The Marshall Super Lead Model 1959 is a guitar amplifier
head made by Marshall

Its output was first channeled into an 8x12" cabinet, but that single, unwieldy cabinet was quickly changed to a set of 4x12" cabinets, creating the "Marshall stack." The amplifier also came as a PA

The Plexiglas panel led to the name "Plexi," and, while 50-watt models of the time are also called Plexis, the 1959 100 watt model is often referred to as the "original" Plexi.
In 1969, Marshall replaced the Plexiglass panel with one of gold aluminum. There were other modifications: the KT66
tubes were replaced with EL34
. After 1976, the plate voltages were lowered slightly for improved reliability. But during the 1970s, Marshall's increasing exports overseas led to a problem: often the EL34 tubes would break during transportation, to the point where amps began being shipped from the factory with more rugged 6550 tubes, which are "stiffer and not as harmonically rich" as the EL 34 tubes.

tubes; it had three ECC83
tubes in the pre-amplification stage. A model with tremolo
, the 1959T, was available until 1973.
The amplifier had four inputs into two channels. The lead channel has a boosted bright tone, and the rhythm channel has a flat response. Each channel has a high and a low gain input; the low gain input is attenuated by 6dB. The channels can be linked with a jumper cable.

combo for a 1959 Plexi, and Jimi Hendrix

Reissues
The amplifier was reissued for the first time in 1988 (the 1959S), and again from 1991 to 1993 (the 1959X) and from 1993 to 1995 (the 1959 SLP). In 2005, Marshall introduced the 1959 HW (for "hand-wired"), based on the 1967-1969 models, with negative feedback added corresponding to the 1969 model.
