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.
In order to assist you with this task, I have gathered for you the 8 top keyboard amps on the market right now. Each one of them comes with its pros and cons listed, so that you can choose which one works best for your needs.

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!
