I'm currently running a 4x10 and 1x15 stack with an acoustic b200h head and a boss me-20b. Looking to upgrade amp around april, should i stick to the acoustic head (i do enjoy the 200 watt version) or the lowdown i played one at guitar center and was intriuged by the tones i could achieve. help me decided, im open to any suggestions in the price range up to about 500 dollars. thanks
