The JTM45 was the first Marshall amplifier, and essentially remains as the end-all-be-all for collectors and tone-crazed guitar slingers alike. The highly sought-after Marshall JTM45 MK II amplifiers rocked the world when they were introduced in 1963 after a short run of garage-built prototypes. Electronically, these early Marshalls are basically clones of the 1959 Fender Bassman amp, but the use of different preamp (ECC83) and power amp (5881 or KT66) tubes in the JTM45 gave them a raucous, present voice all their own.
