+1 on the Bag End 212 (get the birch. You know you want to). Maybe not the most efficient, but like Acme, the harder you push the better they sound.
+2 on the EA Wizzy 12 M. Super efficient, very loud and easy to schlep. May not be the most bass heavy tone, but very neutral to let your bass/pedals shine through.
