I worked on the development of the first prototype of this pedal with Mike Beigel.  Electro Harmonix really got it right when they put this one into production. This is a great pedal. A pedal for the ages.

Pedal Features:

• Extreme rate control ( Min.= 14 seconds, Mid.= 1 second, Max.= 29.5 Hz ).
• Stereo output for huge panoramic phasing.
• Optical circuitry
• Start and Stop controls to dial in that sweet spot.
• LFO shape switch ( triangle and square ).
• Envelope phasing.
• Improved die cast case.
• Power supply included.
• Optional control pedal.
