I have a Clubman and I wouldn't say this amp has the best cleans in the Fender Blackface sense, it's more like a tweed amp as it gets gritty pretty quick. It does however the thick full bordering on the edge of distortion (real light break up) sound in spades, I don't think I have heard anything better yet.
Between the Clubman, C-30, Lightening, and Chieftain, all of which I've owned, my vote goes to the Chieftain, for beautiful cleans. It also breaks up great, especially with P-90s, or humbuckers. When I want great chimey strat tones, I go to the Chieftain. It's my one do-all amp.
