I would also look at Victoria, and especially the Victorilux with 6L6-tubes. Although they appears to be tweeds, they have the BF-tone on board too. My Redplate Blackverb Duo 50 does a tremendous good BF-tone too. Other brands to be looked at: of course Fender, Swart, Carol Ann, Marble, Valvetech, Jackson Ampworks. Two Rock etc.
