Voodoo Lab"s Micro Vibe pedal delivers the same juicy, swinging tone as the original 1968 Uni-Vibe. Its unique sound achieved legendary status when Jimi Hendrix used the effect on his Band of Gypsys record, and his landmark Woodstock performance of "The Star Spangled Banner." Guitar heroes like Robin Trower, David Gilmour, and Stevie Ray Vaughan also helped make the phase-based effect a tone classic. Completely analog, Micro Vibe features the same sinewave oscillator, incandescent lamp, and photocells, which gave the original its groovy swagger. Thanks to the tone guru"s at Voodoo Lab, Micro Vibe gives you the same lush, psychedelic colors of the original, but in an ultra-compact, pedalboard friendly 9V stompbox! Micro Vibe features true bypass switching, a heavy-duty metal switch, and on/off status LED.
