The new circuit perfectly replicates the physical phenomenon on which the analog sound is based, with a mix of chorus ,phaser, tremolo and rotary. You can switch between Chorus or Vibrato mode by holding the button down: in Chorus mode the Phaser mixes with the dry signal to create a Rotary effect, while in Vibrato mode there is a pitch modulation. Both modes offer a vibe effect with a strong vintage flavor at each chosen setting.
