Practicing? Sometimes you need just a little more umph. Playing a concert? Then you’ll definitely need more volume.

These are the reasons we have acoustic guitar amps. But how can you know which one to choose?

We had the same question, so we put together this list of the top seven amps that work best with acoustic guitars.

Marshall AS50D

The Marshall AS50D is small yet powerful enough for smaller or mid-sized performances. It has two channels, so you can plug in both your acoustic guitar and a vocal mic. That means you won’t need to carry around a bulky PA system to every gig. Although if you’re playing a larger gig, you can feed your signal to the house mixer using the line out and DI.

And what would a concert be without a little chorus and reverb effects, both of which you can get on this amp. Almost every vocal needs a touch of reverb, and the chorus effect can sound nice on your guitar.

We should note, some customers have complained about the low-quality materials used to build the amp, saying the knobs have broken off.

Specifications and features:
  • 50W of power
  • Two 8-inch tweeter speakers
  • Two instrument inputs, one XLR input, and one RCA Stereo input
  • Effects: Chorus and Reverb
  • EQ: Ch. 1: 2-band, Ch. 2: 3-band
  • Feedback Control included
  • Effects Loop included
  • Footswitch I/O included
  • Weight: 35.27 lbs.

Fender Acoustasonic 150

The highlight of this amp is the combination of its lightweight body and its clear and resonant sound. It has a Voicing control that lets you emulate different acoustic sounds, like parlor, dreadnought, or jumbo.

With this little amp, you have a quarter-inch instrument channel and a Phantom-powered XLR/quarter-inch input, meaning you can plug in your acoustic guitar with a mic or another instrument. These channels each have reverb, delay, chorus, and vibraphone, to name a few.

Several users have reported this amp actually has a weak output and sometimes has sound quality issues. This is an amp you may want to test out before you buy.

Specifications and features:
  • 150W of power
  • Two 8-inch neodymium drivers
  • Two channels: quarter-inch instrument input and an XLR/quarter-inch input

Behringer Ultracoustic AT108

Don’t let this amp fool you with its cheap price. It delivers an upfront sound, thanks to the Virtual Tube Circuitry, and plenty of options.

It has an instrument and XLR input for dynamic mics, making it a the perfect amp for small gigs in coffee shops, houses, or sidewalks. Plus, you get a CD input for practicing along with any song, and you get a headphone jack for private rehearsal. Then you can use the 3-band EQ to shape the precise tone you want.

Specifications and features:
  • Total Power: 15W

AER Compact 60

Although compact, it packs a punch. If you’re a singer-songwriter and need something that will loudly amplify your true sound. It’s easy to take with you, so it’ll work well in any coffee shop gig, even the one across town.

With the two channels -- quarter-inch instrument input and an XLR/instrument input -- you can do a solo set with just your voice and a guitar, or you can team up with a friend for an dual-instrumental set.

This one is a bit pricier, And overall, it’s ranked in the 4- to 5-star rang. But some people who have used it say the effects available may not be sufficient.

Specifications and features:
  • 60W of power
  • Quarter-inch input and XLR/quarter-inch input
  • One 8-inch speaker
  • Two channels with 3-band EQ
  • Two reverb options, Delay, and Chorus

Fishman Loudbox Artist

With an impressive 120 watts of power, you won’t need to worry if this amp has what it takes to project. Although somewhat small, this amp can work for most mid-sized concerts.

What’s nice about this amp is that it has two phantom-power-required XLR/quarter-inch inputs, so you can do any combination of instrument and voice. Plus, it has an aux stereo input and an effects loop option for each channel.

Then you can mix all of these channels together with a 3-band EQ, slap on some Reverb, Chorus, Delay, and/or any of the other effects available and you’ll be in business.

One downside is that the leather upholstery tends to scratch and peel off easily, so watch out for that.

Specifications and features:
  • Two XLR/quarter-inch inputs
  • Three-band EQ and feedback control
  • Aux stereo input
  • Effects (independant for each channel): Reverb, Chorus, Flanger, Delay, Echo, and Slap Echo

Fishman Loudbox Mini

If you need a portable amp for practicing or something to act as a mini PA, the Fishman Loudbox Mini is a great option. With 60 watts of power, you’ll have the power to project your sound, and at just 20 lbs., you’ll have no trouble taking it from gig to gig.

For practice, you can hook up your smartphone or MP3 player to play along with your favorite song. And for gigs, you can use the quarter-inch instrument channel alongside the XLR/quarter-inch input to present a nice voice-guitar combo. And thanks to the XLR DI output, you can easily monitor your mix onstage and send it to the mixing board without using a DI box.

Some guitarists say it wears out and breaks after a short period of time, so you may want to buy this amp new and with a warranty.
