The Acoustic Stage Amp - Redefined!

The Acoustic Singer Live is a stage amp with unprecedented sound quality and versatility. Equipped with the latest BOSS amplifier developments, this compact powerhouse delivers a rich, lively tone with unmatched punch and clarity.

The Acoustic Singer Live features independent channels for an acoustic guitar and a microphone, both with discrete analog input circuitry and a three-band EQ for studio-quality sound. With additional features such as Acoustic Resonance, a looper, automatic vocal harmonies, effects and more, the Acoustic Singer Live gives acoustic musicians everything they need for inspiring and impactful live performances.

Natural Tone With Power, Definition and Presence

Amplifying your acoustic guitar with the Acoustic Singer Live is an inspiring experience. BOSS engineers worked tirelessly to design the amplifier so it reproduces the instrument's natural transients and its three-dimensional tonal character. Every component of the amp was developed with that goal in mind.

A powerful bi-amp design with extended peak power delivers tight, high-definition sound with an ultra-clean, wideband frequency response. The proprietary subwoofer and tweeter are made from innovative materials and envelop the stage in a rich, naturally diffuse sound. Another key detail is the unique cabinet construction that eliminates unwanted resonances and an internal rear-wall design for maximum projection.

Guitar Channel With Acoustic Resonance

The guitar channel on the Acoustic Singer Live features a discrete analog input circuit that preserves fast attack and the acoustic guitar's dynamic breadth. It also includes BOSS Acoustic Resonance, whose advanced processor compensates for the harsh, sterile tone of the piezo pickups found on most stage guitars.

This powerful feature not only enhances your pickup's tonal character but also restores the complex natural resonances that are often lost when amplifying an acoustic guitar. The channel also offers a three-band EQ, a phase switch and a notch filter to minimize feedback issues. Finally, two chorus effects and a guitar-optimized reverb are integrated to give your sound the finishing touch.

Microphone Channel for Vocals and More

Besides the guitar channel, the Acoustic Singer Live also has a microphone channel, making it the all-in-one solution for singing guitarists. The discrete analog input circuitry delivers a clear, full sound. Phantom power enables the use of studio-quality condenser microphones.

This channel is also equipped with a three-band EQ, a phase switch and a notch filter, and the vocal sound can be enhanced with first-class delay/echo and reverb effects. If you use the Acoustic Singer Live for the guitar only, the guitar can also be mic'd through this channel. In elaborate recording setups, the second channel is useful for blending in the sound of an additional pickup, such as a second pickup or an onboard microphone.

Automatic Vocal Harmonies and Looper

A standout feature of the Acoustic Singer Live is its Vocal Harmony function, which generates harmonies live while you play and sing. It works completely automatically, with no complicated setup required. Your chords are analyzed in real time, impressive harmonies are generated and seamlessly integrated into your performance.

Even when you change key, the processor adapts the sound harmonically and seamlessly. Two different harmony types are available, plus a unison setting that doubles your voice for more presence. The built-in looper lets you accompany yourself live with guitar, vocals and effects, adding extra fun.

Expanded Connectivity and Control Options

On the rear of the Acoustic Singer Live, two DI/line outputs with XLR connectors and a versatile mode switch for combined output of both channels or separate output with or without effects cover all interface requirements. There's also an AUX input with a volume control for playing backing tracks from your smartphone, for example.

A USB port enables direct connection to a DAW, the Rec/Phones jack is a standard stereo phone jack to which headphones or a portable recorder can be connected. Additional jacks allow control of the harmony function, looper, effects and more via optional footswitches.

A wonderful toy for those hours alone at home. I don't mean that in a derogatory way! The guitar channel is perfectly laid out, all my acoustic guitars come beautifully acoustically 'rüber. But not only at home. I play live with it, i.e. the boss is my monitor, line into the mixer and the perfect sound is there.
The vocal channel, on the other hand, is really more for home use. A dynamic mic unfortunately overloads before you reach a reasonable volume. But with the harmonizer practicing is really fun! In retrospect, I would recommend the big brother, which certainly has enough power to actually exist in a pub, the small creates that unfortunately not.

Question by Renk on 10.11.2017

Can you use the foot switch Boss FS.5U for the Boss ACs-live Acoustic Singer Live amplifier .For example to change the vocal harmonies ? Thanks in advance .
Kind regards Ehrenfried Renk

Answer by Musikhaus Kirstein:

Loop start - stop rather the 00037692 Boss FS-7U, otherwise you always have to step on it 2 x. For the harmony changes, the 5U is enough so the small.
