Featuring switchable vibrato and chorus modes, a voice knob controlling delay time for a wide spread of choral effects and a bright/dark switch for even more tonal options, the Red Witch Empress is one of the most expansive chorus/vibrato pedals on the market. A multi-foliate effect capable of summoning sparkling shimmer or undulating waves of sound with a flick of a knob, this pedal easily adds new soundscape facets to post-rock, a surf-y tinge to garage, or washing swells to psychedelia.
