Boss Dual Cube LX — Stereo Desktop Power for Guitarists

The Boss Dual Cube LX is a 10-watt stereo desktop guitar amplifier built for players who want serious tone in a compact, go-anywhere format. Two custom 4-inch speakers and a 5W+5W stereo power stage produce full, immersive sound that belies the amp's small footprint. Practicing at home, jamming with friends, streaming online, or playing a small stage—this desktop powerhouse adapts to nearly any scenario. Guitarists who need a portable amp with pro-grade connectivity and authentic BOSS amp modeling will find it a strong match for everyday playing.

What Sets the Dual Cube LX Apart

Within this category, the Stereo In amp type is rare—it accepts stereo signals from modelers and pedalboards and applies spatial processing for an expansive soundstage. A dedicated mic preamp turns the unit into a portable vocal PA, with mic'd cab emulation on the stereo line output. Onboard looper functionality offers 90 seconds of mono or 45 seconds of stereo recording, operated by an optional FS-series footswitch.

Amp Modeling and Onboard Effects

Eight amp types—Acoustic Sim, JC Clean, US Combo, Brit Combo, Hi-Gain Stack, Metal Stack, Extreme, and Mic—cover a range of clean, crunch, high-gain, acoustic, and vocal needs. With two variations for each voicing and three user memories, instant recall is at your fingertips. Seven onboard effects are available: chorus, flanger, phaser, tremolo, heavy octave, delay, and two reverbs. Deep editing is possible through the DUAL CUBE LX Editor for iOS, Android, Windows, and macOS.

• Amp Types: 8 guitar voicings + 1 mic preamp — covers clean, crunch, high-gain, acoustic, and vocal use
• For effects, you can shape your tone with chorus, flanger, phaser, tremolo, heavy octave, delay, reverb, and spring. Each is deeply editable.
• Memory Slots: 27 (3 per amp type) — instant recall

Battery-Powered Stereo Performance

The 10W stereo power stage drives two custom 4-inch (10 cm) speakers, producing punchy tone from a 341 × 162 × 215 mm enclosure weighing 3.3 kg. Eight AA batteries deliver roughly 8 hours of alkaline runtime or about 10 hours with Ni-MH rechargeables, making it genuinely portable for street performance or outdoor sessions.

• Rated Power Output: 10 W (5 W + 5 W stereo)
• Custom-designed 2 × 10 cm (4-inch) speakers create a wide stereo image from a compact desktop enclosure.
• Battery Life: ~8 hours alkaline / ~10 hours Ni-MH — true cable-free playing on eight AA cells

Pro-Grade I/O for Stage, Studio, and Stream

Stereo line outputs with mic'd cab emulation can feed a PA, while the USB-B port enables plug-and-play recording and livestreaming without extra drivers. The i-CUBE Link/Aux In jack accepts playback from phones and computers, and an optional BT-DUAL adaptor adds wireless audio streaming plus Bluetooth MIDI control. Front-panel controls include Amp Type, Gain, Volume, Bass, Middle, Treble, Effects, Delay/Reverb, and Master knobs for hands-on sound shaping.

• Footswitch Input: 1/4-inch TRS, supports up to 2 FS-series switches — hands-free looper and memory switching
• Headphone output supports stereo mini plugs and inline mic for recording or monitoring in private.
• Bluetooth: via optional BT-DUAL adaptor — wireless audio streaming and remote editor control from a phone or tablet

Who Should Choose the Dual Cube LX

Home players looking for studio-quality amp modeling without room-filling gear will appreciate this amp. The Dual Cube LX is well suited for guitarists who want a portable, battery-powered unit that also serves as a USB audio interface and streaming hub. Content creators will benefit from headphone mic support and USB Loopback for capturing both guitar and voice in one take. Pedalboard users with stereo modelers like the GT-1000 or GX-100 gain a dedicated Stereo In voicing that does justice to their rigs.

The CUBE Legacy Since 1978

The CUBE series has been a portable amp staple for over four decades, with more than three million units sold worldwide since the first model launched in 1978. BOSS has continually refined the formula — rugged enclosures, long battery life, and amp modeling that punches above its weight. This latest evolution delivers pro I/O and wireless features in a desktop format that fits on a desk, kitchen table, or busking setup.
