Introduction Introduction The DigiTech GNX2, is the most advanced guitar processor of its kind. Thanks to the highly advanced technology provided by GeNetX™, and the extreme horsepower contained in the Audio DNA™ DSP engine, you now have the tools to literally create your own guitar amplifier and speaker cabinet models. All of this power lets you create a sound that is your own. In addition to designing models, the GNX2 has a library full of studio quality effects.
Introduction Quick Start The Quick Start section is included for those of you who would rather play now and read later. Making Connections Connect your instrument to the INPUT jack on the rear panel. Connect the LEFT/RIGHT OUTPUTS to the input(s) of your amplifier(s), power amp, or mixer. Apply Power Turn the OUTPUT knob on the rear panel of the GNX2 all the way down (fully counter clockwise). Connect the plug of the PSS3 power supply to the POWER jack on the GNX2.
Introduction A Guided Tour of the GNX2 The Front Panel 1. Footswitches 1- 4 Depending on the selected mode, these 4 footswitches select presets, change amp channels, and turn individual effects on and off. Bypass, accesses the Tuner, or controls Learn-A-Lick functions. 2. Matrix The Matrix LEDs light identifying the active effects for the selected preset in performance mode, or the selected row of effects in edit mode. 3.
Introduction 6. Display The display consists of eight green alpha-numeric characters, and two red numeric digits. The display provides information for several different functions depending on the selected mode. In Performance mode, the display shows the selected preset name and number. The display also shows bank names when changing banks, and momentarily flashes the active amp channel when the amp channel is changed.
Introduction these footswitches move through the User Preset Banks. In Learn-A-Lick™ Mode, these footswitches select the playback speed of the sampled phrase. 10. Expression Pedal The Expression Pedal controls effect parameters in real time. Most GNX2 parameters can be assigned to the Expression Pedal. Applying extra pressure to the toe of the Expression Pedal switches between controlling the assigned parameter(s) and controlling the Wah.
Introduction The Rear Panel 1. Mic Output This XLR jack passes your mic signal to the house mixing console. 2. Mic Input This XLR jack connects a low impedance mic to the GNX2 that can be used with the Talker and Vocoder effects. A mic with a cardioid pattern is recommended. 3. Input Jack Connect your instrument to this jack. 4. Jam-A-Long Jack Use a 1/8” stereo plug to connect this jack to the output of a tape or CD player. This lets you play along with the music, or record a musical passage. 5.
Introduction 12. MIDI In This jack receives all incoming MIDI data. Connect this jack to the MIDI out of a computer, sequencer, MIDI controller, or MIDI storage device. 13. MIDI Out/Thru This jack sends MIDI data from the GNX2. Connect this jack to the MIDI in of a computer, or external MIDI recording device. When enabled, MIDI Thru sends the same information the GNX2 received at the MIDI In. 14. Strain Relief This secures the power cord and to help prevent it from disconnecting during a performance.
Introduction Direct to a Mixing Console The GNX2 can be connected directly to the inputs of a house PA system, or a recording console. 1. Connect the guitar to the GNX2’s input. 2. Connect the GNX2’s outputs to the channel inputs of the mixing console. 3. If the GNX2 is to be used in Stereo mode, set the pan controls of the mixer hard left and right, and select Stereo as the output mode from the Utility menu. See page 40 for more information on the Output mode.
Introduction About the GNX2 The Presets A preset is a named and numbered location of a programmed sound that resides in the GNX2. Presets can be recalled with the FOOTSWITCHES or the DATA WHEEL. The GNX2 comes with 64 Factory and 64 User presets. The Factory Presets do not let you store changes to them. The User presets let you store changes. From the factory, the 64 User presets are exact duplicates of the 64 Factory presets.
Introduction 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.
Introduction Learn-A-Lick Mode The Learn-A-Lick function allows you to record a 9 second passage of music and play it back as slowly as 1/4 the original speed with no change in pitch. This is very useful for picking out the notes of a fast guitar solo. There are 6 Learn-A-Lick functions.
Introduction Pattern Press the STORE (Pattern) button to adjust the drum pattern. The selected drum pattern is shown in the display. Use the DATA WHEEL to select a new pattern.
Editing Functions Editing Functions Editing/Creating a Preset The GNX2 was designed to make the process of sound creation easy and intuitive. Because the GNX2 provides both Amp Modeling and Effects Processing, the editing functions have been divided into two sections: the Amp/Cabinet Modeling section and the Effects section. The GeNetX™ technology contained in the GNX2 allows you to go much further than mere Amp Modeling.
Editing Functions Selecting Amp/Cabinet Models The first step to editing an Amp Model, Cabinet Type, or creating your own HyperModel™ is to select the Amp and Cabinet types for the Green and Red Amp channels in your preset. To do this, the GNX2 must be in the Performance mode, indicated by the Status button’s LED lighting yellow. EXIT returns you to Performance mode regardless of the selected mode. The procedure for selecting an Amp Model or Cabinet Type for the Green or Red Amp Channels is as follows: 1.
Editing Functions Creating HyperModels™ Creating new, unique HyperModels™ is what GeNetX™ is all about. Once the Green and Red Amp Models and Cabinet types are selected, and the Amp Parameters and Cabinet Tuning have been adjusted, GeNetX™ technology lets you do something amazing. The characteristics of each Amp and Cabinet assigned to the Green and Red Channels can actually be combined or “Warped” to create a completely new Amp HyperModel™.
Editing Functions Rotating the parameter knobs increases or decreases the value of the parameter and you hear the change in real time. When parameter values have changed, the Store LED lights indicating the preset has been modified and needs to be stored (see page 16 for more on the store procedure). Changing presets, or turning the power off before storing any changes will erase your changes and revert to the stored values.
Editing Functions 7. Press the STORE button again to finish. To copy one preset to another preset location, begin by selecting the preset you want to copy, then follow the steps listed above. Press EXIT at any time during the procedure to aborts the process.
Effects and Parameters Effects and Parameters The GNX2 can be thought of as several different “virtual” amplifiers, and individual, hi-tech stomp boxes. With stomp boxes, the order in which they are connected can make a big difference in how good the overall sound is. Whether the stomp boxes are placed before the amp, or in the amp’s effects loop will also make a difference. The GNX2 has the effects connected in the most logical, and best sounding order.
Effects and Parameters For instance, a Ratio of 4 to 1 means that a signal exceeding the Threshold by 4 dB will only be allowed 1 dB of increased output. Higher settings yield a tighter, sound and increase sustain. Lower settings allow better dynamics. Ranges include: ¡2-1 (1.2:1), ¡5-1 (1.5:1), ¡8-1 (1.8:1), ™0-1 (2:1), ™5-1 (2.5:1), £0-1 (3:1), ¢0-1 (4:1), ∞0-1 (5:1), •0-1 (8:1), 10-1 (10:1), 20-1 (20:1), and INF-1 (infinity:1). Threshold - The Number 3 knob selects the Threshold (threshld).
Effects and Parameters Pitch Shifter. Interval choices include: OCT 7TH 6tH 5tH 4tH 3RD 2ND DowN DowN DowN DowN DowN DowN DowN (octave down) (a seventh below) (a sixth below) (a fifth below) (a fourth below) (a third below) (a second below) 2ND 3RD 4TH 5TH 6TH 7TH OCT UP UP UP UP UP UP UP (a second above) (a third above) (a fourth above) (a fifth above) (a sixth above) (a seventh above) (an octave above) Parameter 2 (IPS) - The Number 3 knob selects the scale the IPS will use.

Ranges from L 99 to R 99.
Effects and Parameters TRIGGERED FLANGER (TRiGFLnG) A Triggered Flanger is the same sound as a regular Flanger but it lets you choose the starting point of the Flanger sweep. With a regular Flanger, the low frequency oscillator (LFO) is continually sweeping up and down. Meaning, when you begin to play, the flanger may be at the top, bottom, or any random point of the sweep.
Effects and Parameters PANNER ( Panner) An Auto Panner modulates the sound from left to right at an even rate. Parameter 1 - The Number 2 knob adjusts the rate (Speed) at which the signal pans from side to side. Ranges from 1 to 99. Parameter 2 - The Number 3 knob adjusts the intensity (Depth) of the changing pan. Ranges from 0 to 99. Parameter 3 - The Number 4 knob selects the type of wave form the modulation will use. Choices include: Triangle , Sine, and Square.
Effects and Parameters Parameter 2 - The Number 3 knob adjusts the intensity (Depth) of the AutoYa™ effect. Ranges from 1 to 99. Parameter 3 - The Number 4 knob adjusts the throaty quality (Range) of the AutoYa™ effect. Ranges from 1 to 50. * Parameter 4 - Adjusts the left to right balance of the wet signal. Ranges from L 99 to R 99. Mod Mix - The Number 5 knob controls the mix (mod mix) of wet and dry signal. Ranges from 0 (all dry) to 99 (all wet).
Effects and Parameters Parameter 3 - The Number 4 knob adjusts the left/right balance (BAL) of the Wah signal. Ranges from left -99 (L-99) to right 99 (R+99). Mod Mix - The Number 5 knob controls the mix (mod mix) of wet and dry signal. Ranges from 0 (all dry) to 99 (all wet). DETUNE (DetUNe) A Detuner makes a copy of your incoming signal, takes the copied signal slightly out of tune from the original, and mixes the two signals together.
Effects and Parameters Time - The Number 2 knob adjusts the length of time between repeats. Ranges from 10 MS through 2000MS (10 through 2000 milliseconds) in 10 ms increments. Using the Data Wheel while the Delay Time is showing in the Display will adjust the Delay Time in 1 ms increments. Feedback - The Number 3 knob adjusts the number of times the delayed signal will repeat (feedback). Ranges from 1 to 99 and rpt hold (infinite repeat).
Tutorial Tutorial Suppose you wanted to create your own HyperModel™ that incorporated the sweet tones of a vintage Tweed using an American 2x12 cabinet, and the ripping distortion of a Rectified Amp with a British 4x12 cabinet.
Tutorial Adjust the Green Channel Parameters The Tweed amp that we selected for our Green Channel assignment uses the factory default settings for the Gain, EQ, and Level Parameters.Therefore, you may want to change the settings. To access the Green Channel Parameters, press the STATUS button. All horizontal LEDs light green indicating that all 5 knobs will adjust the Green Channel Parameters. Rotate the Number 1 knob to adjust the Tweed Gain. Rotate the Number 2 knob to adjust the Tweed Bass.
Tutorial Tune the Cabinets (optional) You may also want to adjust the resonance for the American 2x12 and the British 4x12 Cabinets. To access the Cabinet tuning for both Red and Green Channels, press and hold the STATUS button until the display reads CAB TUNe (Cabinet Tuning). Release the Status button and rotate the Number 2 knob to adjust the tuning for the Green Cabinet (gtune º0) and the Number 5 knob to adjust the tuning for the Red Cabinet (rtune º0).
Tutorial Select Models for the Preset’s Channels In the previous steps, we selected a Tweed for the Green Channel and a Rectified Model for the Red Channel.Then we Warped the two together to create our HyperModel™.This HyperModel™ is saved as an amp type that we named Rectweed, but it is not currently part of our preset. In this example preset, we need to be able to toggle between an acoustic guitar simulation and our new HyperModel™.
Tutorial Turn the Compressor Off We don’t want to use compression in our preset so, we need to turn the compressor off. Press the EFFECT SELECT DOWN button. The Compression LED lights and the display shows the current status of the Compressor. If the Compressor is on, press the STATUS button until the red display reads off (Of). Turn the Whammy™/IPS Off We don’t want any Whammy™ or IPS effects in this preset. Press the EFFECT SELECT DOWN button, and the Whammy/IPS LED is lit.
Tutorial Adjust the Noise Gate For our example, we want our Noise Gate to open quickly with a relatively weak signal.This type of gate uses the Silencer™ with a low Threshold and short Attack Time. Press the AMP FOOTSWITCH to select the Red Amp Channel. Press the EFFECT SELECT DOWN button and the Noise Gate’s LED lights. If the display reads off (Of), press the STATUS button until the display reads on (On). Rotate the Number 1 knob until the display reads SILeNCeR for the type of gate.
Tutorial Turn the Delay Off In our example preset we want to bypass the Delay. Press the EFFECT SELECT DOWN button again and the LED in the Delay row will light. If the display reads on (On), press the STATUS button until the display reads off (Of). Select and Adjust the Reverb In our example preset we wanted a little bit of Hall Reverb to provide some ambience. Press the EFFECT SELECT DOWN button again and the LED in the Reverb row lights.
Tutorial Once the Display reads exampLE, press STORE again.The numbers in the red numeric display are flashing. Using the Data Wheel, select 64 as the destination. Press STORE once more to save the preset. Congratulations! You have successfully created a Preset.
