This cab is a wedge shaped guitar cab. Rocktron - Velocity S112 does anyone own one/ has anyone owned one? or tried one? what's I like? it seems pretty cool and has some good reviews. it is also extremely good value and it is ported so will have THUMP. I'm wondering whether to get a couple of these or an engl 2x12 pro cab EDIT: also, as a poweramp for the cab, should I get a rocktron velocity 300 or should I wait and get an engl e840?
