The Voodoo Lab Micro Vibe delivers the lush, psychedelic swirl of the original Uni-vibe. And it’s the only Uni-vibe copy available in a compact, battery-operated pedal. The Micro Vibe includes the original sine-wave oscillator, incandescent lamp, and photocells to achieve the most authentic sound of any Uni-vibe clone.
