Marshall’s Studio series has long served as a Suhavimart favorite, as it perfectly packs many of the company’s iconic amplifier models down into compact, gig-and-studio-ready combos and heads. From the Super Lead to the Silver Jubilee, the Studio series encompasses almost the entirety of Marshall’s long history — with the ST20C Studio JTM, it reaches all the way back to the beginning. This 20-watt, 1 x 12-inch combo amplifier precisely replicates the creamy highs, loose lows, and smoky overdriven tone of the original Marshall 2245 — the platform that arguably defined the biting sound of British blues rock, while also setting the stage for Marshall’s later amplifier creations. Plus, while it’s certainly a vintage throwback, the ST20C Studio JTM comes equipped with all the Studio series’ usual bells and whistles, including a 5-watt power scaling mode, FX loop, and speaker-emulated DI output. Vintage-inspired from the metal “coffin”-style logo to the levant front covering, the UK-built ST20C Studio JTM is a top-tier tonal tribute to the model that began the Marshall legend.
