Acoustic Guitar Amps

Professional musicians have long favored the Compact 60/4 by AER because of its outstanding efficiency, which includes crystal-clear clarity without interfering with the sound of your acoustic guitar. The only difference is that its dashboard delay is exchanged with the chorus/reverb mix from the setting 99 in a classic Alesis MIDIVerb, so it costs around $30 more than the MkIV.

We might be intrigued, but we have a lot of other features to look into here. The Compact 60/4 is extremely useful. Its boxy birch-ply chamber is suitable for both studio and a stage, and it is lightweight and compact enough to carry on public transportation.

Second, it has several player-friendly options available, all of which are easy to use. For the symptoms, there are four options. This amplifier is somewhat similar to the famous MkIII. The Colour transition will help accentuate playing finger style by cutting the low-mids as well as boosting the highs, which can be fine-tuned with the EQ.

Transparency continues to be a major feature making the Compact 60/4 completely neutral. It also includes an auxiliary input that can adjust levels, a FX switch that positions any direct signal during setting onboard effects.


  • It has its transparent efficiency at the highest caliber
  • Small, convenient, and efficient
  • The construction quality is incredible
  • The sound effects are fantastic


  • It's not cheap

2. BOSS Live LT

Boss' Live LT Acoustic series uses a bi-amp system to provide an easy amp alternative for musicians, and its outstanding style, sound, and reasonable price makes it a highly appealing choice for just about any electro-acoustic musician.

This amplifier has a smaller frame, and although it lacks a vocal harmonizer, an onboard looper, and a dual DI, it still has a number of characteristics that make it suitable for live use. It contains a vocal enhancer where a single button boosts the voice as well as pause, echo, and synth.

A series of acoustic responds, each from a touch of the button, can also be used to quickly adjust your acoustic sound. An anti-feedback power, chorus, reverb and delay are all available on its guitar channel, and all have their respective 3-band EQs. There's also a USB connection for video, as well as an aux-in having a convenient control system for mixing in additional audio.


  • It is a more compact and cost-effective edition
  • Because of its set of features, it's perfect for stage concerts
  • The amplifiers tones are fantastic


  • Upgraded features of Live models or Pro are required

3. Blackstar Sonnet

Acoustic Guitar Amps

The Sonnet 120 is part of Blackstar's Sonnet range of acoustic amplifiers, which was developed in partnership with the British songwriter and singer Jon Gomm. If you're passionate about your music and would like to take the acoustic electric tone to another level, but you're on a budget, the Blackstar Sonnet 120 could be the answer.

The construction efficiency is outstanding. The inbuilt tilt rack is very useful on stage, and the option to install the amp on something like a regular PA stand with a SA-2 adaptor is even more useful. The Sonnet has a naturalistic tone and it has a lot of tone-shaping options. A shape controller can be used to swap between a plain EQ and a bass or treble enhanced mode.

The Sonnet offers a plenty of choices for dialing in a sound that fits with other players thanks to its form power, high-pass filter, including a brilliant sound controls system. Aside from that, there are four outstanding optical reverbs, some footswitch to power them as well as Bluetooth and MP3 input to jam to a music track.

4. Fishman Loudbox Mini

Fisherman chose to keep things simple with its Loudbox Mini model. There are just a few inputs and outputs: a regular mix DI output, guitar and mic inputs, as well as an auxiliary source for playing backing tracks or MP3.

And, thanks to its Bluetooth connectivity feature, you may not even require the latter. The Loudbox Mini has been designed to be an easily portable, simple to use amp for street musicians who are passionate about their craft.

Simply plug it in and let it charge for 12 hours at a lower volume and 4 hours at full volume. If you have to play for long, it would be quite a package. However, you may want to because this amp sounds fantastic.

On its guitar channel, it has a built-in reverb and chorus, as well as an EQ of 3-band for fine-tuning when you go to where you have to perform. It is quite loud enough for a crowded street and compact that can be carried on public transportation.


  • Both channels have their own channels

  • It would be great to have a looper

5. Fender Acoustic SFX II

Acoustic Guitar Amps

The SFX ll seems to be unique among acoustic guitar amplifiers. With a maple-ply container, it seems to have a retro-minimalism that evokes Danish modernism. It would look great next to some Klint chairs at home, or in a coffee shop, a club, or anywhere else you want to play it.

The Stereo Field Expansion technology, which gives the SFX its name, sets apart from most other acoustic amplifiers with two channels. The SFX contains two similar channels, each with an instrument jack of 1x4 inches and an XLR microphone source. It also has an EQ of three bands, an effect level, reverb, and phase and volume control for feedback.

The effects can be regulated by a core panel which provides two forms of delay with tempo: one having a retro echo effect and the other going for a little faster pace with frequent repeats


  • SFX gives your sound a delicate ambient depth
  • The XLR mic comes with ground lift switch
  • Has multiple beautiful effects


  • It’s a big large and heavy weighted, making it inconvenient to carry it around

It has a two-channel system with separate treble and bass controls for the individual channels, as well as phase and anti-feedback wave controls to ensure an uninterrupted performance.

There's also a specific line out if you need to go straight to PA or right to your desk to record. Marshall allows you to choose between channels to add the chorus to, as well as control the depth and tempo. However, it has an effects switch on board if you ever need to hook up a wait or something.

For the ones who would like having few sound effects on their acoustic guitar, the AS50D will be the best choice for acoustic guitar amps. The reverb control allows you to switch the reverb or the direction of the simultaneous effects loop on each channel.


  • Reverb and Chorus are built-in

  • Suitable for concerts as well as street performances
  • Has an excellent regulation of feedback

  • It's not as lightweight as some of its competitors

Info Section

If you're new to guitar amplifiers, the first thing you'll notice is that their operation differs from that of an electric guitar amplifier. The purpose of a guitar amplifier is to faithfully amplify the sound of your acoustic guitar without any distortion, interference, or unnecessary vibration that electro-acoustic can produce.

Where an excellent electric guitar amplifier will make a block of fuel wood sound usable, an acoustic guitar amp must make do with what it has.


Many acoustic guitar amps have onboard features, such as reverb, which gives the sound some depth and lightens up a dark space, as well as pause and chorus. A sound loop feature may be necessary if you're a part of the next generation of acoustic musicians who are shepherding an ever-expanding pedal board.


Most decent electric preamps including acoustic guitar amplifiers have some kind of feedback prevention, like a step, notch filter, or sweep. Feedback is the bane of an acoustic player's existence, and it can hit at any time. It's not always the room that's the issue; however, identifying the problematic frequency and eliminating it will improve the overall efficiency.

Amps with notch filter as well as a resonance frequency control, such as the Fishman Loudbox Mini will give you complete control. Others would have mode switches, which are on and off switches that shut off any of the lower frequency that can create problems.

Battery Power, Outputs and Portability

There are some other practical considerations which an acoustic guitarist should keep in mind before purchasing a guitar amplifier. You'll need to get an amplifier that is battery-powered if you plan on performing on the street. In this guide, there are two options for you: the Fishman Loudbox Mini, which is a wall-charged amp, and the Roland AC-33, which uses a set of rechargeable batteries.

It's also possible that the right acoustic guitar amp is a matter of outputs. You'll require a XLR DI outlet or a line out if you're aiming for a recording amplifier or want to transmit a signal through PA speakers. Most of the amps can have a range of options here, including ground raise to eliminate hum and the ability to choose output channels in certain cases.

To Conclude

When it comes to musical instruments, every artist will have his/her own collection of tastes. The larger the audience you'll be performing in front of, more important it is to consider which amp will be best and more appropriate for you. This guide should have given you some useful insights into the best acoustic guitar amps out on the market.
