Roland Cube-30 Owner's Manual

To connect your guitar to the Roland Cube-30, use a standard 1/4-inch instrument cable. Plug one end into your guitar's output jack and the other end into the INPUT jack on the amplifier. Make sure the amp is turned off while making connections to avoid any noise or damage.
For a clean sound, set the EQ knobs to the 12 o’clock position as a starting point. Then adjust the bass, middle, and treble to your preference, considering your guitar's natural tone and the room acoustics.
The Cube-30 comes with built-in effects like reverb, delay, and chorus. Use the EFX knob to select and adjust the intensity of the desired effect. Rotate the knob to the desired effect labeled on the panel, and fine-tune using the knob’s position.
Check if the power cable is securely connected to both the amplifier and a working power outlet. Ensure the power switch is in the 'ON' position. If the amp still does not power on, inspect for a blown fuse by consulting the user manual for replacement instructions.
Keep the amplifier in a dust-free environment and clean it regularly with a dry cloth. Avoid exposure to extreme temperatures and moisture. Check cables and connections periodically and store the amp in a safe place when not in use.
Yes, the Cube-30 has a PHONES/RECORD OUT jack. Simply plug your headphones into this jack to practice silently. Make sure to adjust the volume accordingly to prevent hearing damage.
Check for any nearby electronic devices that might cause interference. Ensure all cables are properly connected and in good condition. If the problem persists, try using a different power outlet or consult a technician.
Use the AMP TYPE knob to switch between different amp models. Rotate the knob to select various amp simulations such as JC Clean, Black Panel, or Metal Stack, each providing a different tonal characteristic.
Yes, the Cube-30 can be used for recording. Connect the PHONES/RECORD OUT jack to your recording interface or device using the appropriate cable. This output provides a direct signal suitable for recording.
To prevent feedback, position yourself away from the amplifier and avoid facing the speaker directly. Lower the gain or volume levels, and consider using a noise gate or other signal processing equipment if feedback persists.
