Excellent little head, reliable as hell. Owners of these don't get rid of them. They know in 20 years they'll still be kicking out those 700 watts.
It's a great amp for the cost. They are in a lot of people's closets. They aren't a MAIN rig for active gigging musicians usually because of weight and headroom, but they make a great backup. I've never seen one that didn't work.
