EHX Good Vibes Modulator pedal
Like the original Uni-Vibe, it uses photocells to create chorus and vibrato with a warm, undulating, liquid groove for a sound and response thats true to the classic design. Boosted power rails provide 21st century definition and headroom, and an expression pedal input puts free-form control for speed or intensity at your feet. True bypass, too. Very groovy!
