AER Compact 60 has been on the very edge of acoustic amplification for years. The latest version of this awesome box is out and it packs a lot of heat. Right off the bat, you get two individual channels, each with their own EQ clusters.
With that said, Channel 1 is a dedicated instrument channel while Channel 2 can be used for both vocals as well as guitars. The best thing about Compact 60 is its transparency.
This amp was designed to accurately reproduce the natural tone of your acoustic guitar, which is something it does extremely well. With 60 Watts of available power, you are bound to get more than enough volume even in smaller and medium sized venues.

Fishman's long history of making great acoustic guitar preamps has given them a very distinctive insight into the needs of professional acoustic guitar players. They have used all that experience to make some of the most balanced acoustic guitar amps on the market.
Fishman Loudbox Artist PRO-LBX-600 is a midsized amp that packs 120 Watts of bi-amped power. Featuring two separate channels, this box gives you a great guitar tone as well as microphone output. The outstanding core performance isn't the full extent of its capabilities.
There are also numerous effects and a rather decent expansion suite that allows you to hook it up directly to a mixer. Bang for the buck, this amp dominates its segment of the market.
[usrlist "Controls:4.9" "Features:4.7" "Performance:4.9" "Value:4.7" avg='false' max='5' ]
Fender's Acoustic SFX series offer a great bang for the buck to anyone looking to get optimal acoustic tone reproduction. The amp comes with a large number of transducers, including an 8-inch woofer, a 6-inch radiating mid range and an HF tweeter.
Thus, all portions of the frequency range are covered with a dedicated set of speakers. Fender's SFX technology pushes the performance of this digital amp one notch further. Using this tech, you can adapt the tone profile of your amp to the room you're playing in.
In other words, the output gains a much more natural sounding vibe. Add to that two individual channels as well as five different effects, and you get a complete package.

Acoustic players looking for a versatile and customizable gigging combo may have found their amp with the Marshall AS100D. This 100-watt stereo combo offers two instrument channels, a vocal channel, onboard effects, and enough controls to satisfy even the most demanding guitarist.
As we highlight in our full review, the AS100D’s instrument channels feature multiple EQ controls, with contour and phantom power switches. Crucially, they also offer anti-feedback switches, making it easy to neutralize unwanted feedback on the fly without fumbling through your preamp.
While the default tone can sound harsh, slight EQ adjustments can take this thing from chiming trebles to thick, heavy mid-focused sounds. The 16 onboard stereo effects mean this amp can function as an all-in-one solution for gigging acoustic pros.

If you’re like us, the idea of having to carry around a ton of gear to play a solo acoustic gig isn’t very appealing. With the Boss Acoustic Singer Pro, you can have everything you need in one portable package.
It boasts two separate channels (one for your acoustic guitar, and one for your vocals). Each comes with an impressive set of features – making it super easy to personalize your sound.
Great sound doesn’t mean much if it’s hard to hear in a live setting. Even though this may be a pretty small amp, the 120 watts on offer ensures the sound is simply huge! Check out our boss-acoustic-singer-pro-reviewfull review of the Acoustic Singer Pro and see what it can bring to your stage.

Yamaha's THR series of modeling amplifiers represent some of the most interesting choices for acoustic players as well as those who need a versatile electric guitar tone. The acoustic member of this family, the THR5A brings additional tone options to acoustic guitar players worldwide.
It's extremely mobile, comes with built-in speakers and features a wide selection of voices. With that said, THR5A is best used for home or studio recording. Yamaha's VCM technology allows you to get an incredibly natural sounding tone out of a purely digital amplifier.
This way you can get a better recording quality while still enjoying the natural sound of your acoustic guitar. On top of that, the selection of effects is definitely worthy of respect.

Roland AC-60 is a truly compact package that brings all the benefits of quality acoustic guitar amplification in a mobile format. It brings two channels with some pretty unique features.
In terms of power, you're looking at a sensible amount that tops out at 30 Watts in stereo mode. However, Roland has included line outs if you need to expand the setup past its built in 6-1/2 inch speakers. In terms of effects, the selection is somewhat limited, however the ones you do get are pretty well designed.
As a matter of fact, their DSP offers a multiband chorus, which you won't find elsewhere. If you need a solid and compact gigging amp, Roland AC-60 is a good choice.

Whether playing solo or accompanying a vocalist, Fender’s Acoustasonic 40 is a very good choice and one that doesn’t break the bank.
This lightweight, solid-state combo amp is one of the simpler on this list in terms of features and functions, but it does the basic things very well, delivering a clean and natural tone with 40 watts of power on offer. This makes it ideal for smaller gigs, whether coffee house or church hall.
As we mention in the complete Acoustasonic 40 review, one of the highlights is the fact that the two channels (which have combined XLR / 1/4” input for either guitar or mic connections) have separate controls and separate reverb, making it easy to dial in the exact tone you want.

One of the cheapest models on this list comes from the respected German brand Behringer, who deliver a compact amp at very wallet-friendly price. With a stylish but rugged combo amp construction, the Ultracoustic AT108 features 20 watts of power delivered through an 8” speaker, offering enough punch for practice and even small performances.
The addition of an XLR mic input and its own separate volume control will be an added bonus for performers who sing along to their playing. Although it’s a solid-state amp, the tube simulation offers good clarity and warmth, which can be tweaked thanks to the 3-band EQ.
Seriously hard to fault for the price. There’s more on the Behringer Ultracoustic AT108 in the complete review.
What to Look Out for When Buying an Acoustic Amp
Now that we’ve seen what’s on offer, let’s help you narrow things down by looking at what to keep an eye out for when shopping around for an acoustic amp.
Do you go for a tube or solid-state amp? Both variations exist with acoustic amps and the decision will come down to your budget and tonal desires. Tube amps (which use vacuum tubes to increase the power of a guitar’s signal to the speaker) are the more expensive version, but deliver a thick, organic tone with more dynamic response. Solid-state amps (using silicon-based transistors instead of a tube to boost the signal) are usually cheaper and offer a clean replication of the guitar’s tone. Note that, unlike guitar and bass amplifiers, the standard format for an acoustic amp is a combo.
This is the time to define what you are buying an amp for. Is it just practicing in your home? Chances are you won’t need much more than 20 watts of power for this. But as soon as you begin expanding your performances to bigger venues then you’ll need an upgrade in power. While every venue and amplifier are different, around 50 watts of power is ample for most coffee houses, while 100 watts will give you all the output you would need for bigger stages. If you need further power, some amps will allow you to hook up to an external speaker or PA system.
Another important consideration is how many channels your amp offers. If you are practicing alone, one channel will usually suffice. But having a second channel allows you to plug in either a second guitar (or ukulele/mandolin) or a microphone for a vocalist, depending on the model. If this is the case, having separate channel controls is essential, allowing you to tweak the volume, tone and reverb levels of both channels.
As is the case with electric and bass amps, some acoustic amps also offer built-in effects. The most common are reverb and delay, while you will also find popular effects such as chorus and flange too. Some acoustic amps will also feature an FX loop, allowing you to easily add whatever effects pedals you want.
The Final Word

Be sure to read some reviews, watch some videos and – if possible – try out some amps before settling on your perfect solution. Good luck!
