I know its a polarizing brand here on TB, but I've been gigging a Markbass 1x12 for years now. In small places it holds its own. Medium to large venues it works well as a stage monitor. I like the way it sounds, but then I play clean and want the character of my basses to come through without much color from the amp. Here it is a a wide variety of venues:
Tiny place (actually an ice cream shop, really fun local spot to play and pay is equivalent to local bars

)

It worked great on all of em. The DI is clean and quiet, with output level adjustment. 4 band EQ plus mid scoop and high end roll off. I think it weights just shy of 30 lbs.
