I first grabbed the guitar in 2009. I started this website in January 2020 because I couldn’t do window installation anymore due to my health problems. I love guitars and have played dozens and dozens of different guitars through different amps and pedals over the years, and also, building a website interested me, so I decided to just go for it! I got lucky and managed to get awesome people to help me with my website.

I also got lucky because I have you visiting my website right now. Thank you. I do all this for you guys. If you have any recommendations, tips, or feedback, just leave a comment, I would love to chat with you. I have also been fortunate to produce content for several large guitar websites, such as SongsterrMusicnotesGuitarGuitar, and Ultimate Guitar.

I spend my spare time exercising and hanging out with my wife and crazy dog (I guess that went the right way…).

Every one of these acoustic amps is here based on extensive research and decades of combined guitar experience of me (Tommy) and Teemu.

Speaker Size6” woofer with 1” tweeter
Battery PoweredNo
Weight 21 lbs. or 9.5 kg
Modeling?No
XLR Input?Yes
Bluetooth CompatibleYes
EQ3 band EQ
EffectsReverb

Sound

If you’re not concerned about price and want the best-sounding small guitar amp for acoustic out there, the Fishman Loudbox Mini Bluetooth could be the amp for you.

It boasts 60 watts of solid-state power from a 6-inch woofer and a 1-inch tweeter. Together, these speakers blend your acoustic frequencies in a way that kicks while still being smooth.

The Loudbox Mini features reverb, chorus, and EQ, so you can adjust your levels however you please.

Hear how this amp sounds:

Features

Among its many standout features is that the microphone channel has its own set of EQ and effects controls.

With this, dialing in your vocal mic to sit perfectly on top of your acoustic channel is easy.

The Loudbox also has a feedback-resisting Phase switch that you can use to eliminate the pesky noise you’ll be encountering at the louder volumes.

Usability

You can connect your phone or PC via Bluetooth or the AUX to add any accompaniment you want. Afterward, you can use the XLR DI jack to sync up with your home studio software and record your latest licks.

It has many neat features, but none of them are complicated. So, if you’re a beginner with a big budget for your first amp, this isn’t an amp that would be out of your league.

To top it all off, this comes in a tiny package. The Fishman Loudbox Bluetooth Mini stands only 12” high and weighs 21 pounds. Though it’s not battery-powered, it’s portable enough to take anywhere you can plug in.

Summary

Pros

  • Great balanced acoustic tone driven by 60 watts of power
  • EQ on both instrument and microphone channels
  • Big voice in a small package
  • Bluetooth, XLR DI, and AUX connectivity

Cons

  • More expensive than its small amp competitors

All things considered, the Fishman Loudbox Bluetooth Mini is the most versatile, most powerful, and most professional of the amplifiers featured in this article. It provides excellent tones from flatpicking to strumming to acoustic fingerstyle.

It costs quite a lot for a small guitar amp, but its big, clear voice and connection capabilities give it the value of much larger amps at a similar price point.

Best Around $100 & Best for Beginner – Fender Acoustasonic 15

Specs

AmplifierFender Acoustasonic 15
Wattage15 watts
Speaker Size6” speaker
Battery PoweredNo
Weight 10.5 lbs. or 4.75 kg
Modeling?No
XLR Input?Yes
Bluetooth CompatibleNo
EQ3 band EQ
EffectsChorus

Sound

The Fender Acoustasonic 15 is similar to the Donner DGA-1 in many ways, but one unique feature really sets it apart.

Both are rated at 15 watts of output and have closed backs to kick up the bass and mid-punchiness. They both have XLR mic inputs, but the Acoustasonic has an extra element in its speaker design that makes this mic jack more usable.

This is a “whizzer cone,” a small cone placed on the center of the speaker’s 6-inch cone. It drives up the higher frequencies. Doing this helps the mic input cut through the mix of the guitar.

However, if your guitar is treble-heavy in the first place, the amp might sound too sharp in the high end.

Hear how this amp sounds:

Features

The Fender Acoustasonic 15 has a chorus controlled all with one knob. At the far left position, you’ll have no chorus at all. The more clockwise you crank it, the more presence and speed the chorus will have.

Another great feature is the 3-band EQ. You can tame those glassy highs or bring up or down whatever frequencies you need to change. Again, this only works for the instrument channel, so your mic must be EQed earlier in your signal chain.

Usability

This is another great amp for beginners with straightforward controls and basically nothing confusing in its usage. By just plugging and playing, you can let both your guitar and voice be heard. On the other hand, you can plug in headphones to keep your jams on the quiet end.

At hardly over a foot in length and width and a little 10 pounds in weight, the travel-friendliness of the Acoustasonic makes it an excellent amp for guitar lessons.

Summary

Pros

  • Addition of “whizzer cone” on speaker adds depth to sound
  • Very shimmery chorus effect
  • Small for portability but loud enough to fill a room
  • Affordable

Cons

  • The tone is overall treble-heavy

Fender knows tone, and their combination of the whizzer cone in the Acoustasonic 15 sets this amp up to be one of the best acoustic amplifiers.

The Fender Acoustasonic 15 is my favorite entry-level acoustic guitar amp with enough juice, tone, and chorus to keep beginner guitarists playing for a long time.

Best Modeling – Positive Grid Spark Mini

Speaker SizeTwo, 2” speakers
Battery PoweredYes
Weight 3.3 lbs. or 1.5 kg

Bluetooth CompatibleYes
EQYes
Effects33 amp models + 43 effects

Sound

The Positive Grid Spark Mini is a tiny powerhouse of tone. This little lithium-ion battery-powered buddy dishes out an impressive sound for such a compact size.

Two 2” speakers push out 10 watts of power. While these speakers are quite small compared to other “small” amps, don’t be fooled. This lightweight amp has almost everything you could imagine in a tiny amplifier.

The amp offers extremely versatile sound and the Spark app you can download to your phone plays a big role in this. It has tons of different pedals, amplifiers, 2 done for you acoustic guitar signal chins that you can adjust, plus much more. The app also features backing tracks and even an AI drummer that adjusts to your playing.

Also, Spark works as acoustic, electric, and bass guitar amplifier. So even if you are a multi-instrumentalist, it’s a great option.

Features

The Positive Grid Spark Mini has so many excellent features that it is difficult to know where to begin. Perhaps the most exciting feature is the Spark Mini’s companion app, which gives you access to 33 different amp models and 45 effects. That is quite an impressive number, no matter the size of your amp!

If quantity was the sole determiner, then the Spark Mini would be a hands-down choice. However, the quality of these sounds is top-notch for a product in this price range.

Additionally, the Spark Mini features an 8-hour battery life, a USB line to plug into your DAW and record, and the option to create a custom grille for your amp – super cool!

Usability

The Spark Mini is built with the beginner to intermediate guitarist in mind and designed to give the user as many creative tools as possible to inspire their guitar journey. If I was a beginner or intermediate player, I would be extremely excited about this guitar amp.

The companion app also includes instructional material and functions as a Bluetooth speaker, so you can jam to your favorite tunes anytime.

The amp is extremely portable, weighing only 1.5 kg and small enough to fit in your backpack or tote bag.

Summary

Pros

  • Small, portable, and versatile.
  • Huge range of tones, amps, and effects to learn with.
  • USB out for recording.
  • Backing tracks & smart jam & metronome available in the app
  • Long battery life.

Cons

  • Acoustic guitarists might not be interested in the heavily distorted or overdriven amp and effect models.
  • The amp might distort too much at higher volumes.
  • Some Bluetooth connection issues can happen

Best for Street Performers – Roland CUBE-10GX

Speaker Size8” speaker
Battery PoweredNo
Weight 10.3 lbs. or 4.7 kg

EffectsReverb, Chorus, & Delay

Sound

The Roland CUBE series was one of the original small guitar amps and remains a strong choice, especially for street performers. These amps can take a beating, surviving the concrete and potential mishaps and conditions of busking.

Like some of our other choices, the Roland CUBE-10GX pushes out 10 watts of power, this time through an 8” speaker housed behind a polished metal grille. A sturdy, closed-back cabinet is finished off with heavy-duty rubber around all the corners, just in case your amp takes a little tumble.

The Roland CUBE-10GX is relatively straightforward, sound-wise. The CUBE offers three amp types featuring Roland’s legendary COSM modeling technology: Clean, Crunch, and Lead. It also includes a 3-band EQ and reverb, chorus, and delay control.

Hear how this amp sounds:

Features

While the Roland CUBE is not a standout for its incredible features, it is a solid, dependable choice for a street performer. I have used the Roland CUBE series amps as a busker and have seen them in cities worldwide on sidewalks, parks, and marketplaces.

The amp has a ¼” auxiliary output, so you can plug it into larger speakers. It also includes a dedicated headphone jack for quiet practice.

Usability

The Roland CUBE-10GX is highly usable as a small amp for acoustic guitarists. The solid-state design, simple amp-type models, and basic EQ plus effects will give you more than enough options to shape a suitable tone for busking or other street performances. 

The amp is lightweight, rugged, and built to last.

Summary

Pros

  • Compact, simple design.
  • Lightweight and sturdy.
  • Strong reputation.

Cons

  • No battery power.
  • No XLR/mic input for vocals or other instruments.

The Roland CUBE-10GX is a solid choice for a small acoustic amp for a street performer. With simple controls and a solid tone backed up by a long production history, these amps are a staple of street performers worldwide.


Best for Recording – Yamaha THR5 Mini Acoustic Guitar Amplifier

Specs

AmplifierYamaha THR5A
Wattage10 watts
Speaker SizeTwo, 3” speakers
Battery PoweredYes
Weight 
Modeling?Yes
XLR Input?No
Bluetooth CompatibleNo
EQ1 band EQ
EffectsModulation, Delay, & Reverb

Sound

If we look at the shape and color of the Yamaha THR5A’s sound, it’s a really impressive mini acoustic guitar amp.

Out of the box, this amp comes packed with 5 mic presets ranging from a standard condenser mic to the sound of a clean electric guitar. While most presets give you clean tones with varying EQ levels, the electric guitar EG CLN setting has a gritty bite.

These mic presets can then be modded with various effects, so this is a little amp with a lot of versatility. Every tone is excellent, thanks to Yamaha’s Virtual Circuitry Modeling technology.

It gets even better knowing that you can use free downloadable THR Editor software to change the specific settings of each control, giving you total power over the flavor of your tonal presets.

Hear how this amp sounds:

Features

Now, in line with the THR5’s small build, its low power rating is almost woeful. 

This amp can only sing with 10 watts, which is not much. It’s a great amp for practicing alone or recording at home, but there’s no way it could keep up with a drummer.

And for gigs? Sorry, but 10 watts won’t drown out even a tame bar’s chatter.

More volume would be nice, but it would also increase the size, weight, and price of this compact, relatively affordable amp. And, considering it can run on a handful of AA batteries, 10 watts is impressive.

Usability

So, knowing its limitations, it’s safe to say that this amp is best used for songwriting, rehearsing, and recording. It actually comes with a free copy of the recording software Cubase AI, so it’s all you need to get your guitar on the reels.

Editing your presets through the THR software might be more challenging for the less tech-savvy, but setting your preferences through the preloaded mic models and effects couldn’t be easier.

Check our picks for the best Yamaha acoustic guitars here.

Summary

Pros

  • Choice of battery or AC power for playing at home or on the go.
  • Editable preset effects and microphone models.
  • Comes with recording software.

Cons

  • 10 watts of power isn’t loud enough for performances

I’d recommend this amp for intermediate to advanced acoustic guitarists who want to get more serious about their home studios.

It has a beautiful range of tones suitable for any acoustic genre, and if it doesn’t have what you’re after, chances are you can edit it to be correct.

It’s not cheap, but the tonal quality is worth it if you don’t need a lot of volume.

HOW WE CHOSE THESE Amplifiers

  1. We decided which guitar amplifiers to recommend by using our own experience, doing extensive research, visiting music stores, and asking help from our musician friends
  2. After we had chosen the best amps to recommend we looked for a good way to test the gear. This means either renting it, buying it, testing it in a music store, or visiting a friend who owns it. This time, our main testing methods were receiving some amplifiers from manufacturers for testing (Positive Grid) and testing some amps in music stores.
  3. Even after this, we’ll still do another round of extensive research to make sure that this specific product is in fact, a real cream-of-the-crop candidate.
  4. Then we wrote this in-depth but easily digestible review about these amps. We kept in mind who would be playing them (most likely) such as bluegrass players, blues players, beginners, advanced players, etc. 

Most guitar amplifiers we recommend are run through tests like these:

  • We go through every possible amplifier setting
  • We inspect overall build quality and portability
  • We test the amp with single coil and humbucker pickups
  • We inspect and rate the overall usability of the amp
  • We measure and weigh the amplifier.
  • We test different settings and rate the versatility of the amplifier
