Marshall Jimi Hendrix Studio Vintage JMH 20W Valve Amp Head

Built by hand in Marshall's factory in Bletchley, UK, this portable JMH Studio amp head reimagines the classic Studio Vintage amplifier. From expressive cleans and rich blues tones to biting overdrive, the Marshall JMH Studio captures the spirit of the Plexi era and serves up the iconic sounds that helped define Jimi Hendrix's legacy.

This latest unveiling marks the final release in the Marshall x Hendrix 60th Anniversary Collection, celebrating the enduring connection between two true music legends.

Big tone, compact package

The Studio JMH is an all-valve amp head that delivers roaring Marshall character in a more manageable format for modern players. Explore a wide range of sounds via four separate inputs, from sparkling cleans to bold British crunch. And thanks to Marshall's built-in power reduction, you can switch from a gig-ready 20 watts down to 5 watts — making it equally at home on stage, in the studio or in your practice space at home.

Psychedelic looks inspired by Jimi

This limited edition head looks every bit as wild as it sounds. A striking black and purple swirl adorns the control panel, creating a cool cosmic vibe that’s complete with a purple LED indicator for an extra touch of mojo. Intricate silver beading runs throughout the design, inspired by Jimi's iconic jewellery, while the Hendrix-derived all-seeing eye badge pays tribute to one of rock's most influential artists.

A word from Marshall

“Jimi was a formidable musician, a real force of nature. He took everything to a new level and carried everybody with him. When he played, it was an emotional time for everybody because everyone was thinking, if he can do it, I could maybe do it. And he's using Marshall, therefore we want Marshall. It was a really special time for us all and there’s no doubt that we grew with him and his fame, it was a natural tie-up. The rest is history, as they say.” — Terry Marshall, co‑founder of Marshall Amps
