I have a Cornford MK50 II, Cornford Hellcat, Suhr OD100SE+, TopHat Emplexador & a Bruno Cow Tipper pro35. All of them do cleans and all are great and different from each other. Favorite by a little bit is the Bruno-fuckin pricey magic.
More interesting responses, again some amps I never would have thought to have very nice clean sounds. The clean amp I like the most right now is a Fender Blues Junior. I wish I had access to some of these other amps, Im looking to replace the amp I have right now since my style and ears have changed so much since I bought it. I feel so deprived only having GC's around me
