The Fender Bassman 100T bass head. Fender's legendary bass amp is back in all its Blackface glory - and more serious than ever. Sporting vintage Fender mid-'60s visuals and professional all-tube technology, the Bassman 100T head serves up 100 watts, along with modern features such as Fender's automatic bias, an XLR out, and two channels: vintage (classic Fender warmth) and overdrive (the responsive, aggressive sound of a modern active tone stack). You can even knock it down to a studio-friendly 25 watts. Power your bass rig with a legend - the Fender Bassman 100T.
