Marshall Super Lead

The Marshall JMP 1959 Super Lead 100, often shortened to Super Lead or 1959, is a guitar amplifier made by Marshall between 1966 and 1981. The Super Lead was developed in response to player requests for a 100-watt amp, with several revisions to Marshall's earlier JTM45 resulting in an aggressive, midrange-heavy sound that helped establish the brand's signature "Marshall crunch". The Super Lead had two channels and four inputs but no master volume, meaning its distortion was produced by pushing its power amp to (or near) its maximum capacity. Like other Marshall amplifiers of the time, the Super Lead briefly used Plexiglas control panels, giving rise to the "Plexi" moniker in reference to these amplifier models and their characteristic sound, with the Super Lead being the most closely associated with the label. Often paired with two 4x12 speaker cabinets—a combination popularly known as the "Marshall stack"—the Super Lead has been used by many influential guitarists, among them Angus Young, Pete Townshend, Jimi Hendrix, Eric Clapton, Jeff Beck, Jimmy Page, Eddie Van Halen, and Billie Joe Armstrong. Music Radar dubbed the Super Lead "arguably the most famous amp of all time."
