After using Meazzi Echomatic machines, Hank Marvin of the Shadows began using Binson echoes.
Echorecs were used by Syd Barrett, David Gilmour, and Richard Wright of Pink Floyd.
The Echorec can be heard on Pink Floyd songs including "Interstellar Overdrive", "Astronomy Domine", "Shine On You Crazy Diamond", "Time", "One of These Days", and "Echoes".
