Vintage 1970 Marshall Major 200W Head.

The Marshall Major is one of the most powerful and commanding amplifiers ever produced during Marshall’s early era. Known for its massive headroom and unmistakable presence, it delivers the kind of scale and authority that defined some of the loudest stages in rock history.

Built for players who want maximum power, clarity, and impact, the Major stands apart from smaller amplifiers with its ability to stay articulate at extreme volumes while maintaining a bold, dynamic response.

This is a serious, high-powered vintage amp for those who understand what these are and what they’re capable of.
