The legendary JTM sound that launched Marshall into rock history lives on in the ST20C, bringing that iconic 60's tone to modern players in a perfectly sized package. This handmade UK amplifier captures the unmistakable vintage character that inspired countless musicians, now available in a compact format that fits any playing environment.

Built with authentic craftsmanship, the ST20C features intelligent power reduction technology that switches between 20W and 5W output, making it equally at home in your lounge room, recording studio, or live venue. The single channel design offers two distinct voicings through four 1/4" instrument inputs with high and low sensitivity options, while classic Marshall tone controls including Treble, Middle, Bass and Presence give you complete sonic control.

The amplifier's valve-driven heart consists of 2 x ECC83 preamp tubes plus an ECC83 phase splitter, powered by 2 x 5881 power amp valves. A premium Celestion G12M-65 Creamback speaker handles the 65W power capacity, housed in a robust cabinet measuring 500mm x 460mm x 265mm and weighing 17.8kg. Multiple speaker outputs accommodate 16Ω, 8Ω, and 4Ω loads, plus there's a DI output and effects loop for maximum versatility.
