SERIES ROTO - ROTARY SPEAKER SIMULATOR

Before we even mention the Uni-Vibe, we have to bring up the object it was created to model, the Leslie Rotating Speaker. Originally, Don Leslie figured out how to get the Doppler sound effect into a wooden cabinet in the 1930s, and guitarists worldwide sought a way to get that sound into an effects box. The Uni-Vibe came out in that creative era of the 60s, and even though it was not considered a “successful” model of the Leslie speaker, it came to be known for its fresh, unique vibe and found a place in rock and roll history by its own right.
