Acoustic guitar amplifiers are all about keeping the natural clean tone, while removing bothersome and unwanted distortion or tonal variations out of the game. In that sense they are the opposite of what you would expect from electric guitar amps.
Here is a selection of some of the best acoustic guitar amps. While it is clearly not all-inclusive and preferences may vary, then the list attempts to maintain a certain amount of objectivity in bringing out the best of the best.
1. Marshall Acoustic Soloist AS50D Guitar Amplifier
First place on the list of best acoustic guitar amps goes to Marshall AS50D 50 watt Acoustic Guitar amp. While Marshall is renowned for producing great amps for distortion and overdrive seeking rock guitarists, then this acoustic guitar amp is paradoxically the best in providing the exact opposite.
This amp with its 2 channels with independent EQ brings you some of the finest reverb and digital chorus, while the 2×8 inch 50 watts of power should perfectly suit for anything from rehearsals, recording material, as well as live gigging. Plus if need be you could always go for the 100 Watt version. The anti-feedback notch filter does its job perfectly as well.
2. Fishman PRO-LBX-600 Loudbox Artist
This powerful 120 Watt amp provides a dual digital effects section along with independent channel and effects level for Chorus, Delay, Flanger, Echo, Slap Echo and Reverb.
Fishman is renowned for its superb clean tone, and this is due to its highly regarded feedback-fighting controls, valued by many musicians searching for the perfect sound for their live shows.
The drawback might be that it isn’t the lightest amp and you don’t really need 120 Watts that often, but all in all the Fishman PRO-LBX-600 lands on the second place.
Third place on the list goes for the somewhat smaller 30 watt Roland AC-60. This amp boasts some great delay and reverb with footswitch control, while the built-in auto anti-feedback controls do a great job in keeping your clean tone even at maximum volme.
The maximum volume is quite enough for the rehearsal room, as well as smaller live shows, but with its 2×6.5” 30 Watt speakers the Roland AC-60 doesn’t quite match the Marshall AS50D nor the Fishman PRO-LBX-600, and that’s why it lands on the third place.
The fourth place on the list goes to the reliable, powerful, lightweight and easily transportable Aer Compact 60. The amp also provides two channels with triple/dual band equalizer and 4 digital effect presets, with delay, chorus and two sets of reverb.
The amp packs quite a punch for its 60 watts and the tone it provides is natural and clean – just like you would expect from an AER amp. A great all round acoustic amp. Plus if you need a bit more power you could also go for the 100 Watt AER Domino 3.
Coming in at number five is the 150 watt Fender Acoustasonic.
While you’d think this amp would be on the heavy side then you are wrong. It is quite lightweight and versatile. All of which make it into an almost perfect amplifier for live gigs. The Fender Acoustasonic 150 provides you with two separate channels for vocals and guitar and a variety of effects.
Whats more, the Voicing control allows you to simulate the tonality of a dreadnought, parlour and jumbo acoustics, while it can be equally turned off as well for the sake of a crystal clear pure tone. The great thing about this amp is that it also has Blackface, tweed and British amp settings, which would take away the need for a second amp for electric guitar. The flexibility of this amp puts it into the fifth place.
Dean Markley AG50-DS4 is an amplifier that succesfully mixes value for money with great sound quality and a cleanly transparent tone. It also packs reasonable amount of power with its 50 watts in order to be one of the best acoustic guitar amps for both the rehearsal room, as well as for smaller live shows.
While Dean Markley AG50-DS4 isn’t quite as good as the Marshall AS50D, then it still works well as the budget version that provides more or less the same.
This 100 watt amp with a 10” speaker from Peavey offers quite a lot for its relatively small cost.
The amp comes with a two-band EQ on channel two, while offering effects like chorus, reverb and delay. All in all it offers up to 8 effect presets, as well as a mic preamp and an onboard tuner along with a Notch Filter.
While the amp offers quite a bit in effects presets and works well for live shows, then it perhaps does not match its more expensive counterparts in sound quality and in the clean tone parameters.
This powerful 150 Watt amp from Vox comes with a lot of features, similarly to the Peavey Ecoustic E110. For example it offers two channels, which are Tube Pre and Normal and both come with a 3-band EQ. Volume, Reverb, Color and a Chorus provide great ability for tone shaping, while the anti-feedback filter comes handy during live shows, for which this 150 Watt 6.5” speaker amplifier suits wonderfully.
Overall VOX AGA150 is quite a bit more expensive than the Peavery Ecoustic E110, so it is a tough call on which to prefer.
What makes this amp worthy of this best guitar amp list, is that it is highly portable and can even run on battaries.
In a way its an acoustic or acoustic electric counterpart of the Roland Micro Cube amp, which makes it into a perfect practice amp and good for playing at a place where you don’t have a direct power supply.
The Yamaha THR AMPS THR5A also features 5 mic models, and effects presets offering delay, chorus and reverb. A great all round small practice amp.
This relatively powerful acoustic guitar amp from Crate offers a pair of 8-inch High Fidelity Poly-cone Speakers, along with a 5-band equalizer, tweeter with level control, 3 channel digital reverb and a feedback elimination circle.
All of this makes this amp suitable both for the rehearsal room, as well as to playing smaller gigs every now and then. But beware that this amp weighs quite a bit, so carrying it around isn’t that pleasant.
A downside with this amp is that it costs a bit too much for an amp of this quality, but then again the build quality and durability on the other hand is very solid.
