Well, I've got both a JCM 800 and a 900. The 900 is much more suited for blues and the 800 is suited for rock/metal. I would say go with the 800, it's more versatile than the 900's, just roll off the gain a bit and you can get a good bluesy sound....I don't care much for the 2000's either, they do sound thin to my ears also...
