I concur with everything stated in the first post...I just took my MB212 out the other day and everything I could say about it is everything the OP said--loud, light, and sounds good.
I had the same setup experience too--i just plugged it into the wall--done! The other guys don't want help setting up, so i went and got a beer
I was a little unsure about using a combo at a gig, as I never owned a gig-able combo in the past so i had no experience with one, and the lack of extension cab jack was a bit worrisome at first but after sound check, I realized that this thing can hold it's own pretty nicely. Of course then logic knocked me in the head saying it's a 500 watt amp paired with a 212 so it actually is a pretty decent gig-worthy combination anyways lol
all-in-all i was really impressed with this thing too!
