Corcostra x Marshall JTM Full Rig | Green Edition

One of a kind. One of a set. One chance.

This is the complete rig — a matched head and cabinet collaboration between Marshall and Corcostra that exists nowhere else on earth.

The Head: A one-of-one Marshall Studio JTM ST20H, born from an unprecedented partnership between two legendary names. Not a limited edition. Not a small batch. One amplifier, verified and documented, finished in Green/White Levant. It carries the DNA of Marshall's very first amp — two channels, bridgeable, 20W/5W valve switching, and a tone palette that spans smooth to crunchy with everything in between.

The Cabinet: The Studio JTM 1x12 Cabinet, custom finished in Green Levant with a Black and Grey grid — designed and built in the UK to pair perfectly with the ST20H. Loaded with a Celestion G12M-65 Creamback speaker, it delivers that definitive vintage Marshall tone in a compact, portable form.

Together, they form a complete, matched rig that will never be replicated. Museum-grade provenance. Collector-documented. Built in the UK. Inspired by the amp that started it all.

Includes certificate of authenticity and commemorative collaboration badging.
