Feature:
Very flexible mixer section. I do a variety of gigs and it fits into every situation. Addition of reverb and a mic channel make it perfect for small one-man band/DJ gigs. If I need more sound it will handle two additional speakers with no power drop. I sometimes use it with 12" PA speaker on a stand and a spot monitor on my keyboard. For my blues band where I do a Hammond B3 simualtion w/bass pedals (Roland VK7) and digital piano, I use the stereo outs into my PA. Fills the stage area with sound nicely and the PA spreads the keys around the room. I've even used it as a small sub with my PA for DJ gigs. The EQ works very well and will cut out all the mids and highs. Don't need a separate low pass filter or crossover.

Quality:
Very solid and well made. Nice clean looks. I wish they offerd a cover for it as the controls are on the top. I will have one made very soon. I've used a bunch of Crate stuff for a lot of gigs and have never had a problem. 5 year warranty is nice to have if needed.

Value:
At first it may seem more expensive than some others but if you look at all the features it's worth it. It does the job well and makes my gigs easier so it's a plus. I'm glad I did my research and choose this amp. More compact and flexible and kicks as well as the Roland or Peavy's.

Desirability:
This amp has a nice clean look, is very flexible, compact and well built. I am seriously considering a second one.

Sound:
Very loud, clean and uncolored sound. Plenty of DB's for most applications. If you are with an extremly loud band use the stereo outs and go into the PA or house system.

Support:
I've called with some questions on other products and always have gotten the info I needed. Sometimes hard to reach but they will help you. Never had to use the warranty for any of their products and I've owned three power mixers and three sets of their speakers. Blown one horn driver in all the gigs I've done with the stuff. Replaced it myself. All of the repair shops near me support them so if I have a problem I won't have to go far to get it fixed.

Overall:
You can't go wrong with this amp. It does everything and more that you would expect from a keyboard amp. After mine arrived at the store a church musician saw it and bought two for his digital piano.
