The Studio JTM recreates the legendary, warm, and smooth tone of the original Marshall JTM and packs a punch. Switch effortlessly between 20W and 5W and let the epic sound of the JTM steal the show, whether you're playing at home or on stage. Pair the ST20H with one of our studio cabinets for a small but perfectly shaped Marshall rig.

Outstanding Marshall Sound

With its unmistakable, globally recognized tone, the ST20H is a loving tribute to the amplifier that responded to the rock'n'roll revolution. From its legendary warm and smooth sound to blending voices for a mix of crunch and clean, the ST20H delivers the outstanding sound Marshall is famous for.

Power Reduction

Whether you're playing at home or at an intimate gig, the built-in power reduction lets you switch between 20W and 5W with just the push of a button. In 5W mode, you can play at lower wattage without compromising on tone.

Compact Without Compromise

The ST20H is an exact replica of the iconic look seen on thousands of stages over the years, delivering the power of a classic Marshall amp in a new, more compact design. Packed with the same vintage sounds you know and love, just in a smaller package. Features like a DI output and FX loop bring the JTM into the present.

UK-Made All-Tube

The ST20H is handcrafted in the same British factory where Marshall amps have been made since the late '60s, based on decades of experience and craftsmanship. Equipped with two ECC83 preamp tubes, two 5881 power tubes, and an ECC83 phase splitter, the ST20H transports you straight back to the rock'n'roll renaissance.
