This pedal is a faithful replication of the historical Uni-Vibe® foot controller function. Uni-Vibe® Foot Control pedal allows you to transfer the Speed and Effect/Bypass controls from the main unit to the foot controller. When the pedal is plugged into the Pedal Jack on the UV-1's back panel. rocking all the way back sets the Uni-Vibe to bypass (no effect). Rocking forwards turns the effect on and increases the speed.

Features: Heavy die-cast zinc housing. a 10-million cycle industrial-grade microswitch. and a high-quality connection using standard stereo guitar cables.
