Works great. Pro features like Expression pedal input and tap tempo. Can copy most of the classic phasers out there plus has a very unique "Step Phaser" effect that is similar to the sound Zappa gets on his guitar solo in "Ship Ahoy" (which I think is a sample and hold module like the Oberhiem Voltage Control or Maestro FSH-1, similar to some sounds the ZVex Ooh Wah II makes).
