Best Acoustic Guitar Amps of 2021

best acoustic guitar amps

Acoustic guitarists have options with how they amplify their sound. In many cases, the acoustic guitar signal will be sent into a D.I. box and then out to the house sound system. While this method is simple and tried-and-true, you might want to explore the different sounds that acoustic guitar amps provide.

With an acoustic guitar amp, you can expand your sound by adding effects and microphone modeling, as well as being able to amplify your direct signal, a microphone, or even vocals. Whether you’re busking on the street, doing a set at the coffeeshop around the corner, or wanting to get adventurous in the studio here are some of the best acoustic guitar amps available today.

How are Acoustic Amps Different Than Electric Guitar Amps?

Unlike electric guitar amps, acoustic amps are designed to fully replicate the sound of the guitar. This means they provide a clean, transparent platform for you to build on and generally don’t introduce any extra “mojo”. While it’s entirely possible to get a great electric sound by using a nice amp with a guitar made from a countertop, acoustic guitar amps respond very differently in their relationship with the guitar.

Feedback is the worst enemy of an acoustic guitarist, and if you add in an amplifier, things can get out of control quickly. Luckily, many acoustic amps come with ways to combat feedback. These include phase, filtering, or altogether noise reduction. These features go a long in keeping things under control but remember proper sound techniques are still critical.

Why Use an Acoustic Guitar Amp?

So, what’s the advantage to using an acoustic amp? For starters, it puts control of the sound more in the hands of the player. They are great for smaller gigs where there might be an underpowered sound system – if there is one at all. And if there’s not, you can run a vocal into the amp. They are also very convenient and portable for smaller gigs. Beyond that, they really do provide a sound all their own – which you may or may not like.

Effects on Deck 

Pedals are becoming increasingly popular in the acoustic world, and many acoustic amps now come with onboard effects – or at the very least reverb. These let you expand your tonal options without having to lug around additional gear.

Best For Recording: Yamaha THR5A

Acoustic modeling isn’t very common when it comes to acoustic amps, which makes this entry from Yamaha all the more unique. It provides a clean modeling amp platform and includes a host of condenser and dynamic mic simulations. Also included is a host of effects and a tuner. It’s compact, easy to dial in, and can really push the envelope when it comes to creating new acoustic sounds. It comes with its own editing software, but unfortunately some of the effects are only accessible through it.
