How It Was Recorded

Leslie Leslie speaker

Rotary speaker cabinet, 1941 onwards. An amplifier feeding a rotating treble horn and a rotating drum around the bass speaker, giving tremolo and vibrato by the Doppler effect; classic models use valve amplifiers. The swirling sound paired with the Hammond organ, and often put on guitars and vocals too.
