It conjures up everything from rich and full cleans to high-gain mayhem, but in an amp you can carry with one hand. The Studio Classic is loaded with all the player-friendly features you need, including a master volume, 3-band EQ with Presence control, preamp volume, effects loop, and DI output. You also get a power reduction circuit for attaining cranked-up tones without violating a noise ordinance. When you want JCM800 tone but aren’t rocking in an arena, reach for the Studio Classic — it delivers the goods.

JCM800 — the professional rocker’s choice amp

The Studio Classic is a low-watt version of Marshall’s coveted JCM800 2203. So, who loves the Marshall JCM800 2203? More guitarists than we could ever name, and some of the most famous guitarists of all time would be on the list. Angus Young of AC/DC, Kerry King from Slayer, and Zakk Wylde are just a few of the hardest rockers on earth that chose the JCM800 2203 for its tonal tenacity. If you’re looking for an amp that will deliver clean tones, look elsewhere. If you want maximum tonal aggression, plug into a Studio Classic — it delivers true-to-life JCM800 tone!

Loaded with all the player-friendly features you need

Consider yourself lucky, because the Marshall Studio Classic sports features not found on the original JCM800. An effects loop makes integrating your pedals and external processors a breeze. Attaining cranked tones at listenable volumes is a breeze thanks to a power reduction circuit. You also get a DI output for easy recording or routing to a PA. The guitarists at value the Studio Classic’s modern flexibility almost as much as we appreciate its vintage tone.
