Check the listing for details. Electro-Harmonix Bad Stone Phaser. Condition: New. Listed at 113.67 USD. EHX has resurrected the legendary Bad Stone Phase Shifter. As prices for the old Bad Stones from the 1970s have skyrocketed, now's your chance to get a new edition that stays true to the original circuit design and three-button control layout, but offers current improvements for the modern player. The Bad Stone offers an incredible six levels of phase shift, as well as a manual mode that allows the player to freeze the phase. The Rate knob controls the speed of the phase shift, which ranges from a very slow noise to a fast, oscillating warble. Feedback determines the depth of the phase effect and a toggle switch allows you to choose between Auto and Manual modes. All of our items have a 30-day return policy without explanation.
