Rotary Mod is a rotating cabinet effect that simulates a Leslie speaker. Just like the original sound derived from the uber-famous Hammond organ’s Leslie speaker cabinet, the plug-in produces a pulse-like vibrato effect dependant on the speed of rotation. Rotary offers precise control to dial in the exact amount of movement you need. This classic, swirly effect has been used on countless hit records to drastically transform guitars, bass, synths, and even vocals. Notably used by The Beatles, Beach Boys, Cream, and Pink Floyd, this iconic emulation brings that classic ’60s whirling modulation bliss into the 21st century and the palm of your hand.
