Estimated Year: 2024

Made in: United Kingdom

Overview

The Marshall JCM 900 Studio SN20H captures the classic high-gain tone of the legendary JCM 900 series in a compact 20-watt tube head format. Designed as part of Marshall’s Studio Series, this amp faithfully recreates the aggressive crunch, tight low end, and cutting mids that made the original JCM 900 a staple for rock and metal players.

This all-tube head features two channels with independent controls, allowing players to switch between clean/crunch and high-gain lead tones. The amp includes built-in reverb, a full EQ section, presence control, and master volumes for each channel. A selectable output level (low/mid/high) makes it easy to dial in the perfect volume for home practice, studio recording, or live performance.

Despite its smaller footprint, the SN20H delivers authentic Marshall tube saturation and dynamic response that pairs perfectly with a wide range of cabinets. Whether you're chasing classic 90s rock tones, modern high-gain sounds, or articulate crunch, this amp delivers the unmistakable Marshall voice.
