Dewtron (Design Engineering (Wokingham) Ltd. or D. E. W. Ltd.) were a small British manufacturer of modular synthesizers which were sold to customers in kit form or as built units. It was founded by Brian Baily on 5 February 1964 in Wokingham, Berkshire. By 1970 the company's products included oscillators, voltage controlled amplifiers, sample and hold and envelope shapers.
Mike Rutherford used a Dewtron "Mister Bassman" bass pedal synthesizer on Genesis albums from Nursery Cryme (1971) onwards, before replacing it with a Moog Taurus I for the album A Trick of the Tail (1976). Yes' frontman Jon Anderson used a similar unit in live performances. Chris Carter, later to form Throbbing Gristle, experimented with Dewtron kit-based synthesizers early in his music career.
