The Presets
Presets are named and numbered locations of programmed sounds which reside in the Vx400. Presets are
recalled with the footswitches. The active effects in each preset are indicated by the lighted LED's in the
Effect Matrix. The Vx400 comes with 40 User Presets (Presets 1-40), and 40 DigiTech factory presets (41-
80). The User Presets are locations where you can store your edits. You may not store changes to the
Factory Presets. From the factory, the 40 User Presets are exact duplicates of the 40 Factory Presets.
Performance
When you first apply power to the Vx400, it powers up in Performance mode. Performance mode provides
access to all of the presets within the Vx400 via the Up and Down Footswitches. The Number 1 Knob (left)
adjusts the Bass, the Number 2 Knob (second from the left) adjusts the amount of Midrange enhancement,
the Number 3 Knob (middle) adjusts the Mid Frequency, the Number 4 Knob (second from the right) adjusts
the amount of Treble (high frequency) enhancement, and the Number 5 Knob (right) adjusts the Master Level
(volume).
Bypass
The Vx400 Presets can be bypassed for clean, unprocessed vocals and instrument signals. To bypass the
Vx400, press the
BYPASS
Footswitch. The display will read Bypass indicating the preset is bypassed.
Pressing the Up or Down Footswitches advances to the next available preset. Pressing the Bypass
Footswitch again exits you from Bypass and loads that preset.
Tuner
The Tuner lets you quickly tune or check the tuning of any instrument plugged into the Vx400. Enter Tuner
mode by pressing and holding the Up and Down Footswitches simultaneously. The display briefly shows
tuner
indicating that you are in Tuner mode. To begin tuning, play a note on your instrument (a harmonic at
the 12th fret usually works best for guitars). The right 2 characters in the display shows the note being
played. The left characters in the display indicate whether you are sharp or flat. Arrows pointing to the left
(

) indicate the note is sharp and should be tuned down. Arrows pointing to the right (

note is flat and should be tuned up. When the note is in tune, the display shows
--><--
.
In Tuner mode, you can change your tuning reference. The default factory setting is A=440 Hz. (displayed as
A=440). Rotate the Number 1 Knob to select alternate dropped tunings. Alternate tunings are A = Ab , A =
G , and A = Gb. The display window briefly flashes the selected tuning preference.
The output is muted in Tuner mode. The Expression Pedal returns sound to the output allowing signal to be
heard while tuning. Exit tuner mode by pressing any of the 3 Footswitches.
