Boss Acoustic Singer Pro 120-Watt Acoustic Combo Amplifier
A complete live performance system for singer-songwriters — 120 watts of bi-amped clarity with built-in vocal harmonies, looping, Acoustic Resonance, and pro-grade outputs in one road-ready package.
Who This Amp Is Built For
If you play acoustic guitar and sing — and you want to walk into a gig with one amp and walk out having delivered a full, polished performance — the Boss Acoustic Singer Pro was engineered specifically for you. It handles your guitar channel and vocal channel independently, each with its own three-band EQ and effects, so you are never fighting the same knob for two different sources. The bi-amp design pushes 100 watts to the woofer and 20 watts to the tweeter, giving acoustic instruments the fast transient response and natural body they need to cut through a room. Whether you are performing at a coffee house, an outdoor festival, a private event, or a small theater, this amp brings a level of built-in intelligence that used to require a rack full of outboard gear. The automatic vocal harmony function follows your chord changes in real time, the onboard looper handles both channels simultaneously, and dual XLR DI outputs let you send a clean signal directly to front-of-house without a separate DI box. The integrated tilt-back design aims projection exactly where you need it, and the USB output lets you capture your performance straight to a computer. For the working solo artist who needs reliability, tone, and creative tools without the complexity, this is a remarkably complete solution.

Why You'll Love It
Features That Work Together
Everything on this amp was designed with the solo performer's workflow in mind. The guitar channel feeds the harmony engine in real time, so you are never programming keys or tapping in tempos — just play, and the harmonies follow. The looper captures both guitar and vocal simultaneously, which opens up creative possibilities that most single-channel loopers simply cannot match.
Tone That Holds Up Live
Acoustic Resonance processing addresses one of the most common complaints from stage acoustic players — the thin, brittle sound of a piezo pickup. Boss's processing restores the complex natural resonances that piezo transducers strip away, giving your instrument a warmer, more three-dimensional tone without external pedals. The reverb on both channels is notably smooth and musical for a combo amp at this price point.
Practical Stage Engineering
The dual XLR DI outputs give sound engineers two clean, post-effects signals to work with — one for each channel — or a combined mix, depending on what front-of-house needs. The USB output lets you record your set directly without an audio interface. At 32 pounds with an integrated tilt-back design, this is a gigging amp that was clearly thought through from load-in to soundcheck to performance.
Great Fit For
- Singer-songwriters performing solo with acoustic guitar and vocals
- Working musicians who need a reliable all-in-one solution for small to medium venues
- Performers who want real-time vocal harmonies without a separate pedal or processor
- Artists who build loop-based live performances using both guitar and voice
- Musicians who send a direct signal to front-of-house and need clean, professional DI output
- Recording artists who want to capture live sets directly to a computer via USB
- Players with under-saddle piezo pickups who want to restore natural acoustic tone on stage
Sound and Use Case
The Acoustic Singer Pro occupies a specific and valuable space — it is not a general-purpose PA, and it is not a traditional acoustic amp. It is a purpose-built performance tool for the solo acoustic artist. The guitar channel is voiced for warmth and detail, with an EQ that is broad enough to compensate for a wide range of pickup types and room acoustics. The Acoustic Resonance control is a genuine tonal asset, particularly for players using under-saddle piezo pickups, which often sound harsh or lifeless through a neutral amplifier.
The vocal channel delivers clear, full reproduction with enough gain for both dynamic and condenser microphones. The delay effect on the mic channel provides two distinct echo characters in a single control, and the reverb is smooth and depth-adding without washing out intelligibility. When the harmony function is engaged, it tracks diatonic harmony within the key established by your guitar input, updating naturally as you move through chord progressions. The overall sound character is clean and detailed — this is an amp designed to let acoustic instruments sound like themselves, only louder.
Specifications
There is something genuinely satisfying about watching a solo performer walk in with one amp, set up in ten minutes, and deliver a show that sounds like they brought a whole production crew. That is what the Acoustic Singer Pro makes possible — and it does it consistently, night after night, without asking a lot of you in return.
If you have been wrestling with a separate vocal processor, a pedalboard of effects, and a DI box that never quite matches what you hear on stage, this amp might be the piece that simplifies everything. We have seen it connect with players at a lot of different levels, from weekend coffeehouse performers to working touring artists who needed to lighten their load.
