Fender Showman

The Fender Showman was a guitar amplifier produced by the Fender company. It was introduced in 1960 and was discontinued in 1993. Blackface and Silverface models such as the Showman, Dual Showman, and Showman Reverb employed the same "piggyback head" design as the Bandmaster and the Bassman. Dual Showman Reverb used the Fender Twin Reverb chassis and came in non-master and master volume versions with "pull boost" circuitry, mid-seventies "tailless" amp decal and a slightly larger head. The Fender Showman is often associated with surf guitarist Dick Dale. Showmans and Dual Showmans are heavily sought after by pedal steel guitar players.
