Marshall Studio (ST20H) 20W All-Valve JTM Amp Head with ST112 Studio JTM 65-watt Extension Cabinet

Marshall Studio ST20H JTM Amp Head with Power Reduction Technology, DI Out and FX Loop

The unrivalled number one is here, just smaller. Reproducing the legendary, warm, and smooth tones of the original Marshall JTM, the Marshall Studio ST20H JTM packs a punch. Swap between 20-watt and 5-watt 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 the Marshall Studio cabinets for a small but perfectly formed Marshall rig.

Outstanding Marshall Sound

An unmistakable sound that is recognized 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 20-watt and 5-watt 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.

Marshall ST112 1x12-Inch Extension Cabinet for Marshall ST20C with G12M-65 Speakers

The Marshall ST112 brings the iconic tone that sprung Marshall to the forefront of rock ’n’ roll in the ‘60s to today. This 1x12-inch cab has been designed to be paired with the ST20H to create a small but perfectly formed vintage rig, or used as an extension cab for the ST20C. It is handmade in the same UK factory that has been manufacturing Marshall amps since the late ‘60s, built on decades of experience with expert craftsmanship at the very heart. The smaller scale of the ST112 gives players the power of the authentic Marshall tone, in a more compact design. With Creamback Celestion speakers, this cab offers that definitive vintage tone.

Key Features

Packed with the same vintage tones you know and love, just in a smaller package. With G12M-65 Creamback Celestion speakers, the ST112 brings the outstanding sound that Marshall is so well known for. Expertly crafted in Bletchley, England, adorned with period-correct aesthetics from the same distinctively solid metal, red enamel poured ‘coffin’ logo to its fawn fret complete with gold piping and beading.
