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 Marshall's Studio cabinets for a small but perfectly formed Marshall rig.

OUTSTANDING MARSHALL SOUND
An unmistakable sound that is recognised all over the world, the ST20H is a loving homage to the amp that responded to the rock’n’roll revolution. From its legendary warm and smooth tone to blending the voices for a combination of crunch and clean, the ST20H brings the outstanding sound that Marshall is so well known for.

COMPACT WITHOUT COMPROMISE
Accurately recreating the iconic look seen across thousands of stages over the years, the ST20H has the power of a classic Marshall amp in a new, more compact design. Packed with the same vintage tones you know and love, just in a smaller package. Features such as a DI out and FX loop have been added, bringing the JTM into the present day.

POWER REDUCTION
Whether you're playing at home or an intimate gig, swap between 20W and 5W at the flick of a switch thanks to built-in power reduction technology. The 5W mode allows playing at a lower wattage without compromising on tone.

UK-MADE AND ALL-VALVE
Handmade in the same UK factory that has been manufacturing Marshall amps since the late 60s, the ST20H is built on decades of experience with expert craftsmanship at the very heart. Loaded with two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter, the ST20H takes you right back to the renaissance of rock’n’roll.
