How do I turn on the CUBE-10GX amplifier?

The COSM amplifier section provides three amp types: CLEAN (modeled Roland JC-120), CRUNCH (modeled Marshall JMP1987), and LEAD (modeled MESA/Boogie Rectifier). Press the AMP TYPE switch to cycle through them; the indicator color shows the current selection (green=Clean, orange=Crunch, red=Lead).

How do I use the built-in effects?

Turn the EFFECT knob to select one of three effects: Chorus, Delay, or Reverb. The knob also adjusts effect depth. For spring reverb, set the knob to the SPRING position.

Can I use headphones with the CUBE-10GX?

How do I use the CUBE-10GX app to customize amp types?

Long-press the AMP TYPE switch until the indicator blinks to enter CUBE-10GX app mode. Connect your smartphone to the amplifier's INPUT jack using an adaptor plug, then use the dedicated app to replace the current amp type with your own selection. Press the AMP TYPE switch again to exit app mode.

How do I restore factory settings for amp types?

Hold down the AMP TYPE switch while turning on the power. The AMP TYPE indicator will blink, and the amp types will be restored to their original factory presets.

The AUX IN jack allows you to connect an external audio player (e.g., smartphone, MP3 player) using a stereo mini-plug cable. This lets you play along with backing tracks or music. Adjust the volume from the connected device.

How do I clean and maintain the CUBE-10GX?

Use a soft, dry cloth to clean the amplifier. Avoid solvents or abrasive cleaners. Keep the unit away from moisture and extreme temperatures. Ensure proper ventilation to prevent overheating.

* The speaker and REC OUT/PHONES output is mono.
* Determine the volume level by adjusting the volume control of the connected device.
* When connection cables with resistors are used, the volume level of equipment connected to the inputs (AUX IN) may be low. If this happens, use connection cables that do not contain resistors.

* The product names mentioned in this document are registered trademarks or trademarks of their respective owners. In this manual, these names are used because it is the most practical way of describing the sounds that are simulated using COSM technology.
