Feature:
The 4 lines in with controls is my favorite feature plus tape in and out.

Quality:
Sounds good, built good,

Value:
I got this baby over a year ago for todays price and it performs well in every situation where I use it

Desirability:
This baby is sexy, all the controls on the front.

Sound:
Great sound, sound quality I was looking for. I get the sound I was looking for and more. In every setting I have used this amp it kicks but (practice, on stage, in the park, in the mall). I use a Kawia K4, Korg c505 concert piano, Yamaha psr172. I plug my tape deck/cd into this amp and play/sample/record all at once. I do not turn the volumes to max, and I try to only have one instrument plugged in at time during gigs.

Support:
No need for support thus far

Overall:
As it looks right now this amp will be with us for a long time due to it's versatility and ease of use.

Feature:
Like all the features . Very nice. Use it mostly for input from a Theremin and it is great for that. 3 octaves above and 2 below middle c.

Quality:
seems to be on par quality wise with everything else out there and costs less.

Value:
far cheaper than other products of same kind.

Sound:
Havent had it long enough to move it around a lot and test it for different enviroments.

Support:
Have other products from this company. They all work as advertised. No reason to contact them so far.

Overall:
I expect to be satisfied with this product for a long time. It's the best thing out there for the money. The only drawback is that the amp doesn't come with casters.

Feature:
Cool direct out slot, fx inputs and yadada. Never used it other than to play back recordings from the jams which were just recorded and to amplify my keyboard.

Quality:
Overall, less than 2 years of use. Owned it for 2 2/5th's year, quality began to decrease mid 06'.

Value:
If you are careful with it and keep the volume to a reasonable level and direct out to a pa for louder amplification I am sure this amp would last a while.

Desirability:
It is a black box with a few nobs. It is heavy. Youch.

Sound:
I purchased this product in Early 2005, as my first Keyboard Amp. Sounded great, real loud, projected the Organ, Piano & Synth sounds of my Casio WK-3500 very well for about 6 months, and then my usage of this product slowed down dramatically. Started up again early 2006, no real problems then either, still very loud tones, would crank it to compete with the guitar, bass and drums. But mid 06' I began to notice a decrease in volume presence and a slight crackle and lack of power.. the 15in speaker/woofer blew out in April of this year. Right now it sounds horrible. Sounded great for about a year. Sounded like noise coming from a big black box, rather than the instrument itself.. know what i mean?

Ease of Use:
Was very easy, plug in the power cable, plug in your instrument, turn on, adjust volume and eq.

Support:
Never needed any.

Overall:
If you are a keyboardist, invest in a quality PA system. I purchased two Peavey PR 12's (will be exchanging them for PR 15's for more low end) and a Soundcraft Gigrac Powered Amp/Mixer. You will be much more satisfied. Not a bad purchase for your first amplifier, but do some research and decide for yourself.

Desirability:
Would never buy it again. If you only want organ or bass sounds it would be OK. For any type of stereo piano sounds, it is awful, it sounds either very tinny or if you eq to bass very muffled.

Sound:
This amp is OK for organ sounds and even for a bass guitar. It sounds terrible when used with a stereo keyboard using piano or pad sounds. My moderately priced headphones sound much better reproducing piano sounds than this amp.

Sound:
I use this amp for a Yamaha Electronic kit. Works great, sounds good, but not in louder venues. drummer harry

Feature:
the four input jacks are great, you can even use it as a mixer if you wanted. the fine tuning in the sound was great before it blew on me, and now whatever i do it still sounds terrible

Quality:
i can't even talk about the quality....instead i'll sum it up in one word....HORRIBLE. don't be fooled like i was and think that all the other reviews for this product out number this bad one. i'm not lying don't buy this

Value:
it's a good price for what you get i guess

Desirability:
no not really...it doesn't look very cool at all. its just a big black box

Sound:
This amp was great in the beginning when i first bought it. but just about a month later it completely blew on me. now it sounds muffled and far away. i can't stand it so i'm selling it and buying a new roland kc-550.

Support:
N/A

Overall:
i'd say it lasted me about a month before i wanted to kill myself everytime i listen to this thing make a sound
