An Acoustic Guitar Amps Review: A Look at the Best Acoustic Guitar Amps

First becoming popular in the 1990s, acoustic amps are little PA systems in a box that can handle your guitar signal very well, have an additional input for a vocal microphone, and can reinforce a small-room or coffeehouse solo gig with ease.

They often feature onboard effects, as well.

This combination of features allows solo giggers to travel lighter than ever before.  

Even for those not playing solo, a good acoustic amp makes for a much better stage monitor than the house sound system does, lets you shape and control your tone, and most likely has a balanced XLR output for patching you into the aforementioned house system in a much better way than straight out of your guitar.

Our discussion today will be about a handful of acoustic amps on the market today that might be just the thing you’re looking for to make your live sound better, stronger, and louder.

Start thinking about what features you need because it’s time to dig some amps!

Acoustic guitar amplifiers have become an important part of the gear collections of many modern acoustic players.

We all know the history and reputation of Fender's legendary electric guitar amps, but the company has also become known in the modern day for its popular acoustic guitar amps.

All of this magic come through one 8" full-range Whizzer cone speaker.

The Acoustic 100 also features a USB Out for connecting to a computer, an XLR Out for stage use, and a Headphone Out.

You even get an Auxilliary Input.

The 100 has the ability to operate on any voltage available, so global tours just became a little easier to endure for Fender users.

100 watts on tap is a lot of power and that ups the Acoustic 100’s versatility a great deal.

It packs plenty of juice, enough that it will work with your band just as well as it does on your solo shows.

A footswitch is available that will let you control the depth of the effects, access a built-in tuner, and gives you a Tap Tempo function.

The Fender Acoustic 100 is a good-looking, great-sounding and affordable little amp that will add a lot of tone and capabilities to your acoustic/electric rig.

Could it be your new best friend? Most definitely.

You can't have an acoustic guitar amps review without actually hearing the amp.

Yamaha’s THR line of lunchbox-sized amps has become very popular with the world’s guitarists for its tone, portability, and versatility.

The THR5 Mini makes sure all of you acoustic folks out there get an invite to the THR party and delivers super tone is a tiny package.

Unlike most amps, all THR amplifiers are designed with offstage playing, not concertizing, in mind.

They also function very nicely as direct recording interfaces for recording and work with practically any DAW currently available.

The THR5 Mini is so small that you’ll think there’s a speaker cabinet that goes along with it but it is entirely self-contained, employing a pair of 3” internal speakers.

The first question asked about an amp this small is “how loud is it?” and rightly so.

The answer is that the THR5 Mini is plenty loud for playing in a home setting or maybe a very small coffeehouse.

Yamaha calls it "the perfect amp for everywhere you play that isn't on-stage," and that's exactly what it is.

As you might expect, the Mini doesn’t offer a second channel for a vocal mic; it just isn’t meant for that type of use.

What it’s meant for is giving you a way to get a plugged-in feeling at home without setting up your stage gear and to be your new best friend when it’s time to record.

Cubase AI Production Software and Yamaha’s own editing software is included and downloadable to help save sounds and move the recording process along.

Condenser and dynamic microphone models are included to enhance your natural acoustic sound.

Delay, Reverb, Chorus, and Compression are available but on multi-function controls that take a bit of practice to master.

It will make your practice experience a whole lot more fun and let you record amazing acoustic sounds with little effort.

The Amosic is a versatile little box that will work with electric guitar, acoustic guitar, bass and vocals.

It’s hyper-portable and hyper-affordable, attributes that will certainly appeal to the hardcore street pickers out there.

Anything too big or expensive isn’t a good choice for sidewalk busking, as that sort of work is tough on gear.

Small though it may be, the Amosic is loaded with practical features.

It has an 8” speaker and a 1.5” tweeter for great full-range sound, Bluetooth 3.0 connectivity, the ability to record your performances to a U Disk, MP3 playback and a bracket that lets you mount the amp to a speaker stand.

It has two inputs, one of which will take your vocal mic, and simple layout of controls that let you take control of your sounds.

The dedicated Instrument Channel lacks any sort of EQ adjustment, but Bass and Treble controls exist over on the Vocal Channel.

Reverb and Delay are available on both.

The Vocal Channel also has a mini-plug Auxiliary Input for connecting all your playback devices.

The best part of the Amosic is the powerful Class D amplifier section and 3000mA high-rate battery.

This combination gives you eight to 12 hours of battery life after a single charge, and that will keep your music going all day long.

You can even put your guitar away and use it as a karoake machine with your friends.

Amosic may be a brand unfamiliar to many guitarists, but the company has a perfect product here for the street musician set.

Acoustic Amp vs Electric Amp

Amps made for acoustic guitar have almost nothing in common with amps made for electric guitar.

Each is built from the ground up using differing design philosophies that make them polar opposites of each other in terms of the jobs they’re meant to do.

An acoustic guitar amp is, for all intents and purposes, a tiny PA system in a single box.

It’s powered by solid state technology rather than vacuum tubes, just like the big PA systems in the venues you play, and is intended to accurately reproduce full-range signals. 

This is why a good acoustic amp is able to handle guitar, vocal, and break music chores with ease.

Most acoustic amps are outfitted with a combination of small speakers and tweeters to allow them to sound good with almost anything running through them.

The idea is to provide natural-sounding and distortion-free performance for an acoustic instrument and a single vocal, adding only basic effects like Reverb and Delay.

Think of an acoustic amp as a box mixer for one person, and you'll start to get the picture.

In larger playing situations, an acoustic amp functions as a stage monitor for your instrument that gives you much better sound than floor monitors can and as your direct box that connects you with the house PA via a dedicated XLR Output.

This feature is usually found on the back panel, so be sure to look for it.

Floor monitors are not always kind to the tone of your guitar, and an acoustic amp will make playing onstage with a band sound a heck of a lot better to you.

Plus, it places your amplified sound behind you which, if you also play electric guitar, is where you’re accustomed to having it.

It’s a big plus to be able to turn your head a bit and get your ear into a direct line with your sound, especially when playing with a drummer or in other loud situations.

What’s also cool about acoustic amps is that they work well with instruments other than guitar.

If you play additional acoustic instruments such as mandolin, banjo, or fiddle, a quality acoustic amp will make them all sound great.

Sounds really versatile, right?

An electric guitar amp is the exact opposite.

It’s not a Swiss Army Knife-type device intended to handle multiple tasks.

An electric amp has only one purpose in this world: to make electric players sound amazing.

That’s it.

Nothing more.

It’s another hyper-niche device that won’t handle your vocal mic, mando, or flattop, at least not very well.

Electric amps can be either tube-powered or solid state, but tubes are preferred by most guitarists.

Unlike an acoustic amp, an electric amp isn’t intended to be neutral or natural-sounding.

It’s expected to have its own character, which it adds to the sound of your guitar.

It’s designed to color your tone.

There are pretty much only three basic flavors of electric amps, those being Fender, Marshall, and Vox.

Every amp being sold today takes its DNA from one or more of those sources of inspiration.

An easy way to understand this is to listen to some of each brand’s best-known users.

For some of the best Fender amp tones ever put to tape, check out the first Stevie Ray Vaughan album Texas Flood.

For Marshall sounds, nothing can beat the first two Van Halen records.

Eddie can’t even get that tone anymore.

The Beatles and Queen are two of the most famous Vox amp bands, and their recordings will give you an idea of the ideal Vox sounds.

Electric amps can be one-box affairs, called combos, or have separate head and speaker cabinets, which are known as stacks.

The most common speakers used in electric amps are 12” drivers and can be used one, two, or four at a time, depending on user preference and the size of the amp in

question.

Ten-inch speakers are also used but hardly ever alone.

Most of the time, you’ll find them in pairs or quads.

How To Choose A Guitar Amp

Picking out a guitar amp is all about choosing the right tool for the job at hand.

Electric, acoustic and bass guitars each have their own needs, and there's never been an amp made that excels with all three.

Accordingly, amps come in many different sizes intended for different uses that range from practicing in the home to playing club gigs to rocking stadium shows.

It’s quite common for working guitarists to have small, medium and large amps in their gear lockers in order to best match each of their gigs.

When considering a new amp, try to determine the type of sound and size of gig you most frequently play and head in that direction.

Find out what players you enjoy employ and use that info as guidance, too.

The absolute best way to shop amps is actually to play through them using your own guitar.

No amount of reading, talking, or watching demo videos on YouTube will tell you as much as a few minutes plugged into an amp you’re thinking about bringing home.

Experience is always the best teacher, so plan on packing up your ax and going out and getting some.

Use the same guitar to try all the amps on your short list, and you'll get a much better idea of their individual flavors.

Pay attention not only to tone but also to how an amp responds to your touch and playing technique.

Some feel like driving a race car while others have more mild manners.

Only you can decide what features, character and tone is right for you, so research and play through as many amps as you can and see what feels right.

The best scenario here is to aim to assemble a collection of amps of varying types for varying types of gigs and sessions.

You'll have much better luck with that approach than attempting to find a single amp that does everything, and you'll also have a bunch of amps, which is way more fun than just owning one.

You really do need to evaluate several choices before making such an important purchase.
