Boss Dual Cube LX Modelling Combo

Boss Dual Cube LX — Stereo Desktop Guitar Amplifier with Pro Tones and Effects

The Boss Dual Cube LX is a compact stereo desktop guitar amplifier built for players who want authentic BOSS amp character without dragging a full combo to the gig. Two custom 4-inch speakers and a 10 W stereo power amp deliver full, punchy guitar tones from a chassis small enough to sit on a desk. The Dual Cube LX is the right choice for guitarists who need a portable practice, recording, and livestreaming hub that goes anywhere AC power or eight AA batteries can reach.

What Sets the Boss Dual Cube LX Apart in the Desktop Amp Category

Where most desktop amps stop at a handful of tones, the Dual Cube LX ships with eight newly developed amp types plus a dedicated mic preamp type, each with two variations and three user memories for a total of 27 storable patches. A dedicated Stereo In amp type adds advanced spatial processing so modelers and stereo pedalboards sound like they are running through a much larger cabinet, with an alternate JC-120-inspired voicing selectable from the editor app.

Amp Power and Speaker Configuration — Desktop Volume with Real Stereo Width

Stereo imaging is the headline feature of this amp, and the hardware is built around it. Two custom 4-inch speakers and a 10 W stereo power amp split into 5 W + 5 W give the Dual Cube LX a wider, more immersive soundstage than a typical mono practice combo at this size. Players who stream, record, or use stereo pedals will hear the difference immediately through headphones, line out, or the speakers themselves.

• Rated Power Output: 10 W (5 W + 5 W) stereo — enough headroom for small-room practice and quiet coffee-shop sets.
• Speakers: Two custom-designed 4-inch (10 cm) drivers — tuned for full-range response that supports bass-heavy patches without bottoming out.
• Amp Types: 8 guitar amp types + 1 mic preamp type — Acoustic Sim, JC Clean, US Combo, Brit Combo, Hi-Gain Stack, Metal Stack, Extreme, Mic, and Stereo In.

Onboard Effects, EQ, and Looper — Tone Shaping Without External Pedals

The panel controls put serious sound design within reach. A three-band EQ (Bass, Middle, Treble) sits alongside dedicated Gain and Volume knobs, while the Effects knob covers Chorus, Flanger, Phaser, Tremolo, and Heavy Octave, and the Delay/Reverb knob covers Delay, Reverb, and Spring. The onboard looper records up to 90 seconds in mono or 45 seconds in stereo when an optional footswitch is connected, making the Dual Cube LX a self-contained jam station.

• Three-Band EQ: Bass, Middle, Treble — classic BOSS tone stack for shaping any amp type from clean to high-gain.
• Onboard Effects: 7 effects (4 modulation types + Heavy Octave + Delay + 2 Reverb types) — editable in depth via the DUAL CUBE LX Editor app.
• Looper: 90 s mono / 45 s stereo (requires optional footswitch) — lay down a chord progression and solo over it without a separate pedal.
• User Memories: 27 patches (3 per amp type) — store knob positions for instant recall between songs.

Connectivity, Power, and Portability — Practice, Stage, Studio, Stream

Connectivity is where the Dual Cube LX earns its LX designation. USB audio sends mix-ready guitar tones directly to a computer or mobile device for recording and livestreaming, while the i-CUBE Link/Aux In jack accepts stereo playback from phones and tablets. Stereo Line Out jacks with mic'd cab emulation feed a PA for live performance, and a Phones/Rec jack supports inline headphones microphones for vocal capture during streams.

• Power Supply: AC adaptor (DC 9 V, included) or 8 AA batteries — alkaline cells deliver approximately 8 hours of portable runtime.
• Bluetooth: Optional BT-DUAL adaptor slot — adds wireless audio streaming and remote editor control from iOS/Android devices.
• Footswitch Input: 1/4-inch TRS FOOT SW jack supports up to two external footswitches — for hands-free memory switching and looper control.
• Headphone Output: Stereo mini Phones/Rec jack (CTIA) — silent practice with full stereo imaging and inline-mic support.
• Dimensions: 341 mm wide × 162 mm deep × 215 mm tall — compact desktop footprint at 3.3 kg excluding the AC adaptor.

Who the Boss Dual Cube LX Is Built For

The Boss Dual Cube LX is the right choice for guitarists who need a single amp that covers bedroom practice, livestream sessions, and small-stage performances without swapping gear. Home players benefit from the eight amp types, three-band EQ, and silent stereo headphone practice; bedroom producers get USB audio and a 27-memory library for fast recall during tracking. Streamers and content creators can route vocals through the dedicated mic preamp type and capture both guitar and voice via the Phones/Rec jack and USB output. The Boss Dual Cube LX is also a strong fit for pedalboard players who want a true stereo FRFR platform, since the Stereo In amp type is voiced for modelers and stereo pedals from the factory.

The CUBE Legacy — Four Decades of Portable BOSS Amplification

The CUBE series has been a fixture in portable amplification since 1978, with over three million units sold worldwide across the Roland and BOSS lineup. The Dual Cube LX continues that lineage as the most feature-rich compact CUBE yet, carrying forward the indestructible build quality and instantly recognizable BOSS tones that defined earlier models like the Micro Cube. Its evolution adds modern essentials — USB audio, Bluetooth readiness, deep editor control, and a built-in looper — without sacrificing the grab-and-go portability that made the CUBE name synonymous with practice amps for generations of players.
