Top 8 Best Keyboard Amps 2020 (With Buying Guide)

A keyboard amp is an essential piece of equipment for every keyboard player. A good amp can significantly improve your sound and allow you to expose your full potential as a musician. Keyboard players often like to carry their own amp at live gigs, instead of connecting directly into the venue’s PA system. Choosing the right amp to buy is quite important, as a keyboard amp is something that you usually have to buy once: most of the times it will take a few years until you decide to change or upgrade it.

Deciding on the right amp for you might prove to be a daunting task: hundreds of models are available on the market and sometimes it is quite hard to understand which features are responsible for the various price tags. Spotting the differences between the amps is also difficult if you are not familiar with the specifications.

Best Keyboard Amps –  Buying Guide

Keyboard amps are essential for keyboard players, as they help to amplify the instrument’s sound, as well as control it through equalizers and effects. Such an amp can be quite a big investment for a musician and consequently the choice of the right product is crucial. There are many specifications that make each amp different and suitable or not for you needs. To help you choose the right amp, you can find below a buying guide that explains thoroughly all the things that you should be aware of before buying a brand new keyboard amp.

Sound quality

Sound quality should always be the most determining factor in choosing the right amp for you. There is no point in getting an amp that won’t give you crystal clear audio! That means that you should check whether the frequency spectrum covers your needs, as well as if the volume output is adequate for the space where you plan to use the amp. Some amps deliver mono sound, while others produce stereo sound performance. Depending on your budget, you might want to look for even more advanced sound qualities, such as amps that can emulate the sound performance of a tube amp.

Number of channels

The number of channels that each amp supports determines how many different instruments or microphones you can connect to the amp. In most cases, each channel comes with separate volume and effects controls for better personalization. This can be particularly useful if you want to sing while playing, or if you enjoy playing with other people in small spaces. Note that the more channels the more expensive the amp, so if you just need to plug in a single instrument, there is no need to get a multi-channel one.

Portability

If you need your amp only to practice at home, you can skip this category and move to the next right away. On the other hand, if you plan to carry your amp around for rehearsals and live gigs, it is crucial that you get an amp that is pretty compact and as lightweight as possible. Some keyboard amps have been designed for portability and might even include a handle for easier transportation. If you are also planning to play on the street, don’t forget that you might need a battery-powered amp.

Inputs and outputs

Not all buyers realize that besides the number of channels, the variety of inputs and outputs of an amp is also important. Other than the classic instrument inputs, XLR inputs let you connect microphones, while RCA inputs allow you to connect devices such as CD and MP3 players (even your smart device with the right adapter). The right outputs will allow you to connect the amp to an external PA system, a very useful feature for live performances. Finally, headphone outputs let you practice quietly, without disturbing everyone in the house.

Budget

It is true that keyboard amps come in a great variety of price tags. There are many budget-friendly options for beginners that will certainly do the job, but if you are an advanced keyboard player, it is better to pay a little more and get an amp that won’t be useless for you after a couple of years. A keyboard amp is something that you should buy very few times in your lifetime, so make sure that the one you will get satisfies both your current and your future needs.

Built-in effects

Many keyboard amps nowadays come with built-in DSP (digital signal processing) and incorporated effects. This feature can save you a lot of money that you would otherwise invest in effects units and pedals. These effects usually include reverb, chorus and overdrive, but they might also incorporate more complex effects, depending on the amp.  There are also amps with feedback protection system (useful for monitoring when playing live) and with built-in graphic equalizer that lets you fine-tune your sound performance. Note that these effects might increase the price of the amp, so you might want to exclude this feature if you are tight on the budget.

Power

Speaking of power, I mean both the power to operate the amp, and its volume output. The first is quite important if you want to carry the amp in places where there are no AC outlets. There are quite a lot of battery-powered amps on the market with different options such as AA batteries or rechargeable ones. However, if you don’t plan to use this feature, it is better to get one with that connects to the usual AC power outlet. That will also give you greater volume output, a feature that you should pay attention to if you want to fill large spaces with the sound of your keyboard.

Other features

There are several other features of the keyboard amps that don’t fall in any of the previously mentioned categories. For some people, robust build quality is a must, and I would certainly advise you to pay attention at that especially if you are looking for an amp that you will carry around a lot. Don’t forget that build quality also adds to the overall durability. Finally, it is true that some amps are more elegant than others, so if the looks are important to you, you might want to check that out, too.

As you have probably already realized, there are many keyboard amps out there with very different specifications. The amp that you plan to get doesn’t have to meet all the previously mentioned criteria, but it should certainly satisfy all your present and future needs. So, before you decide on the model you wish to purchase, take a moment to think about what you are planning to use this amp for. If you think that more channels or built-in effects will be useful to you in the future, it is better to spend some extra bucks now and invest on your keyboard amp. I hope that this guide has helped you choose the right amp for you!

Final Words

While all the amps that have been mentioned previously are top-of-the-line, there are many factors that can help you pick one of them to buy. Your budget is always important, as they come in a variety of price tags. However, what you plan to do with your amp is equally important to define your choice.

If you plan to carry your amp around, try looking for lightweight amps. Sometimes, those that are battery-powered can allow you to play everywhere, without worrying about power outlets. On the other hand, amps that have been designed for portability sometimes lack in sound quality. In case audio quality is a priority for you, take a look at the frequency response of the amp you intend to buy. Finally, if you are planning to connect other instruments in the amp, you should probably purchase one with an adequate number of channels (at least three, as some might require stereo inputs). Remember that microphones need XLR inputs, unless you have adapters lying around.

Whatever your choice might be, a keyboard amplifier will significantly improve your sound, allowing you to focus on your musical progress. I hope that this list helped you pick one and start playing!
