Check out mesas website. the Mark V is finally here. I gotta have one. I sold my Mark IV a long time ago to get a rectifier and ive been kicking myself ever since. The mark IV is the tightest, most *** kickin rock/metal amp ive ever played through ( once i figured out how to tweak it LOL!) Im very excited to here the new Mark V. Might have to sell off my MTS gear...
