This is the DIGITECH WHAMMY CHROME! The Whammy 4 Chrome version, limited to 1000 units worldwide, was recently released to commemorate its 20th anniversary! The Whammy pedal was released as a pedal-operated intelligent pitch shifter! Extreme pitch changes from ±1 to 2 octaves and 3 octaves down create a tricky sound that is more than arming, even on guitars without arms! Almost as new with no signs of use! Comes with box and adapter. International Buyers – Please Note. Thank you for your understanding.
