Pitch shift vibrato in a pedal? I had a univibe clone, and I was in love with the vibrato side. I am looking for a tremolo/vibrato pedal that can do the detune-warble thing to the signal, not necessarily a univibe. Is that sound exclusive to the opto-style univibe? I have tried "the clone theory" and chorus-vibrato is not what I want. I want dry, non-delayed, pitch shift vibrato.
