FACTOIDS & TRIVIA
Norm Sundholm was the bassist in the band The Kingsmen
(of “Louie Louie” fame) and he was constantly blowing up and/or modifying
is Fender Bassman and Bandmaster amps. These Fenders were never
very good bass amps to begin with, so Norm and his brother, Conrad began
building their own bass guitar and PA amplifiers in their garage in Portland,
Oregon. Their amp designs were bullet proof and their speaker cabinet
designs were acoustically very efficient. As word spread, the fledging
company took off and moved out of the garage to a larger building.
At this point, demand outweighed production, so between 1966 and 1969 Sunn
had the power amp sections of the circuit and transformers supplied by
Dynaco, makers of high quality, high end stereo tube amplifiers.
Sunn produced some of the first available high powered bass rigs in the
late 1960s and were considered industry standards along with the Ampeg
SVT. Unfortunately, the company went through some hard times in the
mid-1970s. Sunn was not able to compete effectively once other companies,
such as Ampeg, Fender and Acoustic, had introduced powerful and reliable
bass amps. The company was bought by Fender in the early 1980s which
relocated all of its amp production to the Sunn facility in Oregon.
Sunn tube amplifiers are no longer made, but Fender’s solid state PA equipment
bears the Sunn name. The 200S shown was the most popular of the Sunn
bass amps and was based on the Sorado model which preceded it. Due
to the limited production of such a small company, Sunn amps are relatively
hard to find today.
