The Versa Vibe takes a classic effect and adds more controls to give THE most VERSAtile vibe pedal on the market today. Controls such as Bass Throb, Wet-Dry, and Waveform allow near limitless tonal options! Add in features like true bypass switching, optical technology and internal trim-pots and the Versa Vibe will blow you away.This item is hardly used. Works perfectly! Has some signs of cosmetic wear, but has spent all of its time on a pedal board. This is the best sounding chorus/vibrato pedal I've ever used.
