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 Suhr PF100 is Peter Frampton's 100-watt signature all-valve head, a hand-built take on the classic British plexi voice developed with the rock legend. With EL34 power and footswitchable channels, it delivers open, dynamic cleans and a thick, singing plexi-style overdrive tuned to Frampton's expressive lead tone, aimed at classic-rock players wanting vintage Marshall flavor with modern refinement.
