The Footswitches
The GNX2 1-4 footswitches are primarily used to select presets or turn on and off effects, depending on
which mode is selected. However,these footswitches are also used to access other GNX2 functions. For
example, pressing Footswitches 1 and 2 simultaneously,or pressing the lit Footswitch (in Preset mode)
bypasses the the current preset. Pressing Footswitches 2 and 3 simultaneously accesses the Tuner mode.
Pressing Footswitches 3 and 4 simultaneously activates the Learn-A-Lick mode. In Learn-A-Lick mode,
Footswitches 1-4 control various Learn-A-Lick functions.
The Expression Pedal
As you go through the different presets in the GNX2,you will find that the expression pedal has different
functions.The Expression Pedal can control three different parameters in each Preset. Rock the
Expression Pedal back and forth to change the values of the assigned parameters. The pedal can control
assigned minimum and maximum values (stop points) for each parameter. The Expression Pedal also
includes a feature called V-Switch that allows you to override the Parameters assigned to the Expression
Pedal and replace them with the Wah effect. See page 37 for more information on assigning the
Expression Pedal.
Bypass Mode
The GNX2 presets can be bypassed for a clean,unprocessed guitar tone. Bypass mode turns off all
effects and modeling. To bypass the GNX2 in Preset mode,press the active preset’s Footswitch (the 1-4
footswitch that is lit),or press Footswitches 1 and 2 simultaneously. To bypass the GNX2 while in FX
Mode, press Footswitches 1 and 2 simultaneously. When the GNX2 is bypassed,the display reads
BYPASS and all LEDs in the matrix are off. Press any Footswitch to exit Bypass and return to the last
preset. The Matrix and Programming buttons are not available in Bypass mode.
Tuner Mode
The Tuner in the GNX2 lets you quickly tune or check the tuning on your guitar. Press Footswitches 2
and 3 simultaneously to enter Tuner mode. The display briefly flashes
TUNER.To begin tuning,play a note
on your guitar (a harmonic at the 12th fret usually works best).The red numeric display shows the note
being played,and the green alpha-numeric display indicates whether the note is sharp or flat. Arrows to
the left (
<<<) indicate the note is sharp and should be tuned down. Arrows to the right (>>>) indicate
the note is flat and should be tuned up. When your note is in tune,
-><- is displayed.
In Tuner mode,you can set your tuning reference with the Data Wheel. The default factory setting is
A=440 Hz. The tuning references range from 427 Hz to 453 Hz (± 50 cents (1/2 semitone) from either
direction of 440 Hz). Below 427 Hz, are alternate dropped tunings. The alternate tunings are
REF Ab
(A=Ab),
REF G (A=G),and REF Gb (A=Gb). The display window briefly flashes the selected tuning pref-
erence.
Exit tuner mode by pressing any of the Footswitches.
Jam-A-Long
The Jam-A-Long feature lets you connect a Tape, CD, or MP3 player to the GNX2. The tape, CD,or MP3
player’s signal is output through the GNX2’s left,right, and headphone outputs. To use the Jam-A-Long
feature, connect the headphone output of your player to the JAM-A-LONG INPUT on the rear panel
of the GNX2. Use a 1/8” stereo cable, and press play on your Tape,CD,or MP3 player.
