Roland Cube 20GX F.A.Q.

How do I connect my Roland Cube 20GX to an external speaker?

To connect the Roland Cube 20GX to an external speaker, use the "Rec Out/Phones" jack with a suitable adapter. This will mute the internal speaker and allow you to use external amplification.

What should I do if the amplifier does not power on?

Check the power cable for any damage and ensure it is properly plugged into a working outlet. Verify that the power switch is in the "on" position. If the issue persists, consult a professional technician.

How can I achieve a clean sound on the Cube 20GX?

To get a clean sound, set the "Clean" channel on the mode selector and adjust the "Volume" knob to your desired level. Keep the "Gain" knob low to avoid distortion.

Why is there no sound coming from my amp despite being powered on?

Ensure the volume is turned up, and check that no cables are loose or damaged. Also, verify that the "Rec Out/Phones" jack is not occupied, as this mutes the internal speaker.

What is the correct way to maintain the Cube 20GX amplifier?

Keep the amplifier in a dry environment, dust it regularly, and use a cover when not in use. Avoid exposing it to extreme temperatures and never block the ventilation ports.

Can I use the Cube 20GX as a practice amp with headphones?

Yes, the Cube 20GX has a "Rec Out/Phones" jack that allows you to connect headphones for silent practice. This automatically mutes the internal speaker.

How do I perform a factory reset on the Roland Cube 20GX?

To reset the Cube 20GX to factory settings, turn off the amp and hold down the "Lead" and "Power" buttons simultaneously while turning the amp back on.

What effects are built into the Cube 20GX amplifier?

The Cube 20GX includes effects such as chorus, delay, reverb, and more, which can be selected and adjusted using the "EFX" and "Delay/Reverb" knobs.

How do I troubleshoot feedback issues with the Cube 20GX?

Reduce feedback by lowering the gain, volume, or treble settings. Ensure your position relative to the amp avoids direct pickup by the microphone or guitar.

Is it possible to switch channels using a footswitch on the Cube 20GX?

Yes, you can use a footswitch (such as the Roland GA-FC) to switch between channels and control other features hands-free. Connect it to the "Foot SW" jack.
