Hamstead Soundworks was founded by Peter Hamstead an electronics engineer with a design and development background in avionics and radar. Peter Hamstead got started in music electronics when Jim Bird asked him to replicate an old guitar amplifier. In trying to replicate it, Peter saw how he could improve it. This led to a line of Hamstead tube amplifiers and effects pedals.
