The rotary effect was one of the earliest modulation effects to appear on the music scene. Originally designed for the Hammond Organ, the Leslie Speaker™ creates the famous Doppler Effect (church organ-like sound) with its rotating speaker. This rotary sound can be heard on everything from The Beatles' "It's Only Love" to Stevie Ray Vaughan's "Cold Shot," John Mayer's "City Love," and Soundgarden's "Black Hole Sun." It's a truly ubiquitous classic! The 3 Series Rotary Chorus brings you this classic rotating chorus tone in an affordable and easy-to-use pedal format.
