Blended 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.42% — somewhat different

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 Mesa/Boogie Triple Rectifier is a 150-watt, three-channel all-tube guitar amplifier head introduced in 1992, running six 6L6 power tubes and five 12AX7 preamp tubes in a fixed-bias design. It launched as a heavier, higher-headroom sibling to the Dual Rectifier and helped define the raw, aggressive, bass-heavy sound of 1990s and 2000s rock and metal, with ties to nu metal, grunge, post-grunge, and hard rock acts including Korn, Tool, Soundgarden, Foo Fighters, and Blink-182. Each of its three channels offers multiple voicings, from a genuinely clean, sparkling tone through vintage crunch to Channel 3's cascading high-gain lead voicing built for detuned, heavy rhythm work. Its distinctive tube rectifier circuit and diamond-plate faceplate became visual and sonic signatures of the era. The amp is known for needing real volume to open up fully; played quiet, it can sound thin and fizzy rather than punchy.
