The JCM800, 2203 model (’81–’84), is one of the most highly respected 100 Watt Marshall heads. Originally evolving from the ‘Plexi’ head, the JCM800 was one of our first amplifiers to feature a Master Volume control.

The JCM800 2203 remains the essence of simplicity, it has one channel with no Reverb. Its easy control panel, distinctive roar, and larger-than-life edge immediately set the standard by which all other rock amps were judged and it remained the industry benchmark throughout the entire 16 years of its production life.

Its purist-pleasing front panel and distinctive roar set the standard by which all other rock amps were judged. And it is still produced because of continued artist use, and of course by popular demand.

‘Playing through the 2203 is like flicking a switch for instant metal-hero status: imperious rock tones roll out effortlessly from your fingertips.’ The Guitar Magazine
