Power Supply: Use of Batteries
- 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.
- The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.
- When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way, you can prevent malfunction and/or damage to speakers or other devices.
- 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. 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 the 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.
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.
Additional Precautions

4. Select a rhythm variation by pressing the VARIATION button.
Each genre contains three types of rhythm variations. Pressing the VARIATION button cycles you through the available variations; the VARIATION indicator will be unlit, will light green, or will light red to indicate the change in variation.
5. Adjust the variation to the tempo that you want to play to.
Press the TAP TEMPO button two or more times at the desired tempo to get the RHYTHM GUIDE to play at that tempo.

Tube Crunch

The perfect sound for heavy, sharp riffs.
Select the high-gain R-FIER amp, then use the equalizer to boost the low and high ends.
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.
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 beautiful 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.
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, to produce a sound with great punch.
Turning down the GAIN knob is also a perfect way to get a sharp crunch sound.
This is a sound that complements blues music.
Turn down the BASS knob a little and turn up the GAIN knob to obtain a smooth crunch sound.
This is due to sound boosted by the equalizer being distorted by the GAIN knob. You can also obtain a sharp crunch sound by further boosting the high end or lowering the midrange.
