Marshall ST20C Combo

The Marshall ST20C Studio JTM Combo captures the soul of the original JTM45 in a portable, studio-ready 20-watt combo. Handcrafted in Bletchley, England, this all-valve amp delivers the warm, rounded tone that defined the birth of British rock—complete with rich harmonics, smooth overdrive, and dynamic response. With a built-in power reduction down to 5 watts, it’s equally at home in small venues, the studio, or at home practice volumes.

Featuring a single channel with both treble and normal loudness controls, a classic 3-band EQ plus presence, and a G12M-65 Creamback speaker, the ST20C offers all the tools you need to sculpt authentic vintage tone. It also includes a DI output for direct recording or live sound, as well as multiple speaker outputs for flexible rig setups. For players who want legendary tone in a compact and manageable combo, the ST20C delivers the full Marshall experience with elegance and simplicity.
