I like the Avatar B410. It looks like a great value for all the watts you get for only $390 shipped. What I'm asking is if it really matters what head you have. As long as it is decent, the cabinet is really the deciding factor in how loud the thing is, right? So even though the head might have say, 200 watts, the cab will still perform loud? Would it benefit me to get the cab in a 4 ohm version just so the head will produce more power? Thanks for your help.
