The Blackstar Sonnet is designed to amplify your guitar’s voice in the most natural and best way possible. It brings out the true character of your instrument’s tone with all the nuances created by your strums and picks. It’s the essence of an acoustic tone, but with enough projection for your gigging needs.

Hyperbolic as that might sound, you can bet you’re getting a serious rig when one Jon Gomm is involved in the design.

Fender Acoustasonic 40

While most other models on the list have 60 watts of output power, the Acoustasonic 40 from Fender will only hit a third of that. Not to say that it’s under-powered, though. If Fender’s long history in amp manufacture is anything to go by, 40 watts are more than enough to give your tone the on-stage presence it needs.

Indeed, the Acoustasonic 40 acoustic guitar amplifier disguises its sub-$200 price tag with a crisp, warm tone that immediately fills up the room. It’s not the most punchy, but there’s more than enough projection for your typical coffee house gig. Or maybe it’s a church performance? That shouldn’t be a problem either.

Fender Acoustasonic 15

Forget what we’ve just said. You don’t even need 40 watts to jack up your ax’s sound. The Fender Acoustic 15 can get the job done with just over a dozen. And at a cent short of a hundred, it’s about as cheap as a stage-ready mini acoustic amp can be.

Or is it really stage-ready? There’s no denying that this is designed primarily as a practice rig. With only 15 watts of output power, the sound barely registers in a decent-sized venue. But in a petite room in front of a small audience, the Fender Acoustic 15 could very well be the only piece of gear you’ll need — besides your acoustic guitar, obviously.

Highlights

  • 15W Dual-Channel Solid State Amp with 1 x 6-inch Speaker

With its potent built-in speaker and lightweight build, the Fender Acoustasonic 15 is ideal for guitarists who like to jam on their travels. It’s proof that a decent small acoustic guitar amp needn’t cost a king’s ransom.

BOSS Acoustic Singer Live LT

Once upon a time, you could plug into any black DI box you happened upon and have no qualms with the sound. But now that you’ve upgraded to a finer ax — and spent way too much time perfecting your strums and picks — you can’t afford to be so laissez-faire. You need a pro-grade amp that can coax the best sound possible out of your acoustic guitar. An amp like the compact Acoustic Singer Live LT from BOSS.

Highlights

  • Solid-state Combo Amp; 60W Bi-amp design with custom 6.5″ Woofer and 1″ Dome Tweeter
  • Input: 1 x 1/4-inch Instrument, 1 x 1/8-inch TRS (stereo aux), 1 x XLR

  • 3-band EQ
  • Effects: Reverb, Echo, Delay & Enhance (mic channel); Chorus, Delay & Reverb (guitar channel)
  • Anti-Feedback Notch Control
  • Power: Standard AC Cable
  • Weight: 22.5 lbs

Featuring a bi-amp engine under the hood and a full-range speaker, the ACS-LIVE LT yields a crisp, high-definition tone that reflects the true abilities of your acoustic guitar and voice. It packs all the tools you need to shape your sound just right and set the stage alight. It’s so well-equipped, in fact, that you could dispense with your sound engineer. Yet, the control layout’s simple enough to navigate comfortably on a dimly-lit arena. And while the price does seem a tad out of reach, you can bet on the BOSS Acoustic Live LT to justify every penny it costs.

Marshall AS50D

Ready to rock your next gig with a bona-fide compact Marshall rig? No, not the one you’re thinking — a hundred-watt tube combo is way too much amp for your typical performance. Instead, you want a more-restrained unit that will inject just the right amount of oomph into your tone without turning it upside down. A box that has all the tools and tricks you need without being overly-complicated.

That’s exactly what the Marshall AS50D has to offer. Its custom speakers and tweeter combo yields a well-rounded tone that, thanks to the 50W output, is potent enough to cover small and mid-size venues. Two channels with independent volume and EQ controls let you keep things in control, and there’s a handy anti-feedback feature to help you rein in errant frequencies.

Highlights

  • 50W Dual Channel Solid State Combo Acoustic Guitar Amp
  • 2 x 8-inch Celestion Speakers, Polymer Dome Tweeter
  • Inputs: 2 x 1/4-inch Hi Instrument, 2 x RCA Low Line Level, 1 x XLR
  • Outputs: 1 x 1/4-inch Mono Line Level, 1 x XLR DI-out
  • EQ: Dedicated Bass & Treble controls for each channel
  • Master Volume Control
  • Effects: Onboard Chorus & Reverb; Parallel FX Loop (External)
  • Frequency Sweep for Feedback Control
  • Power: AC Adapter
  • Weight: 35.3 lbs

While it won’t get as many headlines as its valve-driven stablemates, the Marshall AS50D is bound to appeal to a wide range of players. It’s the perfect fit for the contemporary acoustic guitarist who wants an amp that’s both capable and practical.

Best Mini Small Acoustic Amps Conclusion

Granted, the amplifier is nothing more than a means to step up the voice of your guitar. If you’re looking to buy one of these rigs in the hope that it’ll improve the tone somehow, perhaps you should channel your best efforts elsewhere. An average acoustic guitar will still sound mediocre no matter what you plug it into.

Of course, plugging a well-built, properly-voiced acoustic guitar into a sub-par rig will inevitably sour the sonic yield. As we highlighted, this isn’t something you want to take for granted after making so many sacrifices to get your dream acoustic guitar — and sharpening your skills over endless practice sessions. The point here is that you need to keep your expectations realistic while shopping; do so and you’ll seldom be disappointed with your best choices.
