The natural tone of an acoustic guitar is one of the most simple, elegant, and beautiful sounds in music. But acoustic instruments were designed in an era before the prevalence of what we not consider the “full band” setup—i.e., bands with drums. 

So it’s understandable to want to amplify your acoustic for jam sessions or gigs—especially when competing with drums and electric guitars or keyboards. But if you’re thinking about plugging your acoustic-electric guitar into your Marshall JCM900 or Fender Deville, just—don’t, okay? Trust me.

Instead, opt for an acoustic guitar amp that’s designed explicitly for the purpose of amplifying your acoustic guitar’s natural tone, without distorting, feeding back, or otherwise corrupting your signal. With one of our picks for the best acoustic guitar amps, you’ll amplify your guitar’s natural tone—rather than just having it sound exactly like your Gibson SG does when plugged into your half-stack.

In many cases, you’ll also get additional tone-shaping options like EQ and reverb, and many of today’s best acoustic guitar amps are designed with vocalists in mind, providing all-in-one acoustic amplification and vocal processing, making them ideal for buskers and traveling solo performers.

How I Picked (and Why Trust Me?)

I’m a singer, songwriter, and guitarist with over 20 years of experience playing live and recording. My first instrument was an acoustic guitar, which I got when I was about six years old.

Today, I play country, bluegrass, folk, and rock, gigging both solo and with a band, and the acoustic guitar is still my primary instrument.

I’ve picked out a wide range of acoustic guitar amplifiers, keeping in mind a number of factors including portability, budget, effects and features, power rating, and aesthetics. Whether you’re playing with a full band, gigging solo, or just jamming out at home, you’ll find the best acoustic amp for your needs in this guide.

Let’s check ‘em out.

Best Acoustic Guitar Amps

1. Best Overall – Fishman Loudbox Artist BT

SPECS

• Number of channels: 2
• Speakers: 1 x 8" woofer, 1 x 1" soft dome tweeter
• Effects: Delay, Echo, Chorus, Flanger, 2 x FX loops
• Output: 120W
• Weight: 25.5 lbs

From the best-known name in acoustic guitar electronics comes the Fishman Loudbox Artist BT. Boasting two channels, a hefty helping of controls and connectivity, and 120 watts of room-filling power, all for well under a grand, the Loudbox Artist is a no-brainer for the best overall acoustic amp in my opinion.

You can't go wrong trusting a brand that's dedicated to acoustic guitar amplification. And with the Loudbox, Fishman pulled out all the stops. You get two channels of 120W power, with one channel intended for acoustic instruments and the other for vocals. Each channel has 1/4"/XLR combo jacks to accommodate both instrument inputs and microphones (there's even phantom power for condenser mics), and they each have a smattering of controls including gain, EQs, and an easily switchable FX menu.

The connectivity is really the name of the game here, though. Aux input, Bluetooth pairing capability, and a balanced XLR DI output (you're going to need this if you plan to play in a venue with a proper sound system) means this amp can handle just about any situation imaginable.

As an acoustic guitarist, the main thing I want is that my guitar's tone comes across sounding natural and accurate, and I can attest that the Loudbox does exactly that. If you're looking for pure acoustic tone in a lightweight, versatile, easy-to-use, and relatively affordable package, you can't go wrong with the Fishman Loudbox Artist BT. Looking for more (or less) power with the same features? Fishman also makes the Loudbox in Micro (40W), Mini (60W), and Performer (180W).

Reasons to Avoid:

• Could be overly complicated for some

2. Best Acoustic Guitar Amp Under $500 - Fender Acoustasonic 40

SPECS:

• Number of Channels: 2
• Speakers: 2 x 6.5" speakers with whizzer cones
• Effects: Digital hall reverb, 3-band EQ
• Output: 40W
• Weight: 16.5 lbs

While Fender isn't best known for making acoustic guitars, they do make a mighty fine amp. And the Acoustasonic 40 makes an example of Fender's fine amp-building acumen, applied to the acoustic realm.

Similarly to Fender's best-known electric guitar amps, the Acoustasonic is light on bells and whistles, favoring instead a simple, easy-to-use design that's deceptively big on sound. Two channels with combo-jack inputs allow you to hook up a guitar and a mic (just like the Fishman Loudbox), and a 3-band EQ + digital hall reverb allow you to dial in a good sound without too much distraction.

Two specially-designed 6.5" whizzer speakers faithfully reproduce your guitar's sound, and there's an XLR line output for use in a live setting. While 40W is a lot less power than some other options on this list, it's actually plenty for many scenarios, like jamming at home or small cafe gigs.

Best of all, this lightweight amp is super affordable, coming in at under $300 at time of writing. If you're looking for a solid plug-and-play acoustic amp option that won't break the bank, I recommend picking up a Fender Acoustasonic.

Reasons to Avoid:

• Some might need more power

3. Most Portable - Positive Grid Spark GO

SPECS:

• Number of Channels: 4 x Programmable Presets
• Speakers: 1 x 2"
• Effects: 43 x Built-in FX: Distortion, Modulation, Delay, Compressor, Noise Gate and more ; Spark App FX expansion
• Output Power: 5W
• Weight: 0.76 lbs

Now for something a bit different. Positive Grid's Spark GO takes PG's proprietary modeling and app integration and packs it into their tiniest chassis yet, leveraging a single 2" speaker to surprisingly powerful effect.

Any Positive Grid device is going to give you basically unlimited amp modeling and effects capabilities, plus a killer Bluetooth speaker to boot. But if you're looking for a pocket-size amp to give your acoustic playing a little extra boost while traveling around, you've found it.

I typically dissuade acoustic players from oversaturating their tone with effects—the whole point of acoustic amps is to amplify your acoustic tone—but you can get a great clean tone and add reverb, EQ, and so on with this little amp, and so it really makes a nice fit for acoustic players as well as electric.

This versatile tool is well worth the money, especially for acoustic players who also go electric. Whether amplifying your acoustic, throwing on some headphones and diving into the Spark app, or just streaming some tunes while kicking back, the Positive Grid Spark GO is a perfect traveling companion.

Reasons to Avoid:

• Not for those seeking a conventional amp

4. Most Stylish - Taylor Circa 74

SPECS:

• Number of Channels: 2
• Speakers: 1 x 10" speaker
• Effects: 2 x 3-band EQ, Reverb
• Output Power: 150W

If you've got a bit more dough to spare and you're looking for a classy conversation piece for your jam room, the Taylor Circa 74 is the acoustic amp for you. It's got a lot of the same features as the other amps on this list, including 2 channels, a 3-band EQ, and Bluetooth connectivity, but it was designed with aesthetics to match your most stunning acoustic instrument.

An all-mahogany cabinet and included stand (Koa also available) makes the Circa 74 stand out from the bunch, visually speaking, with a midcentury modern flair that might even convince your wife to let you keep it in the living room.

But it's not all about the looks here—Bob Taylor himself had a hand in ensuring this amp provides the most sonic clarity and warmth possible, dialing back what he considered to be an excessive amount of treble in faithfully reproducing acoustic tone, favoring instead a warmer, deeper sound that's richer and less quacky or snappy than you might get elsewhere.

It's got one XLR input for hooking up a mic, a simple control panel, and a nice leather handle for carrying. But I personally wouldn't want to take mine out of the house, for fear of banging up that beautiful mahogany.

Reasons to Avoid:

• Small enough to carry; but not ideal for gigging if you don't want to bang it up

5. Best for Solo Performers - Boss Acoustic Singer Live

SPECS:

• Number of Channels: 2
• Output Power: 60W Bi-amped
• Speakers: 1 x 6.5" Woofer, 1" Dome Tweeter
• Effects: Reverb, 3-band EQ, 2 x Chorus (guitar), Delay/Echo (mic), Harmony (mic)
• Weight: 23.18 lbs

If the name doesn't make it clear enough, the BOSS Acoustic Singer Live was designed for acoustic guitarists/singers to perform... live. In fact, it's an acoustic guitar amp with advanced signal processing, delivering the power of the venerated BOSS VE-8 Acoustic Singer effects processor pedal, but packed into a chassis with 60W of power and a custom 6.5" speaker (with 1" dome tweeter).

As with most acoustic amps, there's an emphasis on accurate reproduction of your guitar's (and your voice's) natural tone, in this case relying on a bi-amped custom 2-way speaker system to preserve warmth and clarity. Add to that BOSS's acoustic resonance processing, which works to counteract the negative effects of piezo pickups (commonly employed on electric-acoustics), restoring more of the your guitar's natural sound.

And for vocalists, the Acoustic Singer Live comes jam-packed with features that will liven up any solo performance. Automatic harmonies, a looper, and tons of effects give you the full power of BOSS's Acoustic Singer pedal, so you can sound your best even when performing with nothing more than your acoustic guitar.

Just a couple more unique features that make the Acoustic Singer Live a really compelling option for performers: first, a USB interface that allows you to record directly out of your amp into a computer or USB recording device (love that). And second, separate lines out for vocal and guitar that make using this amp in a live setting that much easier on the sound engineer. And, as we know—a happy sound guy is a lot more likely to give you that "one more song."

Reasons to Avoid:

• Don't bother with this one if you're not a vocalist

6. Best for Beginners - Fender Acoustic 100

SPECS:

• Number of Channels: 2
• Output Power: 100W
• Speakers: 1 x 8" speaker with whizzer cone
• Effects: 3-band EQ, 3 x Reverbs, Delay, Chorus, Vibratone
• Weight:17.6 lbs

Fender's Acoustic 100 boasts a clean aesthetic and simplified control panel that makes it not only visually appealing but easy to use as well. Beginners who aren't already steeped in the realm of effects processing will have no trouble getting the hang of dialing in their sound with the use of the effects toggle knob and level adjustment. And it's a lot of functionality at what is effectively a beginner price point, making it a compelling pick for a first acoustic amp.

The Acoustic 100's attractive plywood chassis makes it second only to the Circa 74 in terms of visual appeal, in my opinion. Fender's clean, midcentury-inspired design aesthetic is evident in spades, and the use of blonde wood lends it a vaguely Scandinavian appeal that will allow it to look at home even if you're gigging in one of *those* coffeeshops.

2 XLR/1/4" combo channels, Bluetooth connectivity, and a USB interface round out the features here. It may look retro, but all the modern appointments are there. Oh, and it packs tons of power—100 watts. So, say hello to your first and your last acoustic amplifier.

Reasons to Avoid:

• Some users say the sound is too bassy

7. Best for Versatility - Positive Grid Spark LIVE

SPECS:

• Number of Channels: 4
• Output power: 150W
• Speaker Size: 2 x 6.5" Custom woofer, 2 x 1" Compression Tweeter
• Inputs: 1 x 1/4" (input 1), 1 x 1/4"-XLR Combo (input 2), 2 x 1/4" (input 3/4, stereo L/R)
• Connectivity: USB, Bluetooth, MIDI
• Software: Spark App
• Weight: 26.45 lbs. (27.5 lbs with battery)

I've expounded at length elsewhere on the joys of the Positive Grid Spark app and its endless combinations of amp sims, virtual pedals, and more, but PG's innovations don't end there. They've recently introduced the Spark LIVE, Positive Grid's biggest and most feature-laden amp to date.

Designed with live performance in mind, the Spark LIVE makes for a great portable PA system and acoustic guitar amp that packs a big sound, but doesn't skimp on features for learning and jamming either. Tons of connectivity, including MIDI, Bluetooth, and USB as well as integration with the Spark App make the Positive Grid Spark LIVE a no-brainer for the most versatile acoustic amp out.

4 channels mean you can technically power a full band here, and with two configurations (wide and focus modes), you can even optimize for your environment. Thanks to Positive Grid’s Sonic IQ technology, this thing gets freaking loud—even for a 150W amp, which is pretty dang powerful to begin with. Far from just an acoustic amp, the Spark LIVE is the perfect choice if you're looking for a portable full-band jamming solution.

Reasons to Avoid:

• There are simpler options if you're not a tech person

8. Best Acoustic Preamp - Tonewood Amp 2

SPECS:

• Type: Acoustic Multi-FX
• Analog/Digital: Digital
• EQ: 3-band EQ
• Effects Types: Chorus, Reverb, Delay, Tremolo
• Weight: 0.54 lbs.

Okay, it's not really an amp—more of a preamp/multi-fx processor/generally really cool gadget that you must check out. The Tonewood Amp 2 is a portable effects processor, seemingly (at first) not unlike the Spark GO, that attaches to your acoustic guitar and allows you to toggle effects, save presets and more.

But here's the kicker: you don't need an amp. The Tonewood Amp 2 is like a portable amp that physically vibrates the body of your guitar, imbuing it with whatever tonal effects you've selected. It's actually mind-blowing technology that has to be seen to be believed. Guitarist Mike Dawes, in his demo for Sweetwater, says "it's like making every room in your house sound like the bathroom."

So where the Spark GO is a portable amp that functions as a conventional amp, with a tiny speaker, the Tonewood Amp 2 might be a better choice for those who really like going acoustic mode—but still want to zhuzh up their tone with a little something extra.

App integration makes the Tonewood 2 easily controllable without having to poke around on the back of your guitar, and the variety and customization of effects available is really comprehensive as well.

Plus, not only does the Tonewood Amp 2 effectively turn your guitar into an amp, it functions as a preamp for live use as well—so you can bring your favorite settings that you use at home and pump your signal through the house system.

Reasons to Avoid:

• Not for those in search of a conventional amp

9. Best Features - TC-Helicon Harmony V60

SPECS:

• Number of Channels: 2
• Output Power: 60W
• Speakers: 1 x 8" Dual-concentric Tannoy Speaker, 1 x Tweeter
• Effects: 3-band EQ, Reverb, Echo, Chorus, Harmony, Pitch Correction, Looper
• Weight: 24.6 lbs

Finally, the TC-Helicon Harmony V60 is another premium pick for singer/guitarists who are looking for top-notch signal processing and effects, without compromising on aesthetics.

It features separate voice and guitar channels, with the voice channel providing everything you need to produce a polished, professional live vocal sound, including adaptive EQ, compression, de-essing, pitch correction, and harmonizing.

As a guitar amp. the Harmony V60 shines as well, with a unique speaker arrangement that angles the tweeter at the player for effective onstage monitoring, a built-in tuner, looper, and no shortage of effects.

What's more, there's a footswitch for easy control in a live setting. All this packed into an attractive wood chassis. For the singer/guitarist who is looking for maximum features for live production, the TC Helicon Harmony V60 is a sure bet.

Reasons to Avoid:

• This many features will surely be overkill for some

The Verdict

Hopefully, this list helped narrow your search for the best acoustic guitar amp. To recap, I think the Fishman Loudbox Artist BT has the right mix of features, power, and portability to make it the best overall acoustic amp in its class.

But if you're looking for something a bit more affordable, more stylish, or more portable, there are options for you as well. Many acoustic amps offer more or less the same array of features nowadays, so you can't go wrong to just pick one that's in your budget that you like the look of. Isn't that more or less how we all choose our gear at the end of the day, anyway?
