BOSS Acoustic Singer Live 60-Watt Acoustic Amplifier with Vocal Harmony and Looper

The BOSS Acoustic Singer Live is a professional 60-watt acoustic amplifier engineered for singer-guitarists who demand premium tone and creative versatility on stage. Featuring independent guitar and vocal channels, built-in vocal harmonies, a looper, Acoustic Resonance, and dual XLR DI outputs, it delivers everything an acoustic performer needs in a single compact package.

For anyone searching for the best acoustic amp for singer-guitarists, the Acoustic Singer Live stands apart by combining studio-quality amplification with performance tools typically reserved for separate rack units. The built-in vocal harmonizer analyzes your guitar chord progressions in real time and generates smooth, accurately tuned harmonies automatically — no complicated setup required. The integrated looper enables you to build live backing tracks with guitar, vocals, and effects on the fly, making it ideal for solo performers, duo acts, and any acoustic musician who needs maximum impact from minimal gear.

BOSS's Acoustic Resonance technology addresses one of the most persistent challenges in live acoustic performance: the hard, sterile character introduced by piezo pickups. Advanced processing restores the complex natural resonances that piezo systems strip away, returning your stage guitar to a sound closer to its true acoustic character. The 60-watt bi-amp design — pairing a custom 6.5-inch woofer with a 1-inch dome tweeter — delivers tight, high-definition broadband frequency response with rich, naturally diffused sound projection. A unique cabinet construction method eliminates unwanted resonances, and the integrated tilt-back design optimizes stage monitoring projection. The Acoustic Singer Live also functions as a USB audio interface for direct DAW recording, extending its value well beyond the stage.

Key Features of the BOSS Acoustic Singer Live

• 60-Watt Bi-Amp Design: Delivers powerful, high-definition stage sound through a custom 6.5-inch woofer (50W) and 1-inch dome tweeter (10W), filling the stage with rich, naturally diffused tone and ultra-clean broadband frequency response.
• Acoustic Resonance: Eliminates the hard, sterile sound produced by piezo pickups and restores the complex natural resonances of your acoustic guitar — the most important feature for any stage acoustic guitarist using a piezo-equipped instrument.
• Automatic Vocal Harmony: Real-time key and chord analysis of the guitar input drives smooth, accurate vocal harmonies with two harmony types plus a unison doubler — no manual key input or complex programming needed.
• Built-In Looper: Enables live backing track creation with guitar, vocals, and effects layered in real time, expanding creative possibilities for solo and duo performers without additional gear.
• Dual Independent Channels with 3-Band EQ: Discrete analog input circuits on both guitar and mic channels provide ample headroom and studio-quality sound, each with independent three-band EQ, anti-feedback notch control, and phase switch.
• Phantom Power and Combo XLR/TRS Mic Input: Supports studio-grade condenser microphones directly through the mic channel, enabling high-quality vocal amplification without an external preamp.
• Dual XLR DI Outputs with Mode Switching: Each DI output is independently assignable to individual channels (pre- or post-effects) or a combined mix, giving FOH engineers flexible signal routing options at any venue.
• USB Audio Interface Output: Direct computer connection via USB enables recording to any DAW with no additional audio interface required, adding studio functionality to a live performance tool.
