rock amplifier that created the Liverpool sound of the 60s. It can produce a broad range of sounds, from clean to overdrive, with increased distortion and greater power in the low-midrange when the amplifiers gain is boosted.

2. SELECT Switch

Switches between the CLEAN and LEAD channels. You can confirm which channel is selected by checking the indicators color (JC CLEAN: left; LEAD: right). Channels can be switched using optional BOSS FS-5U or FS-6 footswitches.
This is modeled on the vintage Tweed Fender Bassman 4x10 combo. The amplifiers four 10-inch speakers produce a clear upper-midrange with a fat low end, and its unique crunch tones make it a favorite of blues-rock guitarists.

3. TUNER Switch

The switch lights in red when the tuner function is on; the switch is unlit when the tuner is off. For more detailed information, refer to p. 8.

CLASSIC STACK

This is modeled on the sound and response of a Marshall JMP1987. The legendary JMP1987 is renowned for its smooth tone and presence-perfect for classic and hard rock.

JC CLEAN Channel

This is a model of Rolands famous JC-120 Jazz Chorus guitar amplifier. The ultra-clean, ultra-flat sound offers a smooth feel.

METAL STACK

This is modeled on the Peavey EVH-5150. This is the high gain amp, so even at low volumes, you can still get heavy distortion and sustain.

4. VOLUME Knob

Adjusts the JC CLEAN channel volume.

LEAD Channel

5. Type Switch
You can select from the following eight types. When the tuner function is on, you can use this to select the name of the string to be tuned (p. 8).

R-FIER STACK

This is modeled on the MESA/Boogie Rectifier. This super high gain amp is capable of producing slash metal, grunge, and a wide range of other lead sounds.

DYNA AMP

This is an original amp sound that lets the player create previously unobtainable tonal changes according to the picking strength. Soft picking produces a transparent clean amp sound, while hard picking results in 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.

ACOUSTIC

By combining acoustic guitar simulation with COSM amplifier modeling technology, this original amplifier model gives you a dynamic acoustic guitar sound using a standard electric guitar.

BLACK PANEL

This is modeled on the classic Fender Twin Reverb amplifier, used in a wide variety of musical styles, from country to blues, jazz and rock. Exhibiting rich lows and a bright high end.
Use of the RECORDING OUT/PHONES jack allows even better reproduction of the COSM-modeled sound.

CUBE-30X_e.book 10

Sample Settings

Alternative Metal

The perfect sound for heavy, sharp riffs. Select the high-gain R-FIER amp, 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.

SELECT : LEAD

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

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 sounds delay time slightly slower than the phrases tempo.

SELECT: JC CLEAN

Classic Rock
This is a 70s-style rock sound. Turning up the gain produces a powerful rock sound in all riffs and solos. A powerful low end is a characteristic of the sound emitted by the surfaces of the cabinet, so you can turn up the equalizer knobs, especially the BASS knob, and increase to produce a sound with great punch. Turning down the GAIN knob is also a perfect way to get a sharp crunch sound.

Dynamic Style

DYNA AMP is an original amp that uses relative picking strength to create changes in distortion depth. First, adjust the GAIN knob so that a clean tone is obtained with soft picking and deep 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, cut the midrange and raise the low end.
Using this in combination with the EFX and delay and reverb creates a sound with an even greater feeling of scale.
