Roland Cube 10 GX Mini kombo

Roland CUBE-10GX — A Compact COSM Combo Amp for Practice and Recording

Roland CUBE-10GX is a 10-watt mini combo guitar amp built for bedroom practice, lesson rooms, and quick studio tracking. It pairs a custom 8-inch speaker with COSM amp-modeling engine and three switchable channels (Clean, Crunch, Lead). This combo is the right choice for guitarists who want a small, durable amp with serious tonal range.

What Sets the CUBE-10GX Apart

Most practice amps at this size lock you into a fixed set of tones, but this model lets you swap the three onboard COSM channels for seven additional amp types via the free CUBE KIT app on iOS or Android. The Rec Out/Phones jack mutes the onboard speaker and sends a direct signal with COSM speaker modeling for silent practice and recording.

Power and Speaker — Loud Enough for the Room, Quiet Enough for Night Practice

Output and cabinet design determine how an amp feels at playing volume, and this combo is tuned for personal-use levels. The custom 8-inch driver and rigid cabinet deliver full, balanced tone at low volumes, while heavy-duty corner protectors keep the enclosure safe during transport.

• Maximum Power Output: 10 W — comfortable volume for solo practice without overwhelming a small room.
• Speaker: 20 cm (8 inches), custom-designed — full-range response tuned for the cabinet.
• At 4.7 kg, the cabinet is light enough to carry one-handed to lessons or rehearsals.

COSM Amp Modeling and Tone Shaping — Three Channels, Seven Swappable Models

COSM (Composite Object Sound Modeling) is Roland's approach to recreating classic amp voicings digitally. This combo ships with Clean, Crunch, and Lead presets, and the CUBE KIT app lets you replace those three slots with vintage combos, high-gain stacks, and bass or acoustic-electric profiles. A three-band EQ fine-tunes the chosen model.

• You can choose between Clean, Crunch, Lead presets to cover sparkling cleans, classic rock breakup, and modern lead tones.
• App-Expandable Models: 7 additional COSM amps via CUBE KIT — including JC Clean, Black Panel, Brit Combo, Tweed, Orng Stack, Classic Stack, Metal Stack, R-Fier, Acoustic, and Bass.
• A three-band EQ with Bass, Middle, and Treble shapes the selected COSM model.

Onboard Effects and Connections — Headphone Practice, Aux Jamming, Direct Recording

Built-in effects and rear-panel jacks make this combo more than a practice-only amp. Chorus, delay, and reverb (with plate and spring variations) are dialed in via a single EFFECT knob, while the Rec Out/Phones jack doubles as a direct recording output. An Aux In lets you play along with tracks from a phone.

• Onboard Effects: Chorus, Delay, Reverb (plate and spring) — three studio-quality effects from a single knob.
• Headphone Output: Yes (Rec Out/Phones jack) — mutes the speaker for silent practice and routes COSM-modeled tone to headphones.
• Aux In: Stereo miniature phone type — plug in a phone to jam with backing tracks.
• Power comes from the included AC adaptor (DC 5.7 V); no battery operation.

Who the Instrument Is Built For

This combo is the right choice for bedroom players, students, and gigging guitarists who need a compact backup amp that covers multiple genres. Beginners benefit from the simple control layout — gain, volume, three-band EQ, and a single effect knob. Experienced players get real value from the CUBE KIT app for sketching ideas or recording direct into an audio interface.

The CUBE Series — Portable Amps Since 1978

The series has been a fixture for portable players since 1978, evolving from a single battery-powered combo into a full family of practice and stage amps. This combo continues that lineage with COSM modeling, smartphone app expandability, and heavy-duty cabinet construction.
