The Drybell Vibe Machine Chorus Vibrato summons the classic tones of the '60s surf rock tube amp effects in a convenient pedal that's easy to use. Sporting two knobs for intensity and speed and switches for normal/bright and chorus/vibrato modes, you can go from a slight wave to a throttling pulse. One of the best emulations of the original Univibe, this ultra-compact rendition is pedalboard friendly and packed with possibility.
