Oregon-based Sunn Musical Equipment Company was formed in 1965 to provide rock and roll musicians with loud, roadworthy amplification. Sunn amps were used by such '60s bands as Mountain, The Who and the Jimi Hendrix Experience. Sunn also sold budget Strat style electric guitars in the 1980s and 1990s under the Sunn Mustang brand name. Sunn was ultimately acquired by Fender, who discontinued production of the line in the early 2000's.
