Jim Marshall first went into business in the early 1960s with a small shop in Hanwell, London, selling drums, cymbals and drum-related accessories; Marshall himself also gave drum lessons. According to Jim, Ritchie Blackmore, Pete Townshend and other guitarists frequently would come into the shop and ask why Marshall was not selling or producing guitar equipment. [2] Marshall Ltd. later expanded and started selling guitars and amplifiers, the most notable of which at the time were the Fender amplifiers imported from America. These were very popular with guitarists and bass players, but also very expensive.
Jim Marshall thought he could produce an equivalent product for less money. He enlisted the help of his shop repairman Ken Bran and an unknown EMI technician named Dudley Craven and between them they decided they most liked the sound of the 4x10" Fender Bassman. They made several copies similar to, but at the same time a bit different from the Fender. The sixth prototype was in Jim's words, the "Marshall Sound." [3]
The first few production units were almost exactly the same as the Bassman circuit, with US-origin transformers and military surplus 5881 power valves. The first difference was the cabinet used, as Marshall decided to build separate amplifiers and speaker cabinets, and as they were originally intended as bass amplifiers, Marshall chose to use four 12 inch Celestion speakers in a closed back cabinet, instead of the Bassman's four 10 inch Jensen speakers in an open back cabinet. This new amplifier, tentatively called the "Mark II", was eventually named the "JTM45" after Jim and his son Terry Marshall, and "45" as, in theory, it produced 45W of power
