    Description

    The legendary JCM800 tone, with new modifications including a gain boost switch.

    Discover a world of unparalleled tonal flexibility with the Marshall JCM800 Modified. Inspired by the legendary original JCM800, this modified iteration honours its iconic status as the go-to amp for iconic bands such as AC/DC, The Ramones and the Red Hot Chili Peppers. It draws inspiration from a global community of players experimenting with crafting their ideal tone, embracing the rich culture of modded Marshall amps.

    This revamped amp is equipped with modern features, a gain boost, mid-boost and a tight switch, providing unparalleled tonal flexibility for today's guitarists. Craft the perfect sound for any genre with the ability to transition from smooth, warm breakup to high-gain roars seamlessly. This modified version ensures you'll stand out on stage and captivate any crowd, all while retaining the classic JCM800 tone at its core.
