Marshall's Early Amplifier Development
Jim Marshall began producing amplifiers in 1962 at his London shop, initially cloning Fender circuits before developing the JTM45. By 1965, the company introduced the plexiglass-fronted Super Lead heads that became known as Plexis.
Key Model Evolution
The 1959 100-watt and 1987 50-watt heads, along with matching 4x12 cabinets, defined the Plexi era from 1965 to 1969. Circuit tweaks in 1966 and 1967 altered negative feedback and capacitor values, shifting the amp from early JTM45 voicing toward brighter, more aggressive gain.
Notable Artists and Signature Sounds
Jimi Hendrix used 1959 Plexis with 4x12 cabinets for Woodstock and studio recordings, while Jimmy Page employed both 50-watt and 100-watt Plexis on Led Zeppelin albums. Pete Townshend and John Bonham also powered large stacks of these amps for live volume and sustain.
