Natural Sound with Power, Definition, and Presence

Amplifying your acoustic guitar with the Acoustic Singer Live is an inspiring experience. BOSS engineers worked tirelessly to reproduce the instrument’s fast transient response and natural, three-dimensional feel. Each amplifier element was developed carefully to achieve this. A powerful bi-amp design with extended peak power delivers tight, high-definition sound with a clean broadband frequency response. The custom woofer and dome tweeter feature innovative materials. Their precision design fills the stage with rich, naturally diffused sound. The unique cabinet construction eliminates unwanted resonances, while the integrated tilt-back design enhances projection.

Guitar Channel with Acoustic Resonance

The Acoustic Singer Live’s guitar channel features a discrete analog input circuit that provides ample headroom for the quick attack and wide dynamic range of the acoustic guitar. Also included is BOSS’s Acoustic Resonance, which employs advanced processing to eliminate the hard, sterile sound produced by the piezo pickups in most stage guitars. This powerful feature not only enhances the character of your pickup but also restores the complex natural resonances that are so often lost when amplifying your acoustic. The channel provides a three-band EQ as well, plus a phase switch and notch control for keeping feedback issues at bay. Two types of chorus effects and a guitar-optimized reverb are also on hand to add a finishing touch to your sound.

Mic Channel for Vocals and More

The Acoustic Singer Live also includes a dedicated mic channel, providing singing guitarists with a compact, all-in-one amplification solution. It features a discrete analog input circuit for full, clear sound, and phantom power supports studio-grade condenser microphones. A three-band EQ, phase switch, and anti-feedback notch control are included. High-quality delay/echo and reverb effects enhance your vocal sound. If you're using the Acoustic Singer Live for guitar only, this channel can also be used to mic your acoustic. For advanced setups, it works well for blending another amplification source, such as a second pickup or internal mic.

Automatic Vocal Harmonies and Looping

A standout feature of the Acoustic Singer Live is its vocal harmony function, which creates live harmonies as you sing and play guitar. It all happens automatically, so there’s no complicated setup needed. Your chord progressions are analyzed in real-time, generating impressive harmonies perfectly tuned to the key of your song. And if you modulate to a new key, the intelligent processing follows along smoothly and accurately. Two different harmony types are available, plus a unison setting that doubles your voice for more impact. The amp’s built-in looper provides even more creative fun, allowing you to build live backing with guitar, vocals, effects, and more.

Advanced Connectivity and Control

The Acoustic Singer Live’s rear panel is well-stocked for your interfacing needs. Dual DI/Line outputs are provided on XLR connectors, and each features a versatile mode switch for outputting both channels mixed or individual channels direct or post-effects. There’s also an aux input with level control, perfect for playing backing music from your mobile device. A USB jack offers a direct computer connection to a DAW, while the Rec/Phones jack provides a standard ¼-inch stereo connection for quiet practice sessions or recording to portable devices. Numerous jacks are also available for controlling the harmony function, looper, effects, and more via optional footswitches.
