i'm looking for a new amp. i want an amp that can be loud and aggressive but yet gentle and firm at times. i want to go with a stack also. i'm looking at the behringer ultrastack bg412s. i really like that cab but behringer dont make heads so i really dont want say a marshall head with a behringer cab. i thought about getting a power amp instead of a head. what do you guys think? should i keep looking for a good head or just go with a power amp? also, is there anything else that anyone might think would be a better fit for me. i'm also on a bit of a price range. i really dont want to go over the $600-700 range. thanks everyone
