  Title: Roland Jazz Chorus
  Passage: Roland Jazz Chorus is the name given to a series of solid-state instrument amplifiers produced by the Roland Corporation in Japan since 1975.  Its name comes from its built-in analog chorus effect.  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.  It also found favour amongst funk players in America.  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.
