    Bi-Amp Design

    Boss Acoustic Singer amps utilise bi-amplification for accurate, full-range response. Combined with the Pro 8” custom woofer and dome tweeter and the result is a powerful and resonant sound that’s clear across the frequency spectrum. Ideal for getting natural-sounding acoustic guitar and vocal tones.

    Separate Channels and Effects For Guitar and Mic

    As the name suggests, the Acoustic Singer is designed for acoustic guitarists who double up as singers, whether that’s in the context of a band, or as a solo singer-songwriter. This amp has both guitar and microphone channels with separate inputs, EQ, and effects for each. The independent three-band EQs on each channel allow you to dial in the perfect tone for guitar and vocals without one compromising the other. The mic channel also has phantom power so you can use studio-grade condenser mics with it. If you’re not a singer then you can use the mic channel to run an external or internal microphone through allowing you to blend it with a piezo or soundhole pickup

    You also get built-in effects to add a little extra life to the amped sound. On the mic channel you get Reverb and Delay/Echo, as well as an “Enhance” function to help you achieve bigger, richer sounding vocals. On the guitar channel you get Reverb and Delay/Chorus controls for “in-the-room” or ambient sounds, as well as an Acoustic Resonance switch for countering the flatness that can come from using a piezo pickup.

    The Live and Pro versions of the Acoustic Singer feature the vocal harmony function. This function automatically creates harmonies as you sing by analysing your chord progressions, and will even adjust if you change key. You get two different harmony settings as well as a unison setting for doubling up your voice. These versions also have built-in loopers so you can be your own band and build up a backing track live to perform over.

    Features and Functionality

    The bane of every acoustic performer is, of course, feedback. The Acoustic Singer has a built-in Phase switch to ensure you’ll always be in phase, as well as an Anti-Feedback control that allows you to isolate and eliminate the unwanted frequency.

    The Acoustic Singer is a great amp but it does more than just amplify your guitar and voice. At 120-watts, the Pro is great for medium-sized performances, but if you need to play larger venues just use the XLR DI output to hook up to a PA system. This amp is footswitchable (footswitch not included) so you can have functions like harmony, looping, effects, and more at your quick disposal. You can play along to backing tracks with the Aux input (with line control), and there’s a 1/4” jack for headphone use or recording to mobile devices. For recording direct to a DAW there’s a USB jack as well.

    Great bit of kit - it would get 5 stars if the foot switch would also toggle between the three vocal harmonies. The sound is amazing for such a compact unit.

    Awesome. Just awesome. Great sound for a smallish amp. Looper is easy to use. Harminies on mic are fun.

    Mr L Beardsley3rd Jan 2019

    Really superb bit of kit. Sound is phenominal and ease of use excellent. Looper is best (easiest) I've tried (shame it doesn't save stuff). Harmoniser almost makes a singer out of me! Would highly recommend.

    My choice was after trying a few similar amps in stores (is there a future for online, best-buy options to have some 'demo stores' on high streets?)
