Nope, never owned a 5150. My guitar player has the 5150 III stack and he loves it. So much he sold his Marshall JVM. Im just a big Van Halen fan, hence the 5150. Though I was looking at the 5150 112. But Im happy with my Fender right now. I have a boat load of money in my drum kit, its just crazy how much I have spent on the guitars and amps and Im not really a guitar player, Lol. But im getting there. Should of took it up seriously years ago, but it seems I always had an excuse. Hell, Im even looking at banjo's now, LMAO!
