Feature:
Long enough cord, nice and sturdy. Able to plug in a guitar or even vocals with the right cord. Very versatile.

Quality:
No one beats roland sound. Very sturdy. Might want to have some more watts jsut in case, but if this is the power you need, you are set. You will never need another amp. I'm buying a bigger one because 60 watts just doesnt cut it anymore.

Value:
I wish i could be cheap but if you can afford it, buy it.

Desirability:
AMAZING, wish it could be louder... but thats why you buy a bigger amp.

Sound:
Fantastic sound... roland is the best. Very good bass response, and a two button equalizer if you don't have enough of the high you want. Very easy to get the sound you want. Not just for keyboard, but highly recomended, you can do vocals, guitars and bass too.

Ease of Use:
Plug and play. Within minutes you'll be a master of this amp.

Support:
I guess if i never needed to get support, it is excellent.

Overall:
I thought i would never have to replace it but i did because it just wasnt loud enough.

Feature:
Standard, 4 channels input, all stereo with channel one having a mic in port. I haven't really played it much with more than one instrument through it, so I cant tell you how it handles all 4 channels being used. It also has a nice support (which I havent used) to pair up two of these amps for stereo sound. Unfortunately, it doesn't have built in reverb / chorus.

Quality:
This is one sturdy piece of equipment, built like a tank, built to last.

Value:
Other than that boomy bass, its a great amp.

Sound:
I use this amp for my Yamaha piano, and it does sound really good, except the low end is really boomy. Even with the on board EQ bass turned all the way down, its still got this 'boom' to it, I can't understand why you would need a subwoofer with it.

Feature:
For dumb drummers like myself, simplicity is everything and this little amp fits the bill. Also the small footprint is just what I need in my small studio.

Quality:
It looks fine as far as amps go.

Value:
Worth what I paid.

Sound:
I'm using this product for my V-Drums. Fantastic sound from the lowest kick drum to the highest high-hat and crash.

Ease of Use:
Like I said...Simple. I was hittin it hard in 5 minutes after taking it out of the box.

Support:
No experience with Roland service. Nothing has broken.

Feature:
There are plenty of inputs and volume controls. This amp removes the need for a separate mixer.

Quality:
Very tough and solid with quality components.

Value:
Reasonable price for this quality and level of functionality

Desirability:
It's hard to get excited about the sex appeal of a keyboard amp, but as such things go, I guess it's OK.

Sound:
I run two of these amps as a stereo pair combined with the matched subwoofer. I play a Korg Triton Pro-X and Roland Fantom X6. The sound is outstanding, very clear, with an enormous dynamic range. It really showcases the sound-generating capabilities of these fine synths.

Support:
(Haven't used)

Overall:
I don't ofresee ever needing another keyboard amp.

Quality:
This product is very luggable and sturdy.

Value:
It costs a bit more but represents premium value.

Desirability:
Unless you want the '60's stack of amp looks this is the perfect size and power. I placed it on a spare stand and it functions great off the ground.

Sound:
I love this amplifier and you will too!

Ease of Use:
I set the knobs and turned it on. No hum, no issues, just great sound!

Support:
Support seems fine - not that you are likely to need it.

Overall:
I am set on amplifiers!

Feature:
It has plenty of inputs, one of my deciding factors on purchase. I prefer to send my guitar signal through a balanced line and this is one of the few amps that has an xlr input.

Quality:
Very high quality. I also have a KC550 and am totally amazed at the lack of noise. Plug it in with no input, crank it to eleven, you won't hear ANYTHING! If you plug anything in and get background noise, check your gear.

Value:
It's a bit pricey, but the quality is definitely there.

Desirability:
Good looking amp. Looks like it means business without a lot of flash. The blue speakerboard sets it apart also.

Sound:
I use this amp for my guitar. I have a Taylor and the expression system just sounds better through a full-range keyboard amp than through any guitar amp.

Ease of Use:
Plug and Go!

Support:
Don't know. Never Broke

Overall:
I know its a Keyboard amp, but just a little DSP would have been nice (reverb/chorus/phase)
