Electro Harmonix BAD STONE

This analog phase shifter is a recreation of EHX's legendary pedal from the 1970's, but with a few modern improvements. The Bad Stone delivers an incredible six stages of phase shifting plus a manual mode that lets the player freeze the phase. Its Rate knob controls the phase shifting speed which goes from a very slow swoosh to a rapid, oscillating warble. Feedback determines the depth of the phase effect and a toggle switch lets the user select Auto or Manual modes.
