King Tubby

Dub music had to come from somewhere, and the consensus is that it came from the mind of Osbourne Ruddock, aka King Tubby.
Born in Kingston, Jamaica, in 1941, Tubby began his career in the mid-1950s repairing radios and DJ sound systems.
Tubby was the first soundsystem operator to use high-frequency horn tweeters, which he'd string up in trees at his dances.
King Tubby set up a studio at an aunt's house. The singer's booth was formerly the toilet.
The circuits at reggae eccentric Lee Perry's Black Ark, which famously burned down, were designed by King Tubby.
