This amp for the money can't be beat. I bought this amp to replace my big heavy kc 500 that weighs in at 70 pounds. Well when I pluged this amp in I could not belive the sound It sounds better than my roland and weighs about 30 pounds less. Oh and cost about $400 less. My use for this amp is a stage monitor. Behringer keep up the good work.

I've had this amp a few months - using it infrequently at 40% volume or less. I'm getting buzzing and distortion. The amp cut in and out during a low volume gig. Not happy. Options are to junk it or? GC? No service little concern. Too bad I hadn't read the negative reviews from people who experienced similar problems with this line before buying.

The amp sounds great. It's not extremely powerful, but an amp stand helps it considerably. It's also very portable.

Amp defective although seldom used!

By Pat Botti

from MA

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

I bought this amp in 2008. I used it maybe forty-fifty times in the past four years and never for more than an hour and at a low volume. FX sounds were never very good and reverb was not that great either, but for the price, I did not have to complain. The sound was clear without distortion. However, a month ago, turning on the unit, I got an enormous cracking noise along with white noise, typical of a power transistor shot.... Something bad in any case. No sound coming through except that horrendous cracking noise. Maybe a power surge on my electrical system? But the amp is usually disconnected from the power surge outlet unless I use it. That kind of problem should never happen on a unit that was barely used and not that old. Now it looks like the repair may cost as much as a new unit. Not very happy with the experience as it died on me just when I needed it.

My 2nd K900FX

By James McLendon

from Killeen, Texas

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

I am a church musician. I have had this amp about 2 years. I just bought the second one so that I could have a right and left channel for my Yamaha P-155 Digital Piano. This new amp works just as great as the one I have had 2 years. I sometimes use one to add a voice mic, but I don't let any other instruments hook up to the amps. I would recommend this amp if you are looking for a good keyboard/vocal amp.

After One Year "Pick Your Poisen"

By Jahzy

from Portage Indiana

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

I purchased one of these small amps approximately fourteen months ago. Initially, I was impressed with the cost effective amp's sound quality and portability. Since the amp was smaller, I only played the sound at 75% or less. After being so careful with this amp, it later began to pop/crack. The warranties only covered one year. After one year, you are pretty much on your own about getting the amp fixed. The reps from the guitar center pretty much told me that they could not help by recommending any repair shops because they did not know of any. They suggested that I simply "google it"(I don't know, but that's common sense to me too). Behringer representatives were very nice, but told me that there were not many behringer certified shops in the USA. Now, I am stuck with a amp that I have to send hundreds of miles in order to get it fixed. It will cost me just as much to send it, as it will to buy a new one. "Pick Your Poison" Jahzy

Good amp, problem with great results

By Bob

from Baton Rouge, La.

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

I purchased this amp for my Keyboard and Vocal. The sound was great on the Keyboard and Vocal. The amp had plenty of volume with a good clean sound. I enjoyed the amp for about 4 weeks then I would get an ocasional pop at full volume. Then the pops got more frequent until a buzz started. The amp still worked fine but the ocasional noises would make people jump. I took the amp back to Guitar Center. No Problem they said. Gave me a new amp and sent me on my way. I have had no problems with the new amp and I enjoy it most every day. Just what I was looking for.

Lasted less than 30 days

By Terry

from Illinois

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

The amp had a great sound at first. I cranked it 3/4 volume with my electronic drums and it blew out the base circuit or speaker. Now, every time I hit the base drum, it pops and crackles. I'm exchanging it towards a Roland.

This thing is sweet

By Owner of this device

from In my house

Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

This amp is great for vocals. when I got this amp I wasn't sure if it would be heard over a drum set. I have the amp at half its capable volume and it can be heard over drums, guitar, and a bass. We like to play loud too.
