Small Amp with Big Features

Ever run into a gig where your playing area is too small for everyone to bring amps, or even too small for a full blown PA? The Behringer Ultratone K450FX is a 3-channel, 45W all-in-one solution. A single 10" woofer gives you full spectrum range to cover everything from bass to keys, guitars and vocals. A built-in feedback protection system will save your ears and keep the crowd happy too. Sculpt your sound with the 5-band EQ and onboard effects. The K450FX also works as a great keyboard amp with its three stereo inputs.

Great multi tool

Keyboard, guitar or vocals all works fine for mp-mf but any louder and you're gonna need a bigger boat. For the $, this fit my use well giving my Alesis more throat.

Great sound at an affordable price

I have used mostly Yamaha speakers and amplifiers over the past 25 years for my personal needs. A few years ago when I discovered Sweetwater I also discovered Behringer products. At that time I was on a tight budget and decided to try out Behringer mixers, studio monitors and effect processors. I was extremely impressed with the quality and performance at such an affordable price.

I bought this amp because I can use it in different ways. It can be used as a traditional keyboard amp or as a playback speaker from my mixing console. It has a warm sound to it and the built in EQ per channel bring out a nice crisp high end. Take my word for it....Behringer makes quality products and they think out of the box....like musicians would. I recommend this amp and all Behringer products to the home musician or enthusiast.

Ultratone K450FX

I have to submit an updated review of this unit now that I have actually learned to use it....the more I work with it the better I like it...it's a very versatile amp, and I suspect that as I progress with it, I'll discover even more of it's virtues...all in all, I'm very pleased with it....5stars...thanks again Behringer and Sweetwater...

Nice Amp | Works as advertised

We've had this for a few months now. Does everything it's supposed to do and does it well. We've been using ours for keyboards, Acoustic Guitar and Electric Drums.

The only issue for me is the covering they used, it picks up pet hair and pretty much everything else.
I've discovered that a Fender Blues Jr. Cover fits nicely on this amp and goes a long way to keeping this amp presentable.

Very pleased with this amp I previously had one for years but gave away to nephew so needed another. Great sound no problems I'm sorry that I bought 2 amps on Amazon that were nothing but problems should have gone to Sweetwater in the first place
