Acoustic guitars have a woody and percussive sound that require specialized acoustic amps with extended frequency response. These amps also need to be transparent, to faithfully reproduce the dynamics, attack and sonic nuances of acoustic instruments.

Featured here are the best rated acoustic amps on the market, based on actual user feedback including the most recent reviews and ratings. For this 2022 edition, we retained the price based groupings that we previously adapted, to make it easier for you to see which ones fit your planned budget.

Two-channel acoustic amps continue to be the mainstay of this category, they usually have a mic input in addition to the acoustic guitar input. This configuration makes it the amp a pseudo PA-system, suitable for singer / guitarists. Many of these amps come with HF drivers (tweeters) to better handle the high frequencies of acoustic instruments and even vocals. And this "full-range" tweeter plus woofer configuration is the reason why acoustic amps are closer to PA speakers than conventional electric guitar amps.

Fender Acoustasonic 15 15-Watt Acoustic Guitar Combo Amp
At publication time this was the Highest Rated Acoustic Amp Under $200.

Cons

  • Low volume
  • Mic channel has limited controls
  • Would've been nice if it could run on batteries

Pros

  • Good clean sound with mid-high emphasis
  • 2 Channel (Mic & Instrument)
  • Compact and portable
  • Bedroom and practice friendly volume

The Fender Acoustasonic 15 is a portable and affordable acoustic combo amplifier, it is a 15W combo with a 6" woofer.

Even with its diminutive size, Fender was still able to outfit the amp with 2-channels, one for mic, and the other for acoustic-electric guitar. This makes the Acoustasonic 15 viable as a low-wattage portable PA system, ideal for students who want to play acoustic guitar and sing at the same time.

Channel 1 sports an XLR input jack for mic, and a dedicated volume knob. Channel 2 has a 1/4" input for instrument, with volume and 3-band EQ that includes bass, middle and treble control knobs. The 3-band EQ allows for basic tone shaping, which is important when dealing with acoustic instruments. Channel 2 also comes with a chorus knob, which is an interesting choice, given that most amp manufacturers usually go for reverb.

Given its 6" woofer and traditional cabinet design, don't expect much low-end, but it does a good job of reproducing the highs and mids. The resulting sound is clean with some emphasis on the mid-treble. It can even be used with electric guitars to get good sounding low-volume clean tones.

For a 15W amp, it has good volume for small rooms, but it works best when set to lower volumes for practice. With its limited projection and power rating, this is not a stage amp. But thanks to these limitations, the amp is portable and lightweight - it would've been nice if it could run on batteries.

Interestingly, the amp comes equipped with a 1/4" headphones out, which is quite awkward because acoustic guitars will still be loud even when you're using headphones.

The Fender Acoustasonic 15 is a great budget friendly acoustic amp that is backed by an established guitar brand, highly recommended in this price range.

Fishman Loudbox Mini BT 60-Watt Acoustic Guitar Combo Amp
At publication time this was the Highest Rated Acoustic Amp.

Cons

  • Not meant to be driven too hard
  • Small woofer, bass lacks depth

Pros

  • Full range speaker system with tweeter
  • 2-Channel (Mic and Instrument)
  • Modern Bluetooth convenience
  • Viable all-around multimedia speaker

The Fishman Loudbox Mini BT adds Bluetooth wireless connectivity to its already successful predecessor, while carrying over the same balance of power, tone and portability. This means that you get the benefit of modern wireless audio streaming on an amp that you can use with your acoustic-electric guitar.

Weighing in at 21 lbs., it sports 2-channels, one of which allows for plugging in microphones. It has a 6.5" LF woofer, and a 1.1"HF tweeter, both of which work together to give this amp extended frequency range. The tweeters allow the amp to reproduce the crisp attack of acoustic guitars, resulting in a more natural sound. Given the small woofers, bass doesn't go deep, but it has enough for acoustic-electric guitar use.

True to its name, this 60W amp can go loud, enough to cover small venue gigs. It can also be a great amp for practice and group rehearsals. The extra power and the tweeter makes this a good mic amp as well. And when you consider the addition of Bluetooth connectivity, this acoustic amp can become a capable mini-PA system and all-around multimedia wireless speaker. In this day and age, wireless connectivity has become more of a necessity than a luxury feature.

Note that while the amp has quite the headroom, the small speaker it has means that you're not supposed to drive the two channels too hard. On the other hand, this smaller speaker ups its portability. Other features include built-in chorus and reverb, and it has an XLR DI output for recording or for plugging into a PA system.

The Fishman Loudbox Mini BT is a premium sounding multi-channel acoustic amp with wireless Bluetooth convenience and good portability.

Features

  • Full Range Speaker: 6.5" Woofer and 1.1" Tweeter

Fender Acoustic 100 - 100 Watt Combo Acoustic Amplifier

Cons

  • Can be too trebly
  • Not meant to be cranked hard

Pros

  • 2 Channels with dedicated EQ and effects
  • More effects selection
  • Full range sound via whizzer cone
  • Bluetooth connectivity
  • USB direct recording
  • Well thought out design

The Fender Acoustic 100 is an acoustic amp that combines modern features with elegant looks.

Like most acoustic amps, it has 2 channels, but the extra channel is no longer just an afterthought, both channels have the same input, controls and features. Each channel has a dedicated Combo XLR input, for plugging in a microphone or an instrument. And the two channels have dedicated controls which include phase shift, 3-band EQ, FX selector and FX level. The FX selector in particular offers a lot more effects than you'd expect from an acoustic amp, covering reverb, delay, chorus, vibratone and combinations. This means that you can apply different EQ and effects to each channel, which makes the amp great for using two different sound sources, be it mic and guitar or two different instruments. It can even be good for blending two different pickups from one guitar.

Another interesting feature of this amp is its 8" Whizzer cone. It is basically a tweeter that's built into the woofer, providing increased high frequency response, much like a tweeter, but without taking as much space. As such, it behaves much like a full range speaker system, with more treble definition than conventional woofer only combo amps. This whizzer cone helps give the amp a more natural sound, especially in the highs. The downside to this is that it could be too trebly, for those who prefer warm bass'y tones.

Rated at 100 Watts, this amp can go loud, but with its small 8" woofer - it's not meant to be cranked hard. It also makes sense that you don't max out the headroom since acoustic amps are designed to provide clean tone.

All these nice features are packed inside a stylish looking combo cabinet that gives it a premium furniture vibe. Compared to traditional combo amps, the Fender Acoustic 100 design and aesthetics are well thought out, controls are cleverly hidden from the audience but accessible to the musician, and it comes complete with an integrated handle.

Contrasting its classic furniture like appeal, it features modern enhancements which include Bluetooth connectivity and USB output for direct recording. These enhancements expand the use of the amp, making it viable as a wireless home speaker system and a USB audio interface.

The Fender Acoustic 100 is ideal for those who want a slick looking versatile modern acoustic amp.

Features

Marshall AS50D 50-Watt 2 Channel Acoustic Guitar Combo Amp
At publication time this was the Highest Rated Acoustic Amp from $500 to $1000.

Cons

  • Old release from 2007
  • Limited tone shaping and features

Pros

  • Time tested build quality and reliability
  • Full sounding with clearly defined bass
  • Easy to get good tone
  • Vocals sound good

Marshall is known as the backline of many rock guitarists, but they are in no way limited to that, as evidenced by the popularity and high ratings of the AS50D, a 50 watt 2-channel amp that serves both as an acoustic amp and a small PA system.

At 50W and with two 8" Celestion speakers, this amp is more than enough for smaller venues. You can still use it in larger venues as your stage monitor, and send either the line out, or preferably the balanced DI signal, directly to your mixer.

Being an older release, it lacks quality of life improvements that are found in more modern amps. But being a classic also has its perks, with the AS50D, you know what you're getting - good build quality, reliable performance and good tone - all of which help make it a consistent market favorite many years after its initial release back in 2007.

Compared to modern amps, the AS50D has a fuller voicing, with clearly defined bass frequencies. And this is what makes it appealing especially among experienced acoustic guitar players. More importantly, you don't even need to do much tweaking to get good sounds. Well, there aren't many controls to tweak anyway, with just volume and 2-band EQ. The warmer voicing for this amp also makes it great for deep sounding vocals and nylon string guitars.

The inclusion of phantom power on the XLR mic input means you can use condenser microphones in addition to dynamic mics. It also comes with acoustic guitar friendly effects that include chorus, reverb and anti-feedback controls.

The second channel is a bit of a mess as it awkwardly combines the second Mic input with the RCA auxiliary input using a single volume control. Others have had issues with not being able to make the aux loud enough compared to the other inputs. Note that for a 50W amp, it is a bit on the heavy side, so it may not be a good pick for those who want something portable.

With its big brand backing, impressive specs, and years worth of great user feedback, the Marshall AS50D is definitely well worth checking out - especially if you are into warm acoustic voicings.

Roland AC-60

Cons

  • Old release from 2004
  • Limited control over reverb/delay

Pros

  • Full sounding clean tone
  • Time tested reliability
  • Busking and stage friendly
  • Simple operation, easy to get a good sound
  • Works well with different instruments and vocals

First released back in 2004, the Roland AC60 is one of those few older releases that is still widely used and highly rated. The continued popularity of this amp is a great testament to its quality, practicality and appeal to musicians.

What separates the AC-60 from most acoustic amps is the use of dual speakers, which gives it fuller and livelier tone. And it does so with minimal impact on tonal color, making this a great all-around amp for use with acoustic-electric guitars, nylon string guitars, vocals, keyboards and more.

This is a 2-channel stereo amp with a total of 60 watts power, one channel is for your instrument and the other is a Mic/Line channel. While other amps skimp on their Mic channels, the AC-60 packs it with the same 3-band EQ along with a chorus button. This channel has a Mic/Line button and a phantom power switch, which expands your mic options. The guitar channel has a pickup type button which lets you choose between piezo and magnetic, and a shape button that shaves off some of the mids for a mid-scooped type of voicing.

For its size, this amp doesn't sound thin, it has lows that go quite deep. But if the bass is not deep enough, it has a dedicated subwoofer out. This further establishes the AC-60 as a great amp for performance be it for busking or for stage use. It even has Dual XLR outs that lets you send a mono or stereo signal to a mixing console prior to the master volume, which essentially turns the AC-60 into a stage monitor.

Another reason why this amp has stereo speakers is to make the most out of Roland's iconic stereo chorus effect. The amp also has reverb/delay effects, anti-feedback and a mute button. Note that reverb/delay act as master effects, it applies to both channels.

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

There's a reason why the Roland AC-60 continues to stick, if you want a reliable and versatile amp for acoustic guitar and multi-instrument use, then this is for you.

Fishman Loudbox Artist BT 120-Watt Acoustic Guitar Combo Amp

Cons

  • A little too trebly
  • Effects don't sound as good as the amp

Pros

  • Crisp and clear tone
  • With switchable tweeter
  • 120W gig ready power and features
  • Independent 2-channel controls
  • Expanded connectivity options

Fishman is known as the go-to acoustic pickup maker for many guitarists and guitar manufacturers. So it only follows that they know what a good acoustic amplifier should be like. The Loudbox Artist BT is one of their best rated offerings, a gig-ready 120W combo amp,

120 Watts of power along with a 1 x 8" woofer and 1 x 1" tweeter add up to give this amp more than enough volume for most small to medium sized venues. And it does all this while still being reasonably portable. More importantly, the tweeter really helps in giving it Fishman's signature crisp and clear tones.

The highs are very detailed, emphasizing percussive attack on the strings. And since it has a lot of headroom, the amp can go really loud without muddying up the sound. To cater to those who are into warmer tones, Fishman equipped this amp with a tweeter button. This turns off the tweeter to make the amp sound more like a traditional woofer only combo amp.

It follows a 2-channel format, with dedicated combo XLR input and controls. This means that there is no better channel, both have the same features and parameters so you can tweak each channel differently. This means that you have different settings that suit different inputs, be it an acoustic guitar, keyboard, violin, mic and more. Factor in its 24V phantom power option, and you have a full pledged mini-PA system.

The Loudbox Artist BT comes packed with various effects, including different types of reverb and delay, along with chorus and flanger. The built-in reverb effect sounds nice, very useful when playing outside. The other effects are unfortunately not as good, but at least they are there when you need them. This iteration improves on its predecessor by adding Bluetooth streaming functionality, a feature that is becoming standard on most modern amplifiers.

If you're looking for a gig-ready 2-channel acoustic amp then check out the Fishman Loudbox Artist BT.

Features

  • Full Range Speaker: 8" Woofer and 1" Tweeter

AER Compact 60/4 60-Watt Acoustic Guitar Combo Amp

Cons

  • Lacks anti-feedback control
  • No modern features

Pros

  • Sounds big and loud for its compact size
  • Detailed highs and lows
  • Compact and portable profile
  • Stage ready input and output options

AER is well known among acoustic guitar instrumentalists for its combination of portability and good quality tone, they also have virtuoso Tommy Emmanuel to thank for their popularity. The Compact 60/4 is one of their best seller acoustic amps, a 2-channel 60 Watt amplifier with built-in effects and DI output.

Having a good sounding amp in a small package is every guitarist's dream, this is exactly what the Compact 60/4 delivers. For a small amp, it sounds really big, with high fidelity mids and highs. It also has detailed bass, which is often a problem among small amps. Because of how detailed the sound is, every nuance of your playing and dynamics are well represented, hence the reason why this amp is a favorite among those who play instrumental acoustic guitar music.

Acoustic-electric guitars are meant to plug into the first channel. It has a high and low selector switch for accommodating different pickup types, and it has a color switch that enables a more scooped style voicing. In addition to all that, it has gain and 3-band EQ knobs. The second channel has a combo XLR input allowing for more sound sources like other instruments and mics, it also has 48V phantom power support.

The effects section has 3 knobs which lets you control pan, level, and select rotary switch that lets you choose from 2 different reverb types, delay and chorus. The reverb and delay effects sound really good, I'd describe them as close to studio quality, especially the reverb. The chorus effect is OK, mostly because I'm not too fond of using modulation effects on acoustic guitars.

At the back you'll see its myriad of input and output options, including a stage friendly DI output and an Aux input with level control.

Anti-feedback control is noticeably lacking, and it would've been better if it could run on a built-in rechargeable battery, and if it had modern features like USB recording and Bluetooth connectivity. But even without all these features, the amp does a great job of faithfully reproducing the natural sound of acoustic guitars.

If you're looking for a premium sounding portable amp that even pros rely on, and you have the resources to invest, then check out the AER Compact 60/4.

Mesa/Boogie Rosette Two:Eight 300
At publication time this was the Highest Rated Acoustic Amp Over $1000.

Cons

  • Requires a bit of an investment
  • Steeper learning curve

Pros

  • Rich and natural tone
  • Extensive EQ and tone shaping controls
  • Loud with high headroom
  • Two woofer plus switchable tweeter
  • Stage ready tilt-back system and connectivity

Mesa/Boogie is well known in electric guitar circles, especially among those who are into rock and instrumental music. They have since expanded into acoustic guitar amplification, and thanks to the Rosette Two:Eight, they are raking in plenty of good market feedback.

Rated at 300 Watts, this amps has ridiculously high headroom. This is paired with two 8" speakers and a dome tweeter, which gives the Rosette a full and rich tone that stays clean at higher volumes. At default settings, it lacks the crisp brightness that others offer, but to my ears, it sounds more natural and closer to what acoustics really sound like when unplugged. Anyway, the amp does have a myriad of EQ and tone shaping control, along with switchable tweeter, so it can also have that crisp flavor after some tweaking.

Speaking of controls, this amp has two independent channels with dedicated volume, EQ and other tone shaping controls. Speaking of EQ, each channel gives you 4-band EQ control along with high pass filters, allowing for in-depth tone shaping. The EQ has low mid and high mid controls, both having their own gain knobs and frequency sweeper, so you can precisely boost or cut frequencies as you see fit. Channel one has a switchable XLR input, in case you want to plug-in a microphone.

The downside to all these controls is that there's a steeper learning curve, but the reward of familiarizing yourself with each one is good customizable tone.

Other features include multiple reverb types, and a built-in parallel effects loop with dedicated FX send knob. There are more controls and input/output options at the back of the amp, making it truly stage ready in terms of functionality. The amp comes in a traditional looking combo design, but with an adjustable tilt back system.

If you are looking to invest in a boutique quality amp, then check out the Mesa/Boogie Rosette Two:Eight.

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. This is why you will sometimes see customer reviews in which a new acoustic amp owners says something to the effect, "it's not as loud as I 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.

Full Range Speakers

Acoustic amps often feature full range speakers, meaning they come with a LF driver or Woofer for low to midrange frequencies, and a HF driver or Tweeter for high frequencies. This configuration helps in reproducing the percussiveness of acoustic sound, and its high-end zing. This also makes acoustic amps viable for use with other miked instruments and vocals, which in turn makes them viable mini-PA systems.

PA via a Preamp as an Alternative

Instead of using a dedicated acoustic guitar amp some guitarists plug to PA system via 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.

Powered PA Speaker as an Alternative

Powered PA speakers are full range speakers that often come with built-in multi-channel controls, making them viable for mics and instruments like acoustic-electric guitars. These speakers are versatile enough to handle different type of electronic instruments, they also provide good sound and ample projection, but their main downside is lack of anti-feedback control and effects.

Best Acoustic Guitar Amp Selection Methodology

The first Edition was published in 2016 and the current Edition was published on May 11, 2022.

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 2022 edition, we ended up with 47 of the most popular acoustic amps on our short-list (most of them are available to see in our public database). Then we collected and analyzed over 8,900 of the most relevant forum discussions, reviews, recommendations and ratings. These data were then analyzed and processed by 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.

For this edition, we divided the resulting list into brackets according to price bracket:

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.

Mesa Boogie is the only maker

Mesa Boogie is the only maker to post on there website the fact there acoustic amp is class d. This is a big deal for old school players who prefer transformer power. Shame on the other manufacturers for making it so hard to find out what’s inside.

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.
