Anyone know anything about the Marshall 2204S heads? From what I gather, they are just a JMP 2204 in a small-size head, but I'm not totally sure. Anyone know how they sound, more JMP or more JCM 800? I'm seeing one for 600 bucks locally and I'm interested in what the deal is with this model. And how do you think it would compare with my Fargen Olde 800? Thanks fellas!
