Anyone tried one yet? Did a search and not much. Also searched the internet and not much. I will soon be buying a second Ampeg cab to put under my 410he. I'm using a B4r 350x 350 watts. I've narrowed it down to either a second 410he, the SVT15e, the new 4 ohm 18 cab or this 412. Hey Ampeg insider, I only live about an hour or so from STL. can I come down and try all these cabs at the factory?
