Feature:
A cover would have been a nice option for when it's raining out.

Quality:
Built like a very high end unit.

Value:
I tried Roland amps, every model, several years ago, and they ALL rattled (was told this was "normal!") and the cheapest one cost nearly twice the $. The sound was also inferior. This amp is EASILY the best keyboard amp buy I have seen. (OK, it does come with a giant sucking sound, if you know what I mean.)

Desirability:
Excellent compact design, feels extremely solid and is good looking.

Sound:
Great sound. Buy two, and you could have a respectable home stereo when you aren't using them for gigs.

Ease of Use:
It better be easy to get good sound, as the "manual" is an example of stretching the term to the breaking point.

Support:
Called Behringer with several questions and the guy didn't seem very knowledgeable at all. He did say that phantom power would take care of the mic level issue, but no explanation on why this is pretty much unusable without it.

Overall:
I

Feature:
The EQ has a very effective setup for the rooms that I play in.For such a little amp it does pack a punch.I like the fact that I can go to a gig with just that amp and do everything with my mic.,my keyboard and my midi setup.

Quality:
This amp seems well made to me.I wouldn't be afraid to use it on the road.It would be nice to have a dust cover for it though.

Value:
Best bang for the buck!!

Desirability:
Nice looking well made unit

Sound:
The amp has everything that I need to play the gigs that I do.It has the Roland amps beat hands down.I don't need the effects as much as I thought that I would for my keyboard, but they are very nice for the acoustic guitar that I play on my Saturday afternoon gigs.

Ease of Use:
The manual gave a few pointers,for the most part that wasn't even necessary.It was very easy to use out of the box.I had to go online and get the effects data,but that isn't a big deal.

Support:
I have a Behringer eq module that I have been using for years.I had to get some information on how to use the real time analyzer once and they were very helpful in telling me how to get the best out of the module in a noisy room.Never needed any service on this product.

Overall:
Don't think that I will be needing another amp for my purposes

Feature:
all the competition has and more with built in effects to be a inclusive package.

Quality:
appearance seems to match that of a Rxxxx kba and lacks a luggage rack style carring device with wheels like the Pxxxy kba,.

Value:
Not a pocket drainer and price was the main concideration for keeping me out of trouble with the little woman.

Desirability:
Its the coolest looking keyboard amp on the market and if it proforms half as well I will be one happy pianoest.

Sound:
I have high expectations concering the specification and design I know they added new keyboards to their line so they went and built a rugged and effective stage amp.

Ease of Use:
expect some learning curve here i currently find a manuel on this amp? what gives with that?

Support:
dame cheep in price and if it broke I would buy another. the company as far as I know is some what inexcessable and outside of USA>

Overall:
I have had a bass amp for 5 years and still no problem I donot abuse and travel extensively yet do local giging and jaming so it has held up nicely. still the name has no repetation with the local gentry.

Feature:
7-band EQ is better than the bass & treble knobs. Sub out feature is handy.

Quality:
Keeps on truckin!

Value:
Such a bargain. It is half the Price of a Traynor and a Peavey

Sound:
Crystal clear with alot of headroom

Support:
None needed

Overall:
Great for gigs. This was a loaner amp because my Peavey was stolen. In between sets, we hooked up an IPOD and everything was awesome. No complaints.

Feature:
There are 4 stereo inputs, one of these also has a microphone input with it - pretty good for a multi-keyboard set-up. It has a headphone output with it's own independant volume that doesn't cut off the main speakers when you plug in a set of headphones. It has a stereo "line in" that can be used to connect and play your iPod or CD player through. The graphic equalizer if OK - it does as good a job as a three knob (treble-mid-bass) system. It also has a stero link that is supposed to connect to another amp and get true stereo - but I haven't tried doing that since I only have one of these amps. It claims to have 100 digital effects - well, technically it does but they count every different intensity of tremelo as one of the effects. This means that there are really only a handful of effects (Tremelo, Chorus, Phaser and some combinations like Chorus+Phaser. The effects aren't bad but I don't have much use for them. Missing from the effects is a decent "Rotory" spin

Quality:
For the price this little baby is great. I've listened to it side by side with comparable Roland and Pevey keyboard amps. The Behringer sounded MUCH better than the slightly higher priced Pevey. It sounded a little better (particularly at high volume) than the Roland which cost twice as much. Personally, if I wanted to spend $500 on a keyboard amp, I'd buy 2 of these over the one Roland, any day.

Value:
This is a great keyboard amp for the price. There are better amps out there but they cost at least 3 times as much as this one. This is one of the best keyboard amps under $500 US - and it actually lists for only $250 US.

Desirability:
I'd certainly buy it again if this one broke. I'm seriously considering buying a second to get true stereo. Looks-wise, Behrenger, Roland, and Pevey all look pretty much like the same stubby black keyboard amp

Sound:
The overall sound is very good. It tends to be a little bassy but that can be adjusted with the on-board graphic equalizer. The sound is clean even when playing at full volume. One possible drawback is that at full volume it produces a noticable hiss when it's sitting idle. Great amp/PA for a solo performer in a smaller venue. Acceptable for a keyboard playing in a (rock) band at a smallish club.

Ease of Use:
It's a pretty standard 4 channel amp. Not very difficult to use.

Support:
I haven't needed to contact Behringer about anything so I really can't say much about their support. The users manual is a little slim and wanting. The list of digital effects is not in the manual and must be obtained online.

Overall:
I've had this amp for 4 months. No Problems. Use it LOUD as my keyboard amp to gig with a rock band. Use it as a 4 channel PA with a guitar player for "coffee house" kind of set-up (piano, electro-acoustic guitar, 2 mic'd voices). It's a great general purpose keyboard amp.

Value:
For $50 more, I could have purchased the larger 300watt model, but I like this because it is more portable and I don't play large rooms anyway.

Sound:
Warm and rich

Feature:
Features look great, too bad the sound is not flat.

Quality:
Pretty well built, but see above.

Value:
Need a lousy sounding amp for a low price, this is it.

Desirability:
Have it and regret I do.

Sound:
This is the worst of all. I run a triton and a fantom thru it. It just sounds terrible. No matter what I do with the eq it does not change the fact that this amp does not sound good, which is the ultimate justification for buying an amp. I a/b it with the roland 350 (which too has its faults) and there is no comparison. Too bad, considering the specs...

Ease of Use:
uh duh

Support:
never tried...

Overall:
I've owned this amp for about 6 months. I work a lot in the nyc area. It was light, specs looked good, price was a gamble. oh well... I do not recommend this amp to the discerning ear.

Feature:
The bells and whistles on the amp are good.

Quality:
The amp is a new amp. I am taking it in for warranty service, in case there is a problem internally causing it to lack power. Although, I have read from reviewers on other sites that they also thought it lacked power.

Value:
If the amp were advertised at 60 watts not 180 watts, then you would know what you are getting.

Sound:
The sound is clear and bright compared to my Roland KC 350. However, the KF1800 has no power. When I take it out on a gig, I have to play it at 3/4 volume and at some points it is not even effective as a monitor. If I try to get it any louder it breaks up. If you are going to use it with a medium to loud volume band forget it, unless your keyboard has a really high output volume. It has half the power of my Roland although the Roland is only rated at 120 watts.

Support:
Support seems to be responsive so far. However, if they overrated the power of the amp, there is nothing support can do about it.

Overall:
I chose this product for the power ratings, its options such as eq and effects, and light weight. Unfortunately, its lack of power may require that I replace it sooner than later.

Feature:
Good features...Fx capable

Quality:
I was warned about purchasing a Behringer amp...The word is that they blow up under preasure. I purchased several Behringer outboard products in the past and were satisfied with them. Therefore, i figured those warnings were subjective. WRONG!!! I took my "Brand New" Ultratone K1800-Fx out on a gig yesterday, however, 20 minutes into my performance the amp started making a horrible buzzing and crackling noise. I had to keep shutting it on and off...eventually i could not continue with an auditorium filled with people gathered for a birthday party. I was performing solo using backing tracks played through my laptop, Vocal mic and my acoustic guitar. I am now embarrased and humiliated for spoiling what had started out being a fun party. My confidence is "shot" when it comes to risking using another Behringer amp.

Value:
Could have been great if the unit held up.

Sound:
The sound was fine...however...

Ease of Use:
easy to use (after reading the manual and becoming familiar with the channel buttons).

Support:
At this time I'm awaiting a response from Behringer!

Overall:
...See my Quality entry.
