The Shuttle 9.0 thread has been going on for some time, and I thought all of us who have the 6.0 should have a place to discuss and complement it. I've changed from a Sunn Coliseum-300 with 70 to 90 pound cabs; now I'm using a Shuttle 6.0 docked on a single 12T, with another 12T that I can connect when needed. The change has been wonderful...and the Sunn is strictly a backup head now. The first time I connected to a Shuttle 6.0 was at a gig put on by a music store - and I darn near blew myself off the stage. I and all the band were amazed at the volume and depth coming out of a single 12" speaker. I finished the gig and told my wife "I know exactly what I want for Christmas - that Shuttle 6.0 and a pair of the 12" speakers". That's what I got, and the heavy cabs were sold within a week. To date, I've only needed the second 12" speaker once - when we played a gig in a horse barn 200 feet long. Even then, I had gain and headroom to burn. It's a fantastic amp and cab setup, and it's something that is bound to attract lots of us boomers who are tired of lugging heavy cabs. The number of G-B Shuttle owners here on TB is ample evidence.
