Marshall Marshall 2203 Reissue preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Marshall 2203 Reissue reproduces the circuit of the original late-JMP/early-JCM800 2203 Master Volume 100W, offering players access to the iconic single-channel, master-volume plexi tone with new-production components and modern build quality. Faithfully capturing the high-gain preamp character and full-power EL34 output stage of the original, it became a popular choice for players who wanted period-correct tones without hunting the vintage market. The reissue maintains the original's single-channel simplicity and has been praised for its tonal accuracy relative to genuine late-1970s examples.
