Expression Assign

The GNX3 has several options for real-time control over effects parameters in each of its presets.
Parameters can be modified during performance both manually and automatically by several methods. These
are referred to as expression controllers and include the following: the built-in Expression Pedal, Internal
LFOs (low frequency oscillators), and the Control Footswitch. Each of these controllers can be programmed
specifically for each preset, giving you many options for manipulating each in a different manner.

Expression Pedal

The Expression Pedal on the GNX3 can control up to 3 parameters in real time. Each parameter assigned
to the Expression Pedal can have specific ranges of how much the parameter is controlled by using the
minimum and maximum controls. The GNX3's Expression Pedal includes DigiTech's exclusive V-Switch.
The V-Switch lets you switch the Expression Pedal assignment on the fly. Apply extra pressure to the toe
of the Expression Pedal to engage the V-Switch, and the Expression Pedal switches between the assigned
parameter and the Wah. The sensitivity or amount of pressure required to engage the V-Switch can be
adjusted to suit your personal taste (or weight of your foot). See page 66 for the V-Switch Sensitivity
adjustment procedure.
The procedure for assigning a parameter to the Expression Pedal is as follows:
1. Press the Effect Select button until the Exp Assign row has been selected.
2. Press the Status button until the display reads
(Expression Pedal Link 2), or
you want to use or the number of parameters you intend to assign.The display alternates between the
Expression Pedal selection and the assigned parameter.
3. Rotate the Parameter 1 knob until the parameter appears in the display. See the Expression Parameter
Assignment List on page 38 for a complete list of assignable Parameters.
4. Rotate the Parameter 2 knob to select the minimum value the parameter reaches with the Expression
Pedal in the toe up position (not available when volume is the assigned parameter).
5. Rotate the Parameter 3 knob to select the maximum value the parameter reaches with the Expression
Pedal in the toe down position (not available when volume is the assigned parameter).
6. Store your Expression Pedal assignment to your preset. See page 17 for more information on the
storing procedure.

LFOs

The GNX3 includes two low frequency oscillators (LFO1 and LFO2) that can be assigned to the
Expression Pedal parameters. A low frequency oscillator automatically varies the value of the assigned
parameter at a steady rate. A minimum and maximum value can be assigned. For instance: if the Amp
Gain was assigned to LFO1, and the minimum value was set at 1 and the maximum value was set at 99,
the GNX3 would automatically sweep the amount of distortion from clean to distorted and back to
clean. Individual LFO speeds can also be assigned. In the previous example, the LFO speed would
determine the length of time it took the LFO to sweep from the clean to the distorted sound. The
procedure for assigning the LFOs in the GNX3 is as follows:
1. Press either EFFECT SELECT button until the Exp Assign row is selected.
2. Press the STATUS button to assign LFO1 (
3. Rotate the Parameter 1 knob until the Parameter is displayed. See the Expression Parameter
Assignment list on page 63 for a complete list of assignable Parameters.
4. Rotate the Parameter 2 knob to select the minimum value the assigned parameter reaches at the
