Marshall Studio JMH 60th Anniversary Hendrix 20-Watt Guitar Amplifier Head with Vertical Cabinet

Legacy Forever - The Marshall Studio JMH 60th Anniversary Hendrix Half Stack Amplifier

60 years ago, Marshall and Hendrix sparked a sonic revolution. Marshall built the amps. Hendrix made them scream. Powered by the energy of combined brilliance, they rewired rock ’n’ roll. The shockwaves still echo today, louder than ever. This was never just about music. For these two visionaries, it went far beyond that. It was culture, fashion, art, and attitude. From the moment Hendrix plugged into a Marshall in ’66, they became an unstoppable creative force.

In just four years, Hendrix conquered every stage that mattered, and Marshall was always present – connected. From electrifying crowds at London and Monterey in ’67 to changing the course of music forever at Woodstock ’69, Hendrix tamed the raw power of the stack to shake the world. Hendrix’s relentless desire to push and break the boundaries of tone not only led to the birth of psychedelic funk, but also Electric Lady Studios. More than a recording space, this was a haven for future Hall of Fame musicians to jam in complete freedom. They didn’t merely make music during these sessions. They made history.

Wherever Hendrix went, Marshall was always right there with him, amplifying the beauty of what Hendrix created. It was a mutual empowerment that allowed them to constantly propel each other forward. Now, their paths are aligning once again. This time for a year-long celebration of the lasting impact of Marshall and Hendrix. One that extends beyond music into culture, fashion, art, and attitude. Expect several psychedelic product releases and other spectacular surprises. This is a partnership that’s not just about looking back; it’s a forward look and a call to inspire the next creative generation.
