The Jazz Chorus series became increasingly popular in the late 1970s and early 1980s new wave and post-punk scenes because of its clean yet powerful sound, durability and relatively low cost when compared to the more commonly used tube amplifiers of the time such as Marshall or Fender.
[1] It also became popular to use for clean tones in heavy metal, with the most famous users being James Hetfield and Kirk Hammett from Metallica, and Wes Borland from Limp Bizkit.
The amplifier features high and low inputs, a bright switch as well as a three band equalizer and volume for each channel.
Summers' use of the amp in turn inspired, for instance, Jeff Buckley, whose first amplifier was a Jazz Chorus.
Other users include Steve Levine, producer of bands such as Culture Club, The Beach Boys and The Clash.
