Description

Discover Iconic Tone in a Compact Design

The Marshall SC20H Studio Classic brings the legendary JCM800 2203 amplifier to a portable, studio-friendly format without compromising its signature sound. This pre-owned gem offers the same unmistakable British tone that shaped the sound of rock legends like Billy Corgan, Jeff Beck, and Tom Morello.

Authentic JCM800 Sound

Experience the versatility that made the JCM800 a staple for guitarists across genres. From lush cleans to aggressive, high-gain overdrive, the SC20H faithfully recreates the iconic JCM800 character. Its all-valve design, powered by 2 x EL34 power tubes, ensures a rich, organic sound perfect for both stage and studio. The intuitive single-channel layout with High/Low sensitivity inputs and classic 4-band EQ puts you in control of your tone.

Perfect for Home and Studio Use

With a power reduction feature, you can switch from 20W to 5W, allowing you to achieve cranked tube amp tones at lower volumes – ideal for bedroom practice or late-night recording sessions. The DI output offers a studio-ready, mic’d-up cabinet emulation, making it easier than ever to capture your sound without the need for external mics.

Pedal-Friendly Design

Guitarists who love experimenting with effects will appreciate the dedicated series effects loop. Seamlessly integrate your modulation and time-based pedals for enhanced tonal creativity.
