Behringer Ultratone K450FX 45 Watt 3-Channel Mixing Keyboard Amp
Gearank High Notes
The Ultratone K450FX appeared on our recommended list for Keyboard Amps Under $200 when we first published it in May 2016.
It was the highest rated in that price category in September 2017 through November 2019.
It came off the list after that when it was out-ranked by the Peavy KB 1.
The Behringer Ultratone K450FX is both a keyboard amp and a small PA system with 3 independent stereo channels, an XLR input for a dynamic mic and onboard effects including reverb, delay and more.
Note that it doesn't provide phantom power so you'll need some form of mic preamp like a vocal effects pedal that provides phantom power if you want to use it with a condenser mic instead of a dynamic mic.
It is also designed to be used as an amp for electronic drums, and some acoustic guitarist / singers also use it.
Behringer have also included their FBQ Feedback Detection System which provides a control knob for eliminating feedback at specific frequencies.
The built-in effects are reasonable and add to the value you're getting for the price. One thing to note is that you can't edit the effects, but there are 100 presets to choose from.
If you need a versatile amp with effects then this is a reasonable option.
