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.73% — moderately similar

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Ceriatone JTM45/100 is a point-to-point hand-wired reproduction of the 100-watt version of the Marshall JTM45 circuit, the design sometimes referred to as the Bluesbreaker-era Marshall scaled up for larger venues. It keeps the warm, thick midrange and Bassman-derived character of the 45-watt original while adding substantially more headroom and volume, so breakup arrives later and the amp stays cleaner under hard playing. That extra power makes it better suited to stage use or to players who want a louder clean platform with classic British colouration. It suits blues rock and classic rock players who want early Marshall tone at volumes the smaller version cannot reach.
The Ceriatone JTM45 MkII is a point-to-point hand-wired reproduction of the Marshall JTM45, the amplifier that started the company and was itself closely derived from the Fender 5F6-A Bassman circuit. That heritage gives it a warmer, rounder character than later Marshalls, with a thick midrange and a softer, more gradual breakup that sits between American and British voicings. It uses GZ34 tube rectification, which contributes a degree of sag and compression under hard picking that the later solid-state-rectified Marshalls do not have. It suits blues, blues rock and classic rock players who want the earliest Marshall voice rather than the brighter, more aggressive Plexi and JCM800 sounds that followed.
