It would all depend on which you're talking about. If you're a metal head and prefer a ton of gain you should get Dimebag Darrel's Warhead stack that Randall made him. It's a 350 watt solid state head with one 4x12 cabinet and one 2x15 cabinet. The lows and highs on this thing are incredible. The only thing it doesn't have is the warm tone of a Marshall tube amp. But hey, nothing's perfect.
I'm off like a herd of turtles in the moonlight!
Ain't nothin' but a Gear thang, baby!
