I'm a doubler, although not usually on the same gig. I play in 5 bands across all genres, from jazz to americarna, rock n roll to soul and ska. Because of my bad back I am downsizing my rig and I have two 450watt 1x12 cabs which are compact and light. I am trying to decide between a GK MB500 (which I already have), an EA Micro, a Mesa Subway D-800, a Tecamp Puma 900, or Magellan 800.Other than the Subway, I don't have access to try any out. Any thoughts, comments?
