The Sixties Vibe is an exact rendition of the original Univibe pedal which uses 4 photocells surrounding a pulsating light source to deliver its very unique and recognizable sound - a thick chorus/vibrato type of effect, starting off with a slow, watery swirl and gradually becoming more 'alive' as the onboard speed knob is manipulated counter-clockwise, resulting in a 'machine-gun' type warble around the 9 o'clock setting. An excellent choice for all the Hendrix / Trower / Floyd fans out there!
Adaptor spec: 18VDC @ 150mA, center-negative
