I have had some bad experiences with a few different Behringer amps over the last 10 years, so I really don’t purchase them anymore. But in a certain situation I didn’t have a choice but to use the Behringer Ultratone K900FX. It is a 90 watt 3 channel amp that can be used for your keyboard. The sub is 12” and the tweeter is only 1”. The price of this amp was the only reason I used it because I needed a quick cheap amp when I was in a tight spot so this was the one that I grabbed from GC earlier this year. I was actually surprised with how good it sounded and having the FX on board was a huge bonus because I didn’t expect that. The Behringer Ultratone has an XLR input, a Auxiliary input and a headphone output. For it to be a cheaper amp, it sure does weight a lot more than some of the other amps that I have used that cost more. It weighs 40 pounds and can be mounted to a pole for performances.


I really enjoyed the way the Ultratone sounded with my keyboards and our guitar player used it as well for a short period of time. I was very pleased with the sound that it gave me for 250 dollars. Though we did not keep this amp that long, I do recommend it to someone who does not have a lot of money to spend on an higher end amp. It is very well built for it to only cost that much and has a very clear sound when turned up to the max volume.


If I every needed a quick buy again to have an amp for a performance and didn’t have the money on hand to purchase a higher end model I would purchase the Behringer Ultratone K900FX again without a doubt. Behringer outdid there self on this one, I didn’t not expect this kind of quality out of such a low priced amp from them.
