The Fender Vibratone, produced from 1967 to 1972, is a rotary speaker cabinet designed to emulate the swirling, Doppler-based effects of a Leslie speaker in a more compact and guitar-friendly format. Based on the Leslie Model 16, the Vibratone featured a 10-inch speaker firing into a rotating 15-inch Styrofoam drum powered by an electric motor. The rotation created a Doppler effect, resulting in rich, modulated sounds ranging from shimmering choruses at slow speeds (40 RPM) to warbling tremolo effects at fast speeds (340 RPM). A two-button footswitch allowed players to toggle between speeds and enable or bypass the effect. Though initially overshadowed by its larger Leslie counterparts, the Vibratone became a staple for psychedelic rock and remains highly valued for its unique tonal character.
The Vibratone's versatility allowed for a range of effects:
The Fender Vibratone remains a highly sought-after piece of gear for its ability to create lush, rotating speaker effects in a compact format. Its association with legendary players like Stevie Ray Vaughan and David Gilmour cemented its place in music history. While original units are rare and expensive today, its sound lives on through modern rotary speaker simulations in pedals and digital platforms.
