While playing electric guitar brings an abundance of possibilities with all the effects and the wide palette of sounds that you can make, there’s just something about acoustics that cannot be replaced. That true resonating tone coming directly from the instrument and not any outboard effect makes it so pure.
Of course, acoustic guitarists also want their tone to be amplified. Some might prefer to mic it up – a bit of a delicate process for an acoustic instrument but that brings great results.
Another way to amplify it is via piezo pickups, which is more practical but might not give as full of a tone as a miked up guitar.
Either way, whatever your preference might be, there are some great amps out there specialized for acoustic guitars.
In some way, they are like smaller PA systems designed specifically for acoustic guitars and occasional vocals.
Whether you’re a professional or an amateur player, here we will be taking a closer look into some of the best amplifiers for acoustic guitars that you might want to check out.
We’ll start things off with AS50D by Marshall. This 50-watt amp has two 8-inch speakers and an additional tweeter for high-end tones.
There are two inputs on it, one of which is a standard 1/4-inch instrument jack, and the other one an XLR for microphones. What’s great here is that both of these channels have separate volume, bass, and treble controls.
The amp also features a solid chorus effect circuit integrated into it. You can apply this chorus either on one or both of the channels. As for other features, there’s anti-feedback control, reverb, and even an effects loop.
It’s a fairly simple amp with great tone and some useful features added to it. Most certainly worth the price.

Okay, this is a bit of a smaller one, but we can’t help but mention Yamaha‘s THR5A on a list like this. Its 10 watts might not be much, but the amp can deliver enough power for practice sessions, street performances, and even some smaller gigs.
Just like on Yamaha’s small electric guitar amps from the same series, the tone goes through two 3-inch speakers, which impact the tone in their own way.
The strong point of THR5A comes with different onboard effects and digital microphone models. All this with the capability of powering it via eight AA batteries which give about six hours of playing time on average volume levels.
And not only can you add backing tracks via auxiliary input, but there’s also USB connectivity that turns this amp into a convenient little 2-channel audio interface for home recording. Pretty wild what this amp is capable of, despite having only 10 watts of power.

Roland is a company well-known for their quality products. Their amps are famous for their clear tone that goes well with any kind of additional effects.
While we’re familiar with their Cube series for electrics, there are pieces like the AC-60, also known as the Acoustic Chorus amp. This one bears the power of 60 watts and two 6.5-inch speakers for stereo output.
There is also an onboard multi-effects processor with delay, chorus, and reverb, as well as the additional feedback control.
There are a few more useful features on it like stereo outputs, both for PA and for any recording device. In addition, there’s also a separate subwoofer output. The whole thing is rounded up with footswitch connectivity.
What’s more, the amp also has its own integrated tilt stand that offers some more acoustic positioning options. Overall, it’s a fairly versatile piece that gives some pretty solid and crystal clear tones.

While we mostly remember Vox for their electric guitar stuff, like the legendary AC15 and AC30 amps, they also have a solid acoustic amp like the VX50AG.
Although it’s a bit of a budget option, this thing can offer some serious tones for acoustic guitars. There are, of course, two inputs ñ classic 1/4-inch one for piezo and an XLR for microphones.
There’s also a phantom power feature in case you want to use a particular condenser mic.
Both of the channels have their own separate controls for volume, bass, mid, and treble, and the instrument input also has chorus and reverb effects.
It’s pretty easy to operate, it works well, it sounds great, and it’s fairly cheap. You can’t go wrong with the Vox VX50AG.

AER Compact 60/3
Now here’s a bit more serious amp for those who seek fully professional gear. Although expensive, the price here is definitely justified.
It’s designed to be a fairly simple piece that reproduces the natural tone of your guitar. However, this also means that you’ll need to have a quality high-end acoustic guitar in order to get the full potential out of it.
Although simple, you have some additional features, like the onboard effects, effects loop, and the tuner output.
Generally speaking, the pristine tone reproduction is this amp’s biggest strength. Whatever is the type of acoustic guitar that you have, it will reproduce its tone with all of its distinct features and nuances.
What’s more, the AER Compact 60/3 is pretty light to carry around, something that is pretty impressive for a 60-watt amp.

Boss Acoustic Singer Pro
Another professional-grade acoustic guitar amp, Acoustic Singer Pro by Boss is a powerful little thing featuring 120 watts.
There are two standard channels, one with an instrument input and the other one with a combo line/XLR jack and phantom power. Both of the channels have completely separate controls.
But what’s really exciting is that the amp has looper feature for the instrument channel and the harmonizer effect for the mic input. This means that you can add vocal harmonies and do a few layers of guitar tracks on a loop.
To implement its full potential, there’s also USB connectivity that allows you to use it as an audio interface.
It’s an amp of great quality that’s really fun to use. Is there anything more that you need?

Here are some additional options when it comes to gigging with an acoustic guitar, if you need it to be louder.
We spoke with Tom Anderson of Anderson Guitarworks, in Newbury Park, California, and his best bet isn’t even an amp!
Tom says, “I run from an LR Baggs Session DI into the house PA system.” What kind of house PA, we asked. “Whatever the venue has, most are pro installations with good wedges for monitoring.”
Here’s a look at the LR Baggs Session DI…
According to LR Baggs’ website, “Inspired by the LR Baggs Handcrafted Video Sessions and our experience in some of Nashville’s great studios, the Session Acoustic DI brings our signature studio sound to your live rig. The Session DI enhances your acoustic pickup and imparts the rich sonic character that you’d expect from an experienced audio engineer using some of the world’s finest studio gear. We’ve captured this studio magic and put it into a compact, easy-to-use DI that will transform your live sound.”
