Uni-Vibe

The Shin-Ei Original Uni-Vibe is a classic phase shifter effect pedal, originally designed by Fumio Mieda in the 1960s. This pedal was first marketed as the Vibra-Chorus and is known for its ability to replicate the sound of atmospheric modulation, providing a distinctive chorus and vibrato effect suitable for electric organ and guitar. Musically, the Uni-Vibe produces a thick, rich sound that has become a defining characteristic in classic rock. Its unique circuitry, featuring a metal hood and incandescent bulb, contributes to its signature tonal qualities. The pedal includes an external speed control foot pedal, allowing players to adjust the modulation effect with precision.
