Used JHS Unicorn in great condition. the Unicorn Uni-Vibe offers the classic tone of a bulb-driven Uni-vibe effect with the added magic of tap tempo control over the LFO. Like other tremolo-style effects, you get Volume, Depth, Speed, and Ratio controls along with a toggle between wet and dry settings. This pedal has minimal dings in scratches from use, but otherwise functions as it should. Original box not included.
