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 2245 is a reissue of the JTM45, the very first Marshall amplifier from 1962, built on a 5881/KT66 power section that gives it a warmer, more American-influenced voice than later EL34 Plexis. At around 30 to 45 watts it offers a smooth, bluesy breakup with rich harmonics and a slightly looser, vintage feel. Its warm cleans and creamy overdrive made it a cornerstone of British blues-rock. The simple four-input front panel recreates the original early-1960s circuit.

The Marshall Bluesbreaker is a legendary overdrive pedal that launched the genre of modern overdrive effects. Its warm, singing midrange and natural response made it an instant classic when introduced. The Bluesbreaker has influenced countless overdrive designs and remains a studio and stage favorite for blues, rock, and alternative applications.
