Product Overview

Sculpt new sounds with the Studio 900 SN20C. Built for extreme versatility and compact in design, this combo retains the original JCM900’s powerful crunch, crystalline clarity, and distinctive high-gain tone. Designed, engineered, and made in the UK, the SN20C brings the stadium-filling sound of the 90s into a portable 20W format that is perfect for the modern guitarist.

Product Description

• Iconic JCM900 DNA: The SN20C captures the spirit of the dual-channel 4100 powerhouse. It delivers everything from shimmering cleans on Channel A to the aggressive, saturated lead tones of Channel B that defined the grunge and Britpop eras.

• Three-Stage Power Attenuation: This combo offers unprecedented volume control. Seamlessly switch between 20W for the stage, 5W for rehearsals, and less than 1W (<1W) for home practice and late-night recording—all without losing the rich harmonic character of your valves.

• All-Valve Performance: True to its heritage, the SN20C is powered by two 5881 power amp valves—known for their glassy top-end and robust low-end—and a preamp section featuring three ECC83 valves (including the phase splitter).

• The G12T-75 Advantage: Equipped with a 1 x 12” Celestion G12T-75 speaker, this combo provides the classic "scooped" mid-range and punchy bass that has made this speaker a favorite in Marshall 4x12 cabs for decades.

• Pro Studio Connectivity: Featuring both a standard DI output and a Compensated DI output, the SN20C makes it effortless to capture professional-grade valve tones directly into your interface or mixing desk.

Key Features

• Dual Channel Layout: Two distinct gain stages to move between smooth rhythm and searing lead work.

• British Craftsmanship: Built in our UK factory to ensure the highest standards of durability and tone.

• Customizable Setup: While a powerhouse on its own, you can also pair this circuit with the Studio 900 Head and your favorite extension cabinets for a fully bespoke sound experience.

• Extensive Speaker Outputs: Five 1/4" jack sockets allow for flexible connection to 4Ω, 8Ω, and 16Ω loads.
