Deacy Amp

The Deacy Amp (pronounced "Deeky" /ˈdiːki/) is an electric guitar amplifier created in 1972^[1] by Queen's bassist John Deacon, who is an electronics engineer by training. The amplifier circuit board from a Supersonic PR80 portable radio found in a builder's skip (dumpster) was fitted into a speaker cabinet and powered by a 9-volt battery. The amplifier had no volume or tone controls and for most of its history it was never broken and thus never repaired. It was used along with Queen lead guitarist Brian May's Red Special electric guitar and treble-booster to produce sounds reminiscent of various orchestral instruments, such as violin, cello, trombone, clarinet, or even vocals, starting from the songs "Mad The Swine" (an unreleased song from the 1973 album Queen) and "Procession" from the 1974 album Queen II.^[2]
