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 1/4-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.

Great sounding amp


This amp sounds amazing and loud. Kinda pricey but worth it.



Good size


Good sound, easy on the weight



Better Features Than The Competition.


The features of this amp, Harmonizer and Looper is what attracted me to this amp. The other features is the acoustic resonance, chorus 1/2, anti feedback with delay and echo on mic input, phantom power that finalize my decision to go with amp.




Better than the competition........


Definitely a much better choice than the other acoustic amps out there. The features on this amp is all you need. Jeff @ San Diego store is the best.




I almost got a Fishman, but Boss won me over!


This is the first Acoustic amp I've ever purchased and I'm so happy with it! I've been playing guitar for 15 years, and jam on both electric and acoustic. I started singing about a year ago, formed a band, and am taking this amp out to our first show tonight! We're gonna make a live recording of the show and put those dual DI outputs to use. Features that I dig: - the 3 acoustic resonance tones seriously improve the sound - The equalizers for both mic and guitar offer incredible flexibility of your sound and are easy to use on the fly - the loop pedal! It's simple and so much fun! - the vocal harmonizer is insane. Just watch some videos and you'll see what I mean. - the portability... And this sucker is pretty dang loud for it's size! The same day I bought this amp, I also tested and nearly picked up a Fishman charge (also a cool amp with it's own neat features!) ... Personally, I liked the Boss's features more, but would recommend giving the Fishman a try. Both amps sound fantastic and are comparable in price... To me it came down to features and Boss won out for my tastes.



I would recomend this Amplifier to anyone for any ocasion.


Another great purchase through Sam Ash Music. Beautiful Acoustic, as well as, vocal sound provided through this ACS-LIVE Acoustic Singer Live 60-Watt Acoustic Guitar Combo Amplifier.



One amp! 2 different outputs! Less gear to haul! Great tone!


This bad boy is full of surprises! The looper is beyond easy to use and the vocal harmonizer adds so much texture to the vocals. 60 watts goes a lot farther than you would think. I'm in a 2 piece acoustic project that just played a brewery with over 130 people present. We ran the mic output and instrument output into 1 JBL Eon 15. We had to turn it down. I'd say this amp is perfect without additional gear for intimate settings in venues like coffee shops, small restaurants and pubs. I compared this next to the fishman products and liked this one much more!
