Modern technology is used in this beast to optimize classic Fender tube mojo. With six 6550s in the engine room, this arena-scorching head sports groovy mid-'60s Fender Blackface styling and two footswitchable channels - vintage (serving up classic Fender warmth), and overdrive (with the responsive, aggressive sound of a modern active tone stack). And you'll love the modern touches like Fender's Automatic Bias and the included XLR out. If you're playing stadiums - congratulations! (You probably need Fender's Super Bassman).
