Bought a gk 800rb after years of using them as backline on large stages. For local gigs its been enough power for most anything I do. Thinking about a mesa walkabout. Its rated the same power as the 800rb. BUT!!! Every thread I read talks about the walkabout for rehersals or small gigs. When I called the factory, they were very carefull with a response about power. What up? Does the walkabout have as much uummph as the 800rb?
