1977 Marshall 2203 JMP Master Volume
Marshall · amplifier
The Marshall 2203 JMP Master Volume, introduced in the mid-1970s, was the amplifier that brought master volume control to Marshalls high-gain lineage, letting players drive the preamp into saturation without needing full stack volume to do it. That single change made heavy distortion practical at band and stage level rather than requiring a non-master-volume Plexi pushed to painful loudness, and the 2203 circuit went on to define the JCM800 sound that followed it. A 1977 example sits early in that master-volume era. It is associated in this catalogue with Angus Young, though AC/DC is generally more associated with earlier non-master-volume Marshalls.
