Brit TM45 Patch
The Marshall JTM45 is the first guitar amplifier produced by Marshall, initially released in 1963. Named for Jim and Terry Marshall (JTM) and rated at 45 watts (45), it was developed after London guitarists requested an alternative to imported American Fender amplifiers. While based on the Fender Bassman circuit, the JTM45 featured an all-aluminum chassis, Celestion speakers in a closed cabinet, and modified feedback circuitry that gave it a distinctive British snarl. Early versions used 5881 power tubes, later replaced by KT66s. The amp was first publicly tested at the Ealing Club in September 1963 and went on to be used by David Gilmour, The Rolling Stones, and Jimi Hendrix. The 2x12 combo version was famously used by Eric Clapton on the legendary 'Beano' album with John Mayall's Bluesbreakers.
