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
as a volume controller.
This owner’s guide is provided to get you up and going with the XP-400 and use it to its full potential.

11. MODE/(Hold)PROGRAM - This button is used to put the XP-400 in and out of User mode. The beauty of

the the User mode is, that the XP-400 will give you the opportunity to store up to 6 of your favorite fac­tory programs in the same area. This will save you the toe-tap dancing ritual of accessing programs.
This button is also used to calibrate the noise gate threshold of the XP-400. To put the XP-400 in User
mode, simply press the <MODE/(Hold) PROGRAM> button.

To store a Factory program as a User program, the procedure is as follows:

display will flash:

location. Now just press the <MODE/(Hold)PROGRAM> button to save. The display will read:

SA

When the XP is in Bypass mode, the Expression pedal is inactive, but programs can still be selected using

mode is exited. When the XP is in bypass mode, the display will read:
