Marshall is making the greats portable. These amps are designed to bring a classic, authentic Marshall tone to a player that no longer needs a 100W amp or has not previously been able to afford them.
Inspired by arguably one of the most successful guitar amps in Marshall’s history, the JCM800 2203. 

The Marshall Studio Classic 20W tube amp head delivers the full spectrum of JCM800 2203 tone from rich and full cleans to heavier driven aggressive sounds in a portable format. It has a master volume, versatile EQ settings including presence control, a preamp volume control, an added effects loop and DI out.
