Marshall Amplification is a British company producing musical sound amplifiers and other acoustic systems. It was founded by an English musician, entrepreneur and constructor of sound equipment James Charles “Jim” Marshall in 1962. Initially, the company was manufacturing a replica of the products of Fender Musical Instruments Corporation of the USA, but later it introduced its own modifications to the equipment which was demanded by musicians seeking heavier sound instruments. After the death of Jim Marshall, in 2012, the company started manufacturing headphones and, three years later, it introduced to the mobile phones market its first smartphone “Marshall London”.
