The 1977 Marshall 2203 JMP Master Volume and the Engl 120 E610 MK II are both amplifiers sharing crunchy. The 1977 Marshall 2203 JMP Master Volume leans mid-forward and high gain. The Engl 120 E610 MK II leans saturated and transparent.

Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

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.

The ENGL Savage 120 MkII (E610II) is a 120-watt all-tube 4-channel guitar amplifier head from ENGL Amplification, Germany. Four channels — Clean, Crunch I, Crunch II, and Lead — offer a comprehensive tonal range with MIDI switching, an integrated noise gate, and extensive tone-shaping controls. The Savage 120 is particularly praised for its mid-rich high-gain character at extreme volume settings, maintaining note clarity and tightness in metal and hard rock contexts.
