THE AMP THAT’S ONE IN A HUNDRED

To mark Celestion’s 100th anniversary and our 60+ year relationship, we gave the Studio JTM a special redesign. Available in a limited run of only 100, this UK-made amp comes in a new cream colour with an anniversary Alnico Celestion speaker, making it a true collectible. If you ask us, the only right way to celebrate 100 years, is this way.

Outstanding Marshall sound

When Marshall and Celestion join forces there’s only one result; era-defining sound. This amp continues the legacy by featuring an anniversary speaker, inspired by the first speaker built for electric guitars.

Handmade in the UK

Celestion 100 is made in the same UK factory that has been manufacturing Marshall amps since the late 60s. We assembled each amp by hand so you can feel the heart and soul of Marshall every time you play.

Iconic styling

The Celestion 100 design brings together classic details such as the solid metal, red enamel poured ‘coffin’ logo, with all-new features such as the white knobs, cream covering, and unique numbered plaques.

Vintage sound for the small stage

Swap between 20W and 5W at the flick of a switch. Whether you’re playing at home, or on stage, let the era-defining sound of the anniversary Celestion speakers in this limited-edition Studio JTM steal the show.

Powerfully compact

At home or recording in the studio, the Celestion 100’s compact and portable 1x12” cab is made for on-the-go sessions. Its versatility allows you to play your music anytime and turn anywhere into a stage.
