Marshall Plexi (1959 Super Lead)

The Marshall 1959 Super Lead, known universally as the Plexi for its gold-tinted plexiglass control panel, is the amplifier that defined classic rock tone. Introduced in 1965, its 100-watt EL34 power section delivers harmonic saturation and sustain when pushed to volume, producing the iconic crunch that powered Hendrix, Led Zeppelin, and Van Halen. The non-master-volume design means the amp must be driven hard to achieve its signature breakup, making it brutally loud but tonally unmatched.
