So today i visited my local Guitar Center and i got to try em all out. I tried out every SWR head with a mix of all of the SWR cabs and the Mesa Cabs. And then i got to try out the Ampeg heads and cabs as well. After playin with all of them, i tell ya, i love Mesa gear over them all. My next rig will most definately be two Mesa 4x10 cabs and a Mesa Bass 400+.
