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 Park P45H is a 45-watt head reviving the smallest of the original marque's mid-sixties builds. Forty-five-watt British circuits of that era sit before the Plexi brightening, so the voice is warmer and rounder with a more gradual, forgiving breakup — closer to the JTM lineage than to the Super Lead. The lower rating also means it reaches that breakup earlier than the 50 and 75 watt heads. It suits blues, blues rock and classic rock players after the earliest British amp character rather than the sharper Plexi bite.
