Clean sound for many purposes

I have this amp for a few months now, and I don't regret getting this one. It's sound is just amazing and it has enough power to get me heard over my band mates (they have a nag to play somewhat loud).
I use the KC 550 with a Yamaha NP-30 and an old PSR-220 for the moment.

Sound:
Great! This amp reproduces the sound as it should. It has a rich bass response, which I like very much about this amp. Though I got to be careful not to drown the bassist sometimes. (Can be solved with the EQ). Vocals sound very good as well. To prevent 'howling' when using a mic, try to lower the High range by about a fifth. In most cases it solves it for me
I've ran a electric guitar trough it a few times, it sounds very clean and almost acoustic.

Versatility:
I like that the KC 550 has four (Stereo) inputs and an extra AUX input, making a total of five inputs. I use it as a monitor and mixer when we record our songs by ourself. The sound output, when all channels are mixed, is very good. A great plus to this amp.
There are casters attached to this unit, which can be taken off. This is a good thing, since it's not that light (~27 kg) and somewhat bulky.
The KC 550 has a Stereo Link ability; you can link it with an extra KC 550/350. Combined you can have ten inputs (eight without AUX), though on two different outputs.
This unit features a three band EQ, which is all I need actually.

Overall:
This amp is great for small to medium-large sized gigs, and has enough power to be heard over the guitars. It does need some tweaking when in larger areas. (I have to give the high-mid range a small boost for better sound.) The four (or five) inputs are good for me, I only use three at the moment.
I'd certainly buy it again if it ever should get stolen.

  GOOD VALUE!!!!!!!!!!!!!

GOOD UNIT FOR THE BUCK! NICE SOUND, THE 4 CHANNELS ARE A PLUS. VOCALS ON CHN.1 INPUT ON PAR WITH A DECENT MIXER. THE POWER CORD SHOULD BE OF THE DETACHABLE TYPE, (IEC), IF YOU PUT A COVER OVER THE UNIT, THE POWER CORD WILL MAKE IT HARD FOR A GOOD FIT. TWO TECHNICAL NOTES, THE SUB OUT IS FULL RANGE, NO INTERNAL CROSSOVER INCORPORATTED. IF YOU DON'T HAVE A PASSIVE CO ON YOUR SUB, YOU WILL NEEED AN ACTIVE CROSSOVER. THE XLR OUT ARE TOO HOT IF YOUR GOING TO A BOARD WITH ALL CHANNELS IN PLAY. HAD TO GET A COUPLE OF ATTENUATORS TO QUELL THE DISTORTION. -10DB DID THE JOB, (BTW) THIS CLIP WAS WITH THE GAIN AT IT'S LOWEST SETTING. ALA AN ALL, A DECENT UNIT, HAVE HAD MANY COMPLIMENTS FROM THE AUDIENCE ON THIS UNIT IN A LIVE SETTING.

  Amazing!

I have been using this amp for about 2 years now, and am still very impressed.

I originally bought this amp to use with my Roland V-drums. And the main reason, is that it had a 15" woofer so I knew it would reproduce the kick drum accurately, whereas the other amps I tried just sounded thin.

Well, it sounded amazing on my V-drums, and really reproduced them very well.

But what is really impressive about this amp is the flexibility. I have used my V-drums with it, my guitar and bass through my PODxt into the KC-550. My iPod sounds amazing through the KC-550. I have actually used it as a standalone DJ rig at a smallish party, and all I had was my iPod, a microphone and my KC-550. It did a great job.

And of course it sounds amazing on keyboards also. I don't have an actual synthesizer, but I have used my Axiom-61 into Reason 3.0 on my PC, and output it into the KC-550 and it sounded really nice.

I have been using it a couple years, and have nothing bad to say about it at all. It continues to impress me.

This amp sound clean and clear. The bass sound is full and punchy. I use the amp with my Motif6 and was blown away by it's amazing sound.
