Roland Cube-15X Owner's Manual

To connect your guitar to the Roland Cube-15X amplifier, use a standard 1/4-inch guitar cable. Plug one end into the output jack of your guitar and the other end into the 'Input' jack on the amplifier's control panel.
For a clean sound, set the 'GAIN' to a low level, 'BASS' and 'MIDDLE' to around 5, and 'TREBLE' to your preference. Keep the 'VOLUME' at a comfortable level. Ensure the 'CHANNEL SELECT' button is set to 'CLEAN'.
First, check if the power cord is properly connected and the power switch is on. Ensure your guitar and cables are functioning correctly. Make sure the 'VOLUME' is turned up and try a different outlet or power source.
Press the 'TUNER' button on the amplifier. Play a single open string on your guitar, and the LED indicators will display whether the note is sharp, flat, or in tune. Adjust the tuning pegs on your guitar accordingly.
Periodically check the cables and connections for any wear or damage. Dust the exterior with a soft cloth and avoid exposure to moisture. Inspect the power cord for frays or damage.
Select the 'LEAD' channel using the 'CHANNEL SELECT' button. Adjust the 'GAIN' knob to your desired level of distortion, and fine-tune with the 'BASS', 'MIDDLE', and 'TREBLE' controls.
Ensure the amplifier is placed in a well-ventilated area and not in direct sunlight. Avoid covering the vents. If overheating persists, turn off the amp and let it cool down before using it again.
Yes, plug your headphones into the 'RECORDING OUT/PHONES' jack. This will mute the speaker and allow you to practice silently.
The Roland Cube-15X does not have a factory reset function, as it is an analog amplifier with limited digital settings. Simply adjust the knobs manually to return to default settings.
Store the amplifier in a cool, dry place. Cover it with a dust cover to prevent dust accumulation. Ensure it is unplugged and cords are neatly coiled.
