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 fac-
tory 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:
First, select the Program to be stored. Press and hold the <MODE/(Hold)PROGRAM> button. The
display will flash:
U1 . From here, use the <UP/(Hold)DOWN> footswitch to select which user
location. Now just press the <MODE/(Hold)PROGRAM> button to save. The display will read:
SA to confirm, then return to Program mode.
12. AC Line Input - Connect the power adapter here. Use only the enclosed PS 750 power supply.
Tuner Mode
To access the Tuner mode, press and hold the <BYPASS/(Hold)TUNER> footswitch until tu appears in the
display.
T he currently played note is displayed in the left character of the status display window, while the
intonation is displayed in the RIGHT character of the window.
When the input note is in tune, the display will read:
When the note is flat, the intonation character will rotate counter clockwise as shown:
When the note is sharp, the intonation character will rotate clockwise as shown:
The faster the character spins (either clockwise or counter clockwise), the more out of tune the note is.
Bypass Mode
To place the XP-400 in bypass mode, press the <BYPASS/(Hold)TUNER> footswitch once.
When the XP is in Bypass mode, the Expression pedal is inactive, but programs can still be selected using
the <UP/(Hold)DOWN> footswitch while the unit is in bypass. The new program is loaded once Bypass
mode is exited. When the XP is in bypass mode, the display will read:
Factory Reset/Pedal Calibrate
To reset the User programs to their factory settings and calibrate the expression pedal, press and hold the
<BYPASS/(Hold)TUNER> foot switch and apply power to the unit. Wait until the letters
rS appear in the
display and release the foot switch. The display will now read:
Pd and CA , indicating that you are in
Pedal calibrate mode. Once
Pb appears, rock the pedal back and press the <BYPASS> foot switch. When
PF appears, rock the pedal forward and press the <BYPASS> foot switch. SA will next appear in the dis-
play to confirm the pedal is now calibrated.
