The Stylophone, which came onto the market in 1968, is a simple synthesiser whose sounds are called up with a stylus on a metal keyboard. Engineer Brian Jarvis from the English company Dübreq Company originally designed it as a children's toy, but it was then used by musicians such as David Bowie, Jean Michel Jarre, Kraftwerk, Pulp and Marilyn Manson. Over three million units were sold in ten years and the Stylophone became a cult object. It was available in four different versions: Standard (S-1), Bass, Treble and 350S. Production was discontinued in 1980 and resumed in 2008.
