I'm getting an Avatar 410 cab, and I'm in need of a head. I was recommened a Peavey Max 700. Does Peavey make good heads? The price is roughly $550 at the local music store, are there any other heads this powerfull in that price range? I'm mainly concered with it being able to go down to 2 ohms so I dont need to get a new head if I ever wanted to slap a 15" on the bottom.
