The electronics men and the birth of the sound system
Well supported
Before there were selectors and deejays, there was the amplifier, and the men who built it.
How a wartime radar engineer's 1947 amplifier turned a stack of records into a sound system, and made the electronics man the hidden founder of Jamaican music.
A circuit before a song
The story of Jamaican music usually starts with a voice. But the machine came first. When Hedley Jones returned from wartime service as an RAF radar engineer, he brought back an intimate command of valves, transformers and high-frequency circuits, and put it to work building amplifiers that could reproduce the full sweep of the audio spectrum in a Kingston dancehall.
His 1947 Jones-model amplifier was the object Tom Wong acquired and named a 'Sound System'. The name stuck to the whole apparatus, but the innovation was electronic: a purpose-built amplifier loud and clean enough to make recorded music a public event. Jones soon wired rigs for rivals including Duke Reid and Coxsone Dodd.
The ingenuity of scarcity
Jones had already built himself a solid-body electric guitar in 1940 because he could not afford an imported one, a small act of import-substitution ingenuity that would define the culture. The home-built ethos made the amplifier a thing you fabricated, not merely bought, and set the template for the valve amplifier era that followed.
The sound system's first author was an engineer, not a singer.
That lineage, from wartime radar to the sound-system amplifier, reframes the origin of Jamaican music as an electronics story. The men who wound the coils and biased the valves were the hidden founders, and the dance was, from the very first night, an achievement of engineering.
