Best Keyboard Amplifier Reviews of 2023

Whether you play keys in a band or you're a soloist, having the best keyboard amplifier is extremely important for live performances. If you've never bought this type of loudspeaker before, though, it can be difficult to know what one is right for your needs. Fortunately, in this article, we'll provide you with all the key information you'll require to make an informed purchase.

Keyboard amplifiers are not the same as electric guitar or bass amps. The main difference is the frequency response. A keyboard, digital piano, or synthesizer is capable of producing notes that are higher and lower on the sound spectrum than a stringed instrument can achieve. As a result, the loudspeaker needs to be able to reproduce these notes clearly and crisply, and this means a wider frequency range is essential. We'll get onto more of the technical information later when we provide you with our helpful buyer's guide.

It's important to note that this piece of kit isn't just important for gigging. It can also be crucial for recording sessions too. Depending on what you need the amp for, then you'll want to focus on certain features. In our guide, we've provided you with a wide range of products. You'll find everything from high-end amps to budget models, as well as everything in between. You'll certainly come across one that ticks your boxes in terms of price, power, size, and sound quality.

Let's now move onto our reviews of the top ten keyboard amps on the market. After our list, you'll find our buyer's guide, where all your questions will be answered. Let's get going!

Here is Our Review of the Top 10 Best Keyboard Amps for 2023 :

1. Peavey KB 1

Peavey KB 1

Many keyboardists have chosen a Peavey for their first amp. Why? Peavey amps have an excellent reputation for being effective at amplifying your keyboard, while also providing you with other features that keyboardists can take advantage of when performing or rehearsing with others.

This Peavey amp is reasonably priced, especially when its quality is taken into consideration. It offers you 20w of power, which is ample for live performances. The sound it delivers is clean, distortion-free, and crisp. It’s got two channels, which each have their own two-band EQs.

Portability isn’t a problem with this amp either. It’s got dimensions of 19.5” by 18” by 13.1”, and it weighs 16lbs. The in-built handle allows you to easily carry it to and from rehearsals or gigs.

+ Clear Sound
+ 20W of Power
+ Portable
+ Reasonable Price
+ Ideal for Gigs and Rehearsals

Why We Liked It - It’s an excellent example of what Peavey does best. This manufacturer’s keyboard line of amps has been popular for decades because each amp offers clean, powerful sound, as well as lots of useful extras.

Amp vs Amp - Keyboard amps are not the same as guitar amps, and you should never let the guitarist plug into your keys amp (or vice versa!). Keyboards and guitars output at different signal levels, so they need different types of input and different types of amp. If you're still sharing an amp with another musician, then you need your own keyboard amp today!

2. Donner DKA-20 Keyboard Amplifier

Donner DKA-20 Keyboard Amplifier

The KC Series by Roland is very popular with keyboardists. And this amp is a perfect example of just why. It's got four channels and delivers 100w of power. This amp performs particularly well on the low end, offering you deep, clear bass reproduction. You can boost the low end even further by connecting a powered subwoofer to it via the Sub Out port.

Another great feature of the Roland KC-200 is its compactness. It can be easily transported, making it ideal for keyboardists who perform live or want a keyboard amp for rehearsals. But there is nothing flimsy about this lightweight amp. Typically for Roland, the build quality is high level, and this speaker will survive more than its share of bumps without any performance issues. It's simply a functional, effective, and durable little speaker that our team loved!

+ Excellent Bass Reproduction
+ Lightweight and Compact
+ Affordable
+ Durable
+ 100W of Power

Why We Liked It - This amp is proof that great things can come in small packages. It can be easily transported to gigs or rehearsals, while it also provides room-filling, 100W of power, and four channels. There's little to fault this great-sounding product.

3.  Behringer Ultratone Kt108 Ultra-Compact 15-Watt Keyboard Amplifier With Vtc-Technology


If you're a beginner or intermediate keyboardist, then this affordable amp from Behringer should be considered. It’s got two channels, 15W of power, and an 8” BUGERA speaker, which all combine to create a great-sounding, powerful, and portable amp.

In terms of customizing and shaping your sound, this amp gives you loads of options. It's got VTC technology built into it, which can be used to add some aggression to your tone. There's also a three-band EQ for even more control over your sound.

To provide you with peace of mind, Behringer offers you a three-year warranty with this product. Of course, it's unlikely that this durable, well-designed speaker will break, but having the warranty means that if anything does go wrong, then you're covered.

+ Control Over Sound Due to 3-Band EQ
+ AUX Input Allows You to Play Sound Through External Speakers
+ Virtual Tube Circuitry (VTC) Adds a warm tube-like effect to your sound

Why We Liked It - For the price, this product is hard to beat. It’s loaded with great features, like VTC technology, two separate channels, and an AUX port. While it might not be the most powerful product on our list, it does sound great, and we think it's perfect as a first keyboard amp for beginners or intermediates.

How Many Inputs? Simple: always go for more than you think you'll need. From the back of the stage (where we're always put!), keyboard players can struggle to hear forward-facing guitar amps. But run a 'line out' to a spare input on your keys amp, and you'll hear them perfectly!

EQ is Vital! On stage, what you hear from your amp won't be the same at every gig. Amp EQ can help make sure your patches sound "right" to your own ears, so you can just focus on playing your killer solos.Make sure the EQ is "post fade", meaning it will only affect what you hear and not alter any DI signals.

Buying Guide

It can always be a bit difficult when choosing a piece of equipment for the first time. How do you know what features to look out for? How do you know how much to spend? These are just a few of the questions you might be asking yourself now. We're going to now provide you with all the key information you'll need to make a wise and informed purchase.


An amplifier will usually feature a preamp, a megaphone, a horn, and a speaker. Its purpose is to amplify your keyboard's output so that it is much louder. You'll need a keyboard amp to be designed specifically for your instrument. That's because a keyboard can produce notes that fall into a broad frequency range. You want it to be able to cover the deep bass notes, all the way to high-pitched piccolos.

A keyboard amp is designed with a keyboard’s sonic range in mind, which is why it’s given this name. But it is also well-suited to other instruments. And if it has several channels, it will often be able to double up as a PA system. This is ideal for singer-songwriters who want to be able to play keys simultaneously as singing.

Other Sound Magnifier vs Keyboard Amplifier

So, what’s the difference between other musical instrument amplifiers and a keyboard amp?

Well, a keyboard amplifier is engineered with this instrument in mind. It means that it will offer low-frequency output to complement the low notes you play on your keyboard. It will deliver crisp highs too.

A keyboard amp needs to provide more range than many other instrument amplifiers because of the range of sound that a keyboard can produce. A keyboard amp will also deliver low distortion and flat frequency. You don't want that high gain, overdrive from a keyboard amp as you would for a guitar. Clarity is the most important aspect of this product.

Now let’s move onto connectivity. Guitar or microphone amplifiers are meant for one guitar or microphone at a time. This isn't the case with a keyboard amplifier, which is equipped with a mixer and two or three inputs so multiple instruments can be connected at once. Each channel will have its own preamp so that different volume levels can be achieved.

Types of Keyboard Amplifier

Generally, keyboard amps will fall into two categories, which will be defined by how much they cost.

  • Cheap/low budget amps

Most low-price keyboard amplifiers are meant to provide equalization controls for the overall output like adding bass, deducting treble, etc.

  • High-End amps

State-of-the-art amps are high-powered. They provide separate equalization controls for each channel.


Speaking about the design, a typical amp features three- or four-channel mixers so that users can plug different instruments into one amplifier. This allows you to amplify several instruments simultaneously through one speaker, cutting down on the amount of equipment you need.

If you perform with several instruments as part of a band, then having a keyboard amp is important. Not only can you plug in your electric piano or keyboard, but you can also connect several synthesizers at the same time. It means that for a gig, you will only need to use one amp, even though you might use a few different instruments.

PA System vs Keyboard Amp

A keyboard amp can also be used as a PA system. As technology has improved, many manufacturers have merged a keyboard amp and a PA system into one product. This has become increasingly common since 2010.

Some keyboard amplifiers have an XLR cable port for a microphone to plug into, and a microphone preamp that allows users to connect a mic and use the keyboard amp as a PA system. In theory, a keyboard amp that includes an XLR mic input, preamp, and a multi-channel mixer could be used inside a small venue.


Using a keyboard amp as a PA system is fine in some cases, but you might be limited in some scenarios.

  • Firstly, it is not an easy task to elevate a keyboard amp like a PA system. PA systems come with a speaker stand and pole into which you can easily mount the speakers. A keyboard amp doesn’t offer this advantage.
  • Secondly, elevating the PA system helps ensure that the output is dispersed equally among the audience while it’s different with keyboard amps. Placing a keyboard amp on a table or raising it a little will only allow the first column of an audience to hear clearly, while the whole venue will not be able to have a good listening experience.
  • Next, PA systems often have a much higher power rating, while digital piano amps usually offer less than 50 watts of power.

Using a piano amp as an alternative to a PA system is okay in certain scenarios but note that you might run into difficulties in some circumstances.

Connecting Subwoofers

We strive to make our reviews as comprehensive as possible. As a result, we’re going to explain how to connect a keyboard amp to several instruments. Read on, as this isn’t the sort of information that you’d find in other review articles.

Many amps have a sub-out jack that allows users to connect an external powered subwoofer for adding extra bass. Note that subwoofers only provide deep bass frequencies, so a user should add full-range speakers for a more balanced sound that isn’t so heavy on the low end.

We’ve now explained everything you might want to know about keyboard amps in our reviews and buyer's guide. If you read this article thoroughly, then you’ll be in a great position to pick the best keyboard amp for your needs.


What is a keyboard amp?

It's quite simply an amplifier that can be used for a keyboard.

Don’t get distracted by the title ‘keyboard amp’, though, as it isn't just for keyboards. They can be used for several instruments thanks to multiple channels and connectivity options. Keyboard amps will also have an XLR input so that you can hook up a microphone and sing while you’re playing the keys.

What are keyboard amps used for?

Keyboard amps are used for reproducing the broad frequency range of electronic instruments.

So, what’s the difference between a guitar amp and a keyboard amp?

A guitar amp is only meant for amplifying the signals within the range that a guitar is capable of playing. In contrast, keyboard amps provide a broader spectrum of frequencies - as keyboard signals are higher and lower than guitar signals - which is entirely out of a guitar amp’s range.

Many keyboard amps can be used for drums, acoustic guitars, and many other instruments, thanks to the wide frequency range that they can reproduce.

These amps are also used as an alternative for PA systems. Some high-end keyboard amps with powerful speakers that include AUX and microphone inputs can also be used as speakers for a DJ or a karaoke party.

There are, however, some drawbacks to keyboard amps, which is why they’re sometimes not well-suited to other uses. Keyboard amps are heavy. This makes them hard to carry, so they're not ideal for traveling musicians. Similarly, PA systems can be easily hooked up to a mounting stand, while you can’t usually elevate a keyboard amp above a typical chair height.

Although many consumers use a piano amp as an alternative to a PA system, it is not meant for public addressing.

The bottom line states that a keyboard amp amplifies electronic instruments’ signals into a broader stage of the sonic spectrum.

What is the average cost of a keyboard amp?

The amount that you’ll spend on a keyboard amplifier will depend upon your budget.
Generally, you’ll find that keyboard amps will fall into three different price ranges. You’ll have budget keyboard amps, mid-priced keyboard amps, and premium keyboard amps.

The budget category includes amps that cost no more than a few hundred bucks. These amps are designed for beginners. They’re ideal for learning, but they do have limitations. The best budget keyboard amps will allow you to perform in very small venues, but they won’t deliver enough power or quality for a larger venue.

Mid-priced amps are suited to intermediate keyboardists who might have just started branching out into live performances. They range in price from a few hundred bucks to close to a grand. These amps are ideal for keyboardists who want to grow on their instrument, as well as rehearse and perform with a band. They will feature lots of connectivity options so you can sing along while playing your instrument.

Premium keyboard amps are the most powerful, as well as the best sounding. That comes at a cost, though. They’ll set you back more than a thousand bucks. They’re designed for advanced keyboardists who perform on stage regularly. They’re also built to last. But, remember, when an amp is as powerful and as advanced as it will be in this category, it will weigh a lot more.

How do I choose a keyboard amp?

Read this guide. Research what’s available. And then you should be in a better position to know what amp to choose. You should also make sure to focus on the following key elements:

  • Build Quality and Portability

A sturdy, rugged design is essential. You should also ensure that you check reviews of an amp before buying it. Why? Manufacturers often make bold claims about their amplifiers’ robustness, but these claims are usually found to be invalid when a keyboardist subjects the amp to regular usage. You want to look out for what materials the amp’s enclosure is made from, as well as check for added extras, such as reinforced corners.

Portability is also an important thing to note while picking your new amp. You want it to be lightweight enough to carry around. And having reinforced handles or wheels can also make transporting your amp even easier. This is an essential feature if you’re going to be taking it on the road.

  • Speaker Size and Power

Here, most people recommend that one look for a highly rated speaker size and power, but that’s not how it works. The user should analyze his needs and then look for the speaker size and power according to it.

For instance, a beginner doesn’t need 180-watts of power with 15-inch speakers. 50-watts of power and an 8-inch speaker would be enough for basic practice.

Choose an amp that suits your needs rather than getting carried away by big numbers.


Most keyboard amps include more than two channels for connecting multiple instruments at a time and separate controls. Moreover, some also include AUX, microphone, and headphone ports.

If a user wants to connect more than two instruments, then he/she should look for an amp with more than two channels. Similarly, if one needs to connect a smartphone or laptop for external streaming, he should look for an AUX port on the piano board.

Effects and Other Features

Keyboard amps are not designed to provide effects, but some high-end products include effects like chorus, reverb, and more.

These effects don’t just apply to your keyboard. If the amp doubles up as a PA system, you can use them for your vocals too.
