Great power and features for small- and medium-sized gigs.

The ACS Live takes the acoustic stage amp to new levels of sound quality and creative versatility. Incorporating BOSS’s latest advancements in amplifier research, this compact powerhouse produces rich, vibrant sound with unmatched punch and clarity. Independent channels are provided for acoustic guitar and vocal, and each is equipped with discrete analog input circuits and three-band EQ for studio-quality sound. And with additional features such as Acoustic Resonance, looping, automatic vocal harmonies, effects, and much more, the ACS Live gives acoustic musicians everything they need to deliver inspiring and impactful live performances.

Natural Sound with Power, Definition and Presence
Amplifying your acoustic guitar with the ACS 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 ACS 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 ACS 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 ACS 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 ACS 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 ACS 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-in. 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.

Comments about Boss Acoustic Singer Live 60W 1x6.5 Acoustic Guitar Amplifier:

Was looking at portable PAs for my guitar/vocals duo - jazz, folk, Americana, originals, etc. My partner has an incredibly powerful voice and I need a way to keep up with her in the small, often unamplified venues we play - coffee houses, small clubs, house concerts, etc. I am CRAZY picky about guitar tone and sound quality and I'm always complaining about the thin, overly bright tone quality of most acoustic guitar pickup/amp combos. This amp solves that problem and then some.

Even the smallest stick PA like the FIshman 330x and Bose L1 are too cumbersome for us. I really wanted something that I could set up in 30 seconds and go. With this little guy you pull up a stool, plug it in and you're in business. The reverb and chorus are lush and full. Hit the tweeter attenuator switch and all that nasty piezo clack is gone. Lows are freakishly smooth and deep for a 6" woofer, and it hasn't bottomed out yet. On a stool, all controls are in arm's reach and clearly labeled. It's super easy to get amazing, professional-sounding tone, and it gets quite loud. It's so great, I'm thinking of getting my partner her own.

With two of them we could fill quite a large place. And to be clear, I'm talking about the little 6.5" woofer 60 watter - Boss Acoustic Singer Live, not the Pro. With the 120-watt Pro you'll get an 8" woofer another 3dB, but the size increases from roughly 12" x 14.5" x 11" to 14" x 17" x 13" (HxWxD), and weight jumps from 23 to 32 lbs. This little guy is almost exactly the same size at the Fishman Loudbox Mini except with 48v phantom power, dual assignable XLR outs, onboard harmonizer and built-in looper.

With two of these babies we'd have four channels - 2 vox and 2 guitar. If we need more than that it's on the venue or we'll rent a Fishman 330x stick PA. Even then, I'm still bringing the Boss, the tone is to die for. We have a gig tonight where they have a nice house PA and I'm still bringing it. I think their soundman will be impressed.
