ST20H
The unrivalled number one is here, just smaller. Reproducing the legendary, warm and smooth tones of the original Marshall JTM, the Studio JTM packs a punch. Swap between 20W and 5W at the flick of a switch and let the era-defining sound of the JTM steal the show, whether it’s playing at home, or on stage. Make sure to pair the ST20H with one of our Studio cabinets for a small but perfectly formed Marshall rig.
