Eventide Audio’s new Riptide pedal is the result of research into the Shin-ei Uni-Vibe overdrives. The Riptide features two classic effects offered with the pedal as “vibe” and “drive.” The two colors of balanced, touch-sensitive overdrive distortion are green for a dynamic mid-range crunch and red for a smooth and boosted overdrive sound. The green for vibe captures the modulation of the original Uni-Vibe and enhanced stereo output. Red offers a deeper, more phase-y effect. Players can reorder the process from drive into vibe or vibe intro drive, and any combination of parameters can be mapped to an expression pedal. Three knobs for drive, three for vibe and a pair of dual-action latching or momentary footswitches provide players effect control, with five onboard presets and more available using Eventide Device Manager software.
