The Good Vibes recaptures the iconic chorus/vibrato effect of the 1960s in an updated pedal with features designed to meet the needs of the modern player. Like the original Uni-Vibe®, it uses photocells to create chorus and vibrato with a warm, undulating, liquid groove for a sound and response that’s 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! - Selectable Chorus or Vibrato delivers classic 1960's tone and vibe - Simple control set: Volume, Intensity, Speed - Expression pedal control of Speed or Intensity - Boosted power rails for extended headroom and definition - Always-on Speed indicator - Rugged and compact die-cast chassis - True Bypass - EHX 9.6DC power supply included
