Here’s our guide to the best keyboard amps on the market right now so you can turn your music production into a professional and powerful sound.

Behringer Ultratone K900FX

Behringer Ultratone K900FX

Coming in at number one on our list is the Behringer Ultratone K900FX. It’s the best keyboard amp because it’s a compact little keyboard that looks like a speaker. 

But don’t be fooled – this isn’t just an amp that can improve the sound you produce on your keyboard. 

In addition to that, it can be used to create other unique sounds that will enhance your music production overall.

Benefits

  • This keyboard amp is a 90-watt 3-channel PA system. All the channels have their own controls and volume, which is great if you want to play multiple instruments.
  • It has a digital FX processor that contains 100 presets, including delay, pitch shifter, reverb, and other effects that can make your music production more interesting.
  • There’s no doubt that speakers are important for keyboard amps and this one comes with a 12-inch Bugera woofer.

Extra Features

  • If you want to connect a microphone to the amp you can do this with ease, thanks to the XLR mic input.
  • There’s even a CD input so that you can play music along to your favorite songs. Karaoke night, anyone? Or perhaps a practice session with your bandmates?
  • Whether or not you’re in a band, there will come a time when you want to play your keyboard on your own without being heard. You can easily do that with this keyboard amp because it has a separate headphone output.

Drawbacks

  • Some people who’ve purchased the product have mentioned a hissing or popping sound, often occurring when the amp is turned on or off.

Buying Guide

This keyboard amp costs just over $250. It’s a quality, well-made amp that can benefit you if you want to connect many instruments to it. 

It’s also nice and easy to carry around. It should definitely be on every serious muso’s wish list for the best keyboard amplification.

Buying Guide

Drawbacks

  • Some people have complained that the volume has to be pushed to reach a high enough level. So, if you like having loud volumes when you play or create music, then this is a product that won’t make the cut for you.
  • Unfortunately, this item is currently out of stock on Amazon.

Peavey KB 1 20W Keyboard Amp

Peavey KB 1 20W Keyboard Amp

This Peavey keyboard amp does have a few limitations, such as when it comes to its power and channels – it has two channels instead of four that are present in other products in this buying guide of the best keyboard amplifier reviews. 

It’s worth bearing in mind that many keyboard amps will have more than one channel to enable you to plug in several keyboards or instruments, as well as microphones. 

Not having this in the Peavey keyboard is a con, but don’t let that prevent you from checking it out anyway. 

You really should because it does have some great features. Let’s look at its benefits.

Benefits

  • If you like making bass sounds, then this keyboard amp will be a good match for you as it has an extended range speaker that produces more bass.

Extra Features

  • It comes with a convenient built-in handle to make it highly portable so you can carry it with you whenever you’re headed to band practice, without a fuss.

Drawbacks

  • It doesn’t have an input for your laptop or iPod. So, if you’re looking for something a bit fancier and professional that has extra frills, then this isn’t for you.

Buying Guide

You can expect to pay just under $150 for this keyboard amp. It might not have a lot of frills, but it certainly gets the job done! 

It’s especially perfect for you if you’re starting out as a keyboard player or are learning how to play it.

Roland Mobile Cube Battery-Powered Stereo Amplifier

At first glance, this Roland keyboard amp looks like an old-school stereo with its speakers, but it’s got a lot to offer.

Benefits

  • You do have a lot of options when it comes to this keyboard amp as it’s highly versatile. You can use it for an acoustic and electric guitar, keyboards, and even for MP3 and CD playback. This means you can play along to your favorite tracks, which is a fun feature that can also prove useful if you’re learning how to play the keyboard.
  • The guitar compatibility is a very nice bonus because you can’t always get the right sound when using a keyboard on a guitar amp. So, with this one, you don’t have to worry.

Extra Features

  • This amp can run on batteries and these can last you up to six hours, depending on how loud you want to play your music. This makes it a great versatile item to have if you like playing in different settings because you don’t have to worry about hooking your amp up to a power source.

It’s also the lightest in our guide, weighing only around five pounds. These features make it really easy to transport, like when you go to play your live shows.

Drawbacks

  • It doesn’t come with an AC adapter included, which is a bit of a con if you want to power it with electricity, but it makes up for that by having batteries included in the pack. That means once you plug it in, you can start playing it without delay.

Buying Guide

The Roland Mobile keyboard amp costs $179.00. 

Although it’s small, it offers decent features and can be taken anywhere as well as played for a long time thanks to its good battery life. 

It’s an awesome stereo keyboard amp.

Now that we’ve looked at the five best keyboard amps in our buying guide, let’s consider some important questions you might have if you’re interested in purchasing a keyboard amp.

Keyboard Amps FAQ

Portable Keyboard Amp

Can you use a guitar amp for a keyboard?

This is a common question that people often want answered. 

If you have a keyboard and a guitar amp, you might wonder if you can just use those together, but, unfortunately, the answer is no

Even though it’s tempting to plug into your friend’s guitar amp because it’s just so convenient, it’s not worth it.

The reason why you should avoid the temptation of doing this is because you won’t get the same kind of sound from a guitar amp that you can from a keyboard amp. 

When it comes right down to it, a guitar amp simply won’t be able to meet the same quality standards of a keyboard amp. 

This is because a guitar amp has speakers and controls that are built in such a way that they will make the most of the guitar instrument’s frequency range.

If you are playing a keyboard you will need much more from an amp when it comes to frequency. 

For example, it has to have larger frequencies so that you can create a variety of tones and sounds that are like the ones you would be able to achieve from an electronic keyboard. 

Ultimately, a guitar amp will just limit what you can do as a keyboard player.

If you want to play guitar and keyboard, then consider investing in a keyboard amp that enables you to play guitar on it, such as the Roland Mobile Cube Battery-Powered Stereo Amplifier mentioned in this buying guide.

What is the difference between a guitar amp and a keyboard amp?

Keyboard And Guitar Amps

In the above section we touched on some differences between guitar and keyboard amps, such as when it comes to their frequency ranges. 

However, there are other differences between them that you should know about.

  • A keyboard amp is a regular amp that amplifies the sound produced when you play a keyboard. It works with the use of an electronic amplifier and loudspeaker, and as you can see from many of the keyboard amps that are featured in this buying guide, they often have a few channels.
  • A guitar amp is an amp that will enhance the guitar’s sound, whether it’s acoustic, bass, or electric. It will usually make use of a separate speaker in order to do this, while a keyboard amp will have the speaker built into it.
  • In addition, a guitar amp will have a single input, while a keyboard amp will have many different inputs that enable you to play more than one keyboard. That’s an especially valuable feature if you’re in a band and want to connect multiple keyboards to the amp.
  • When it comes to distortion, there are also some important differences between the guitar and keyboard amps that you should know about. Guitar amps will change the frequency range and actually distort the sound that’s produced. They do this to add richness to the type of sound that’s produced by the guitar. Keyboard amps, on the other hand, simply copy the input signals. To make sure they’re mimicking the sound as accurately as possible, they will have low distortion to keep the sound precise and clear.

How to plug a keyboard into an amp?

A keyboard can be plugged into an amp very easily. You’ll first need to determine if the device is mono or stereo, although many keyboard amps will be mono. 

This means that they only have one powered speaker. To connect the keyboard to the amp, you’ll look for the line output that is named L/Mono. 

This is usually just a ¼-inch jack, which means you’ll have to use a common male ¼ inch to male ¼ inch cable for the instrument, as Dummies explains.

What happens if you don’t have a line output? 

You’ll have to connect the amp using the headphone jack, but make sure you get a cable that has a matching connector to the one on your headphone jack, with the mono ¼ inch plug on the other end, as Dummies reports.

Why do you need an amp for a keyboard?

If you’ve purchased a keyboard and someone mentions that you should have an amplifier, your first thought might be, “Do I really need it?”

Well, it really depends on what you need the keyboard for. 

If you’re keen on producing music and want to play your music to a live audience, an amplifier can make things a lot easier for you instead of relying on a PA. 

This is because you will have much more control over the music and not have to depend on what you can get on stage that day to amplify your sound. 

This can totally change how well you perform.

That said, even if you’re not playing music live, a keyboard amp can be highly beneficial for you if you’re producing music in a studio. 

This is because a keyboard amplifier will have full-range speakers and these recreate sounds accurately, on all frequencies. 

They are also good at producing a professional sound because they don’t distort it. As mentioned earlier, this will make what you play on your keyboard sound much better.

So, a keyboard amp is definitely valuable if you’re serious about producing music.

By far, one of the biggest benefits of a keyboard amp is that it can help to create crystal-clear sound, which is a huge advantage if you’re producing music in the studio.

Conclusion

It’s not always easy to know what keyboard amp to purchase. 

But that’s why it’s good to consider if you want one that uses power or can run on batteries like the Roland 4-Channel Stereo Mixing Keyboard Amplifier. 

In addition, you’ll need to think about how many channels you want and what other extra features you could benefit from. 

Some keyboard amps really do come with lots of nice frills that serious musicians might really enjoy using. 

For the less serious musician, these might not be that useful, so a keyboard amp with lower power and fewer channels can be good enough.

As can be seen in this keyboard amp buying guide, there are many different features that can make using the amp much more comfortable, such as when it comes to carry handles; as well as more professional, such as when it comes to what effects it can produce. 

An example would be a piano amplifier. The choice is yours, but it’s always better to focus on what you really need so that the extra features don’t go to waste.

In this buying guide, we’ve covered five of the best keyboard amps on the market that are worth considering if you’re keen on purchasing one. 

Some have all the frills, while others are solid, decent items that get the job done without breaking your pocket. 

In fact, there are many keyboard amps that are both budget-friendly while still offering you a professional product. 

With those, you can’t really go wrong, whether you’re a serious musician or not.
