Marshall - 20W Studio 900 Valve Amp Head #SN20H
The Studio 900 resurrects the beloved sound forged in the 90s with Marshall's hallmark power and precision, while updating it for today through a compact design for use in home studios or professional settings. It faithfully reproduces the iconic JCM900 crunch, ensuring authenticity even at lower volumes—just like the original amp, famously played by guitar legends such as John 5, Nita Strauss, and Phil Campbell.
With two channels easily controlled through a footswitch, its innovative hybrid design blends the warmth of valve technology with the reliability of solid-state components, ensuring consistent performance across a wide range of playing styles.
Equipped with two ECC83 preamp valves, two 5881 power amp valves, and one ECC83 phase splitter, the Studio 900 Head mirrors the renowned 100-watt head, offering musicians unparalleled control and the rich, dynamic tones that define Marshall's legacy. Players can effortlessly switch between 20W, 5W, and <1W power attenuation settings, adapting the amp's output to any venue or recording environment.
The built-in spring reverb allows you to add rich, dynamic depth to your sound, amplifying the impact of your solos. With customisable settings, you can adjust the reverb intensity to suit any genre, offering complete control over your tone.
Crafted in Marshall's renowned Bletchley facility in England, the Studio 900 exemplifies the brand's dedication to superior craftsmanship. Sharing its circuit design with larger, more established models, this amplifier ensures the exacting standards and timeless sound of vintage Marshall amps.
With its blend of modern innovation and traditional craftsmanship, the Studio 900 not only pays homage to Marshall's storied history but also sets a new standard for compact, high-performance amplifiers that musicians can rely on for years to come.
