Get A Powerful Stage Companion With The Boss ACS-PRO Acoustic Singer Pro Acoustic Amplifier

The Acoustic Singer Pro 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 Acoustic Singer Pro 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 Acoustic Singer Pro 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 Pro'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 Vocal And More

The Acoustic Singer Pro 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 Pro 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 Pro 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.
