With its modern enhancements and versatile features, the JCM800 Modified is ready to inspire a new generation of players.

The Sound That Defined an Era

The Marshall JCM800, introduced in the early '80s, quickly became the go-to amp for countless artists, from punk rockers to heavy metal legends. Its aggressive, high-gain sound and unmistakable punch graced stages worldwide, solidifying its status as a true rock and roll icon.

The addition of a gain boost switch provides unparalleled gain and tonal flexibility, allowing you to seamlessly transition from smooth, warm breakup to commanding high-gain roars. The mid-boost switch enhances the midrange frequencies, bringing warmth, depth and clarity to your tone, while the tight switch cuts low frequencies for a punchy and well-defined sound. These enhancements provide modern players with the tools they need to shape their sound and explore new sonic territories.

With its signature 100-watt power and aggressive gain structure, the JCM800 sound is faithfully reproduced, delivering the same raw power and dynamic response that defined a generation of rock and metal music. The added gain boost, mid boost, and tight switch provide modern players with the tools they need to shape their sound and explore new sonic territories.
