I came across a posting today selling a Markbass rig as follows: CMD 102P (600W w/ 2 10 inch speakers) coupled with a Traveler 151P (15" 400W cab) for $775. It gave me gas but I am having some second thoughts and would like some opinions. I currently have a Genz Benz Shuttle 6.2 (600W) that is a combo with 2 12" speakers with smaller twitter speakers in each of the two cabs. Although the MB is certainly more in terms of speakers including the big 15" cab; the GB has a tube pre-amp which provides a lot of versatility in sounds. I would think I could sell my GB rig for something close to the cost of the MB rig. Would appreciate thoughts (pros/cons) and opinions. Thanks DJ
