I love mine. Best solid state combo I've ever played through. Simple controls, no frills, great vintage tone. I've had it a little over a year - no problems. Not too heavy, I do suggest casters though. Seems well constructed. It has quickly turned into my main gigging amp for small shows (which is about all I play anymore.)It mics/records really nice.
Ricks sound EXCEPTIONALLY good through it.
No tweeter or XLR out, but they're introducing a B200R that has a tube preamp, tweeter & XLR out supposedly this month.
I use mine exclusively for guitar and I love it. Loud with just enough edge for our alt-country band. Although for bass (which it is intended for), I found it wasn't loud enough (clean) to keep up with our drummer.
For what it’s worth, when I was shopping around, it was the best (warmest) sounding combo amp I tried. I wound up eventually getting a separate head (Ampeg) and cabs (Ashdown and Avatar). [Look ma, all “A’s!”]
On gigs where the $$$ is low, in order not to spend it all on crew, we cut corners and don't have the backline brought from storage, set up, etc. We bring amps from home. I bring my Ampeg combo. It works/sounds great, but would be better with an XLR out. I get around this by using a SansAmp Bass Driver DI.

I like these Ampegs. A guy uses one at a local blues jam I go to and has a Harmony semi-hollow bass with flats that has bottom for days on end. If I plug the RIC in afterwards, I have to turn the bass way up to get anywhere close to the bottom his bass has. But the amp sound snice with just about everything through it.
