I bought the K900FX to use as a small PA system when playing at smaller venues when the full setup was too much. I had tried acoustic amps, but the ones I tried didn't do so well on the vocals. I run my acoustic/electric guitar through channel 2, vocals through channel 1 with a little reverb from the on board effects, and cd backing tracks of drums, bass and additional guitar parts (previously recorded in my home studio) through the CD input. This still leaves one additional input for guitar, bass, keyboard, etc. The 5 band graphic eq makes the right sound easily attainable. Set flat, it's a little heavy on the bass. The built in stand socket allows me to mount it up off the floor on a speaker stand to fill fairly large rooms (150+ seat restaurant last week) with very clear, rich sound. I've used this PA for three months and have found it easy to transport and set up and it seems to be built tough enough to withstand the road.

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.

      Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

      Two line-level inputs, One Line-level / XLR Mic input. Onboard effects. Nice sound.

      I like the fact that the control knobs are on the top, not the front -- it's a lot easier to get to them no matter where you are in relation to the amp.

      The one drawback is that it is a bit heavy, but it needs to be to get the sound quality that it provides.

      Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

      I bought this amp to use with a classical guitar that also had synth access and absolutely love the clear sound. After trying it with this guitar I decided to try my avoustic electric and semi-hollw jazz guitar and it handled all with equal clarity and great tone. I am using this primarily as a practice amp but could see it as a good amp for small venues.

        A great amp in every way except that it is not big on volume. It does get loud enough for home practice or maybe miking a guitar in a coffee house or for amplifying speech like in a school function. But for a band practicing or performing it won't be good. I wish I had gotten the next model or two up from this one. But for little jobs its ok.

        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.

        It works just fine for guitar, and everything else...

        By Charlie Charlie

        from Portland, OR

        Comments about Behringer ULTRATONE K900FX Keyboard Amp/PA System:

        It's good
        Before buying this amp I had read a review on here stating that you shouldn't play an acoustic guitar through a keyboard amp because it will be too quiet. I would like to set the record straight: it works great for my acoustic guitar!

        I ran a mic and my guitar at the same time. I was very pleased. My understanding is that each channel is 30 watts, so no, it's not going to sound like 90 watts when you're plugged in to one channel. but it's still a very good volume. Keyboard amps can handle a lot of different instruments, INCLUDING acoustic guitar.
        I bought mine used, so I don't know if it's an issue of quality or abuse. Either way, the effects don't work right. There's a lot of crackling and popping constantly when they are on. So I turn the effects all the way down. Everything else works great, and it was only $125 used, so I really can't complain.
        It works great. It's relatively light (40 lbs). 3 inputs. Does everything I need it to...
