By the end of 1965 a production of 40 amplifiers and 100 cabinets per week was unable to reduce the growing back orders. Demand, fuelled by the appointment of a distribution company, exploded. The world was crying out for more Marshall. The solution was another move. Marshall now moved to Bletchley, Buckinghamshire into 7000 sq.ft. Export sales grew as the success of British bands spread abroad. Throughout the 1960's Marshall sound powered the most influential and original guitar players. From Pete Townshend with The Who, Eric Clapton with his distinctive Bluesbreaker tone, then with Cream; to Ritchie Blackmore with Deep Purple and the greatest ambassador of all, Jimi Hendrix. With his prodigious guitar talent, he used the power of Marshall as a creative tool and as an extension to the instrument itself. 1968 and the sales explosion created the need for greater capacity. A 14000 sq.ft. purpose built factory was opened and at last the world market stood a chance of fulfilment. Investment in massive PA systems powered the tours of many early 70's “super groups”. Multi coloured Marshalls appeared and the product range expanded.
