Farrant guitar amplifiers were made in the 1960s and distributed by Stroud Audio in Stroud, UK. There were three models: 15, 30 and 50 watts and they were supplied as separate main amplifiers and preamplifiers, with a tremolo circuit. The company was founded by Stewart Farrant but went into receivership in 1968.
