Feature:
More channels would be welcome.

Quality:
It's Peavey. That means built like a tank. I threw it several times in the back of my car, i guess it can withstand most normal or even less-than-normal shocks. It can be used both at home and on stage.

Value:
For this money, it's OK.

Sound:
I have an Access Virus TI synthesizer and a Roland RD-700GX stage piano. For sounds like those generated by a stage piano or a usual home keyboard, the KB-2 is more than OK, but the Virus TI can generate extremely complex sounds that this amp cannot always render. Anyway, it sounds with personality, sound depth is +++++. I wouldn't recommend it for someone looking for spatial / electronic / new age music, Jarre-type effects and so on, but for general playing, i'd say it's at least 9 out of 10.

Ease of Use:
Just plug it in the mains, connect your cables and switch it on. Well, if someone has some technical problems concerning these things....Manual ? You don't need it.

Support:
Never needed one.

Overall:
If i had to replace it, i'd go for the same thing.
