ongratulations, and thank you for your purchase of the Digitech XP-400 Reverberator. The XP-400
offers a unique opportunity to add several different reverb types including Spring tank, Plates, Reverse and
many others to a great sounding amplifier that may not have an existing reverb unit. In addition to these
reverb types, the XP-400 also has a chromatic tuner for quick tunings on stage or in the studio and can act
