What we say:

The Acoustic Singer Live is a compact but powerful acoustic combo for performers who sing and play guitar together and require a high quality one-box solution for performing live.

This feature-rich amplifier gives out 60 watts of power which should be more than enough for smaller acoustic gigs. There are two channels, one for voice and one for guitar, each with it’s own dedicated EQ and specific controls. The guitar channel gives you useful features like chorus, reverb and an Acoustic Resonance control for bringing a little bit of ‘natural’ tone to piezo-equipped guitars. The mic channel has delay/Echo, an separate reverb, an anti-feedback notch filter and phantom power for using condenser mics.

Relative to them both are the Harmony and Looper sections. These are both footswitchable (available as optional extras) or operable from the front panel. The Harmony section takes harmonic information from your guitar chords and supplies a low, unison or high harmony that accurately corresponds and relates to your singing and playing. It’s most impressive!

The looper is something that Boss are deservedly renowned for: their RC units are arguably the most popular loopers in the world! Looping really opens up solo performances and allows you to be creative with your writing, arranging and performing. Together with the harmony section, you can build up some very complicated pieces of music on the fly.

The key here is quality: the mic preamp is great, the Acoustic Resonance control can really get some realistic tones from your guitar and the effects are all top-notch. In short, it’s like having a good sheen of decent production on your entire performance, set up and regulated by you!

Even the outputs are comprehensive: there are two balanced XLR outs for occasions when a large PA is required (the Acoustic Singer Live can then act as a preamp and a monitor) and a USB out for going straight into your laptop. Boss have thought of everything you could need apart from a guitar, a voice and some great songs.

Natural Sound with Power, Definition, and Presence
Amplifying your acoustic guitar with the Acoustic Singer Live is a truly inspiring experience. BOSS engineers worked tirelessly to accurately reproduce the instrument’s fast transient response and natural, three-dimensional feel, and each amplifier element was carefully developed to achieve this. A powerful bi-amp design with extended peak power delivers tight, high-definition sound with ultra-clean broadband frequency response. The custom woofer and dome tweeter feature innovative materials and precision design points that work together to fill the stage with rich, naturally diffused sound. Other fine details include a unique cabinet construction method that eliminates unwanted resonances, and an integrated tilt-back design for maximum 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, giving singing guitarists a compact, all-in-one amplification solution. A discrete analog input circuit delivers full, clear sound, and phantom power is on tap for using studio-grade condenser microphones. There’s also a three-band EQ, phase switch, and anti-feedback notch control, plus top-quality delay/echo and reverb effects to enrich your vocal sound. If you’re using the Acoustic Singer Live for guitar only, this channel can alternately be used to mic up your acoustic. For players that use advanced setups, it also works great for blending another amplification source installed in the guitar, such as a second pickup or an 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 together, 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.
