It's one of the chrome ones from around 1999/2000, through a rough as hell 4x10 (4ohm), with a precision. Had a good mess with it last night. At loud volume a 15" speaker would be good I think but most times I'd use it outside of practice there is usually be a cab to share anyway. Not the best at very low volume but that's not what it's made for and I have my "little bastard" to cover that. I think I'll be chuffed for a while.
