Acoustic guitar amps are especially designed to bring out the natural sound of acoustic instruments, making them good investments for those who want to make the most of their acoustic-electric guitars.

Here we look at the best rated acoustic amps, based on analysis of the most recent reviews and ratings up to mid July 2020.

Many of these acoustic amps are equipped with HF drivers (tweeter), which widens their frequency range, making them suitable for other acoustic instruments, be they miked or equipped with pickups - from ukuleles to violins to percussion. The wider frequency range also makes these amps suitable for use with vocals, adding to their overall value.

Both steel string and nylon string players love this amp. There are reports of the amp working well in small to medium size venues, as well as in church sanctuaries.

Cons

There were no consistent complaints about this amp in owner feedback and reviews.

Roland AC-60

This is a 2-channel stereo amp with a total of 60 watts power. As with the AC-33, one channel is for your instrument and the other is a Mic/Line channel.

The AC-60 is not simply a more powerful version of the AC-33 - it has a different feature set designed more for stage and studio use without the AC-33 features designed for buskers and street performers.

It has a dedicated subwoofer out which means with the addition of a subwoofer this amp should produce a solid sound with an acoustic bass as well - some people also use subwoofers with this amp for regular guitar because they like the sound of it.

There is also an identical but rosewood colored version with the model number: AC-60RW on Amazon.com.

Dual XLR outs let you send a mono or stereo signal to a mixing console prior to the master volume when using the AC-60 as a stage monitor.

Features

  • 2 channels
  • Subwoofer Out
  • Anti feedback controls
  • Built-in Reverb & Chorus
  • Mute switch for silent tuning
  • XLR/Mic input with phantom power
  • Switch between magnetic and piezo pickups

Specifications

  • Power Rating: 60 Watts (30W + 30W)
  • Amplifier Type: Solid State
  • Channels: 2
  • Master Volume: Yes
  • Inputs: 1 x 1/4" instrument switchable between piezo and magnetic pickups, 1 x combo XLR/1/4" with 48V phantom power, 2 x TRS 1/4" AUX in, 2 x RCA AUX, 2 x 1/4" Footswitch for effects and anti-feedback, 1 x 1/4" effects return
  • Outputs: 1 x 1/4" stereo headphone jack, 1/4" TRS DI/Tuner out, 2 x XLR
  • Controls: Guitar channel - switch between Piezo & Magnetic pickups, Shape switch to boost low & high and cut mid frequencies, Mic/Line channel - 48V phantom power switch, Both channels - Volume, Bass, Mid, Treble, Chorus switch + Chorus control, Reverb control, Anti-feedback, mute button
  • Speakers: 2 x 6.5"
  • Weight: 21 lbs. 10 oz.
  • Dimensions: 10.56" x 15" x 10.69"

Pros

Not only do guitarists give this amp positive reviews citing the clarity and tone of the AC-60, but I've also seen violinists using both mics and pickups saying the same. Customer reviews also rate it highly when used both as a primary amp and as a stage monitor. It also received positive citations when also used for vocals. It continues to be a favorite for those looking for an all-around acoustic amp.

Cons

A couple of people complained that the Reverb can't be applied to one channel only - it goes on both channels at the same time. Another person complained that the two XLR outs sum both channels meaning that you can't send guitar and vocals separately to a mixer but that is an uncommon setup that few people will need. A few people said it wasn't as loud as they expected - there are similar comments about most acoustic amps.

Overall

The combination of features and clarity of the sound make this a good buy at just under $500.

And this iteration improves on its predecessor by adding Bluetooth streaming functionality, while retaining Fishman's signature crisp and clear tones.

Much like most acoustic amps, it follows a 2-channel format, the main difference being the addition of a 24V phantom power, which allows it to work with condenser microphones. This feature expands your miking options and allows for improved miking of various acoustic instruments.

Finally, the Loudbox Artist BT comes packed with various effects, including different types of reverb and delay, along with chorus and flanger.

And most, if not all of them, agree that the Loudbox Artist BT sounds really good for both vocals and acoustic-electric guitars. The ability to use condenser mics is also appreciated, especially for those who already have a condenser mic in their tool kit. It also surprises many users with its output volume, which can get really loud.

Cons

Speaking of being loud, some users caution that setting the amp too loud is not a good idea, as it can reduce the clarity of the sound and even damage the amp itself when cranked for too long. There are some who aren't as impressed with included effects.

Overall

If you're looking for a reasonably portable acoustic amp with condenser mic compatibility, then this is for you.

Things To Consider When Buying An Acoustic Guitar Amplifier

Acoustic guitar amps are quite different in nature to electric guitar amps, so if this is your first venture into getting an amp for your acoustic instrument, please read the following carefully to help ensure you get the best possible amp for your needs.

  • Tonal Differences Between Electric and Acoustic Guitar Amps

    An electric guitar amp is meant to color the sound in pleasing ways and to be a significant part of your tone, whilst an acoustic amp is meant to reproduce the sound of your instrument as accurately as possible with as little coloration as possible - this is referred to as 'transparency'.

    Electric amplifiers allow you to really crank them up usually introducing harmonic distortion as they get really loud. Because this is unwanted in an acoustic amp they will typically limit the volume before any significant harmonic distortion is introduced which leads to an acoustic amp of the same power rating as an electric amp not quite sounding as loud. You will often see customer reviews in which a new acoustic amp owners says something to the effect, "it's not as loud as I expected" - which of course, is to be expected.

  • Microphone / XLR Input Channels

    If you are going to sing through your amp while playing then there are a couple of important issues to consider.

    Firstly, if you use condenser mics then you'll need to get an amp that provides phantom power (unless your mic uses batteries). Different amps provide different levels of voltage with the most common being 15V, 24V and 48V. Check to make sure the amp you want is compatible with the condenser mics you intend to use. If you only use dynamic mics like the SM58 then this isn't an issue for you. For more information on microphones see our guide to The Best Live Vocal Mics.

    Secondly, some amps have completely independent channels for microphones and instruments whilst others share features between channels such as effects and DI outs. Read the details of each amp carefully to ensure it has the channel configuration you need for simultaneously playing instruments and singing through it.

  • Feedback Detection / Prevention

    The threat of feedback is an ever present concern when using acoustic amps, particularly with acoustic guitars because they resonate so well. You can run into problems at high volumes and sometimes at lower volumes depending on the acoustics of the room you're playing in. The simplest solution is to adjust the EQ but getting an amp with anti-feedback features will make life easier for you in the long run. Different amps take different approaches to the problem but in general Notch Filters are more effective than phase switches.

  • PA via a Preamp as an Alternative

    Instead of using a dedicated acoustic guitar amp some guitarists plug into the PA system using an acoustic preamp. Note that due to the high impedance of pickups you can't plug directly into your mixing console without going through a preamp first, and you should use as short of a cable as possible from your guitar to the preamp. You can learn more about this in our guide to Acoustic Preamps.

Best Acoustic Guitar Amp Selection Methodology

The first edition was published in July of 2016 and was written by Jason Horton. The latest edition was published on July 13, 2020 written by Alexander Briones with contributions from Jason Horton.

We looked at all of the acoustic amps specifically designed for guitar that were available at major online music gear retailers in the USA. Note that we did not include modeling amps that provide models of acoustic amps despite the fact that some retailers include modeling amps in their acoustic amp category pages.

For this 2020 update, we ended up with 34 of the most popular acoustic amps on our short-list (most of them are available to see in our public database). Then we found and collected over 4,900 of the most relevant reviews, recommendations and ratings, including the most recent ones up to mid July 2020. These data were then analyzed and processed via the Gearank algorithm to produce rating scores out of 100, which allowed us to narrow down the list to what the market considers to be the best.

We then divided the resulting list into brackets according to their power rating, and for this update, we changed the power rating sections to:

Comments

I have the fishman loudbox

I have the fishman loudbox artist. It's okay sounding but the build quality is so bad I will never buy another fishman product. It's made in China. And generally that should be okay. But after a couple of weeks of use the volume knob started making all sort of hiss and noise, and then after a couple of months the exterior of the cabinet starting peeling and crumbling. It's made from some soft or spongy synthetic material. I'm getting rid of this and going for the Mesa Boogie.

What about the Mesa Boogie

What about the Mesa Boogie Rosette? How does it compare to the Fishman Loudbox Pro & AER?

The Mesa/Boogie Rosette Two

The Mesa/Boogie Rosette Two:Eight made it onto our recommended list this year and it is currently the equal 2nd highest rated amp in the over 100 watt category along side the Fishman Loudbox Performer.

I'm not sure which one of the AER amps you're referring to but you can see our ratings for their amps here.

what about the Crate

What about the Crate Acoustics? i have seen used ones- how do they rate?

They didn't make the short

They didn't make the short-list the last time we updated this guide, but if they are widely available in the USA when we next update then they might make the list.

Regarding schertler dealers

Regarding schertler dealers in the USA. Django books in Seattle sells them and offers a 45 day return policy and free shipping. Generally when you call you'll get the owner, Michael Horowitz, who always has impressed me as very intelligent and also knowledgeable about the products he sells

Sir... When I watching

Sir... When I watching YouTube l was inspired by a TED x guy doing percussive guitar...Usman Riaz...he played guitar just only fingering on Fred board without striking strings... How can we amplify acoustic guitars like that...what are the effect pedals you preferred...can you please help me...I have no idea about it...please send me a email: vssebastian723@gmail.com

I'm not sure exactly which

I'm not sure exactly which gear Usman Riaz uses, but a few years ago I asked a similar artist, Jon Gomm, what gear he used and he gave me a complete rundown in this article I wrote for GuitarSite.com: Jon Gomm Rig.

I hope that helps.

You've missed quite a lot of

You've missed quite a lot of quality acoustic amps and the biggest speaker size you've reviewed is 8". An 8" speaker is never going to be enough for a large venue without DI no matter what your review says. An 8" speaker imo is a practice amp! You'll need a 12" or a 15" to play a big venue without DI. You simply can't get a proper bass response out of an 8" speaker. If you could then PA systems in clubs would have 8" speakers!

What about:

• SWR Acoustic Amps (California, Strawberry, Natural, Baja)
• Genz Benz - Shen 150LT and Shen 300LT - much more than 100W!!
• Acoustic Image TEN2
• Trace Elliot/Acoustic TA100 / TA200
• Carvin AG300

Saying that, all of those amps above are quite expensive. How about a Trace acoustic TA50R 'slaved' to a Carlbro Sherwood Classic 100w (15" speaker) - that rocks!

Or simply buy an acoustic preamp (pedal or rack) and plug it into a Mackie SRM450. That will blow away any amp in your review list......

In all the large venues I've

Thanks for your feedback JazzyJ.

In all the large venues I've worked in from indoor halls to outdoor amphitheaters, either as a performer or in the tech crew, no acoustic amp would have been sufficient on it's own. The standard practice in these situations is to either take a line-out (DI out preferably) or to mic the amp. In other words, in large venues the amp serves as an on-stage monitor where the PA and its Front of House stacks with large 15" and sometimes bigger cones being used to provide most of the amplified sound for the audience.

I'm pretty sure that most of the amps you mentioned were included in our survey, but didn't meet our availability criterion as mentioned in the Methodology section above or didn't have high enough ratings to be short-listed. We've since relaxed the availability rule a bit to include manufacturers like Carvin which mostly sell direct so they will be included in our short-list when we next update this guide. Some of the other amps you mentioned are mostly available second hand and people can look for them on reverb or ebay, but I'll make sure we check out the latest from those brands when we next update this guide.

Your idea about using an acoustic preamp in combination with a powered PA speaker is a good one - I see many acts in my area doing that or using a preamp and going direct to the PA these days.

We didn't rate the Rivera

We didn't rate the Rivera Sedona dual electric/acoustic amps back when we first published this guide because there was only limited availability of them from US retailers at the time - possibly because they're significantly more expensive than standard acoustic amps.

But thanks for asking the question - we'll make sure to include Rivera Sedona in our music gear database when this guide is next updated - that may result in them being included in this guide given how highly they are spoken of by people that review or comment about their experiences using them.

It is very useful, but in my

It is very useful, but in my opinion would be better to have more precise gradation. If I can suggest groups could be divide to up to 30W, up to 80W, up to 120W and more than 120W.

Thank you dodo - we will take

Thank you dodo - we will take your suggestion into account when we update this guide - this kind of feedback is quite useful!

Hi Darrel,

Hi Darrel,

The above report was not based upon personal preferences as your comment would seem to imply, rather it was based upon the criteria set out in the Methodology section above.

One of the criteria was that an amp had to be available at major online music gear retailers in the USA. At the time of publishing both this guide and this comment, Schertler amplifiers were not available at Guitar Center, Musicians Friend, zZounds, AMS, Sam Ash, B&H, or our sponsor Sweetwater.

It seems that in order to buy a Schertler amp online from within the USA you currently either have to go to an overseas music gear specialist such as Thonmann (31Kg/~68lbs shipping weight limit), or to a 3rd party seller via services such as Reverb, Amazon or eBay.

Before buying through any non-standard process, I would check with the manufacturer to see if I would get a valid warranty and where I would have to send the amp if it ever needed to be repaired.

BTW - if anyone does know of an authorized Schertler dealer in the USA, please leave a comment about them here.

Where is the ZT Lunchbox

Where is the ZT Lunchbox Acoustic? Much more natural sound than the Fishman Mini, which it compares to in size, cost, and performance but not wattage. Wattage is subjective - it doesn't always correlate to volume.

The ZT Amplifiers Lunchbox

Thank you very much for asking about that Steve because you've given me the opportunity to explain what some people might have thought was an accidental omission on our part - it was not.

The ZT Amplifiers Lunchbox Acoustic failed to get past the first phase of our screening process because it had too many negative customer reviews, many of which complained about it not being loud enough for a 200 watt amp.

ZT Amplifiers chose to market the Lunchbox Acoustic using the higher Peak Musical Power rating of 200 watts instead of using the industry standard for guitar amps which is Root Mean Square (RMS). Had they chosen to promote it using a lower RMS power rating then it's reasonable to think that it wouldn't have attracted so many complaints about the lack of volume.

The net result was that the Gearank algorithm was only able to give the Lunchbox Acoustic a Gearank score of 78.

In the interests of transparency I have included the Lunchbox Acoustic in our public gear database so everyone can see its Gearank score along with all the other amps.

Hi John - at the current time

Hi John - at the current time we are only providing overall ratings with the Gearank algorithm, for now you'll have to evaluate the Lunchbox Acoustic amp the old fashioned way by reading what users have to say in the comments here or on websites such as Harmony Central and Gearslutz.
