  • Page 18: Editing/creating A Preset, Amp/cabinet Modeling, Editing Amp Models And Cabinet Types

    Editing Amp Models and Cabinet Types Each Preset in the GNX1 is equipped with a Green, Red, and Yellow (Warped) Amp Channel.The Green and Red Amp Channels include individually assignable Amp Models, Cabinet Types, Gain, EQ, and Level settings.The Speaker Cabinet can also be tuned meaning that you can select the Cabinet’s resonant frequency.

  • Page 19: Selecting Amp/cabinet Models, Adjusting Amp Parameters

    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 GNX1 must be in the Performance mode which is indicated by the LED next to the Status button lighting yellow.

  • Page 20: Cabinet Tuning

    Warping the Green and Red Amps together is as follows: 1.With the GNX1 in Performance mode (indicated by a yellow Status LED), rotate the Parameter 3 knob to Warp the Green and Red Amps and Cabinets together. Rotating counterclockwise will add more of the Green Channel characteristics, and clockwise will add more of the Red Channel characteristics.

  • Page 21

    4. Repeat steps 2 and 3 until the desired HyperModel™ name is shown in the Display. 5. Press the Amp Save button again to select one of the 9 User HyperModel™ locations. If the GNX1 has any unused HyperModel™ locations available, the Display will read EMPTY U1.The U1 will be flashing indicating that this is the first available location for your new creation to be stored.

  • Page 22: Editing The Effects

    UNCTIONS Editing the Effects The GNX1 contains a comprehensive library of fully programmable, studio quality Effects. The Effects section is accessed with the Effect Select Up/Down buttons.The Matrix LEDs will light one at a time to indicate the selected Effect row.When you have selected the desired effect row, you have up to 5 Parameters which can be edited. Each effect row has been divided into 6 columns of Parameters.The first column is the on/off control for the selected effect.

    Compressor in order to achieve unity gain. It is possible to clip other effects in the GNX1 by setting the Compressor Gain too high. Ranges from 0 to 20 (dB). The Number 5 knob has no function when the Compressor is selected.

  • Page 26: Noise Gate

    Equalization is an extremely useful tool used to further shape the tonal response of your guitar signal.The EQ in the GNX1 is similar to the tone knobs on an amplifier with the exception that the GNX1 allows you to choose the center frequency for the Mid Range and Treble adjustments.

  • Page 27: Chorus/mod Effects, Chorus, Flanger, Phaser, Triggered Flanger

    ECTION HREE FFECTS AND ARAMETERS Chorus/Mod Effects The Modulation Effects row is a multi-function module allowing you to select effects such as; Chorus, Flanger, Phaser, Triggered Flanger,Triggered Phaser,Tremolo, Panner,Vibrato, Rotary Speaker, AutoYa™, YaYa™, SynthTalk™, Envelope Filter (auto wah), Detune, and Pitch Shift. Only one of the effects in this row can be used at a time.When the Chorus/Mod row is selected, the Status button is used to turn the Effect module on (EFF ON) and off (EFFOFF).The Number 1 Knob is used select the type of Effect to be used.

  • Page 28: Triggered Phaser, Tremolo, Panner, Vibrato, Rotary

    ECTION HREE FFECTS AND ARAMETERS Triggered Phaser (TRGPHA) A Triggered Phaser is the same sound as a regular Phaser but allows you to choose the starting point of the Phaser sweep. In a regular Phaser, the low frequency oscillator (LFO) is continually changing the phase of the signal. This means that when you begin to play, the phaser may be at the any random point of the phase.With a Triggered Phaser, every time the signal exceeds the Sensitivity level setting, the Phaser will begin at the point of phasing that you designate with the value of the LFO Start Parameter.

  • Page 31: A Guided Example, Choose A Preset, Select The Green Channel Amp And Cabinet

    For this example, we are going to use a vintage Tweed amp with an American 2x12 Cabinet, and warp it with a Recitified Amp using a British 4x12 cabinet. After selecting Preset 40, the GNX1 will be ready to select the Amp Models (indicated by the yellow Status button LED).

  • Page 32: Adjust The Green Channel Parameters, Adjust The Red Channel Parameters, Tune The Cabinets

    ECTION UTORIAL Adjust the Green Channel Parameters The Tweed amp that we selected for our Green Channel assignment will initialize with factory default settings for the Gain, EQ, and Level Parameters.These settings may not necessarily suit your personal taste and require some fine tuning.To access these Green Channel Parameters, press the Status button once.

  • Page 33: Warp The Green And Red Channels Together, Assign Models To The Preset Channels

    When we have the Amps and Cabinets in our Green and Red Channels dialed in to suit our taste, we can Warp them together to create our new HyperModel™. Make sure your GNX1 is in yellow mode (indicated by the Status LED lighting yellow).

  • Page 34: Edit The Preset, Turn The Compressor Off

    ECTION UTORIAL Edit the Preset The next step to creating our example Preset is to enter the Preset Edit mode.To do this, press the Effect Select Down button once. At this point the Matrix LED in the Wah-Pickup row should light.The Display will briefly show EDIT and then cycle between showing the status of the Wah and Pickup simulator Effects.

  • Page 35: Adjust The Eq, Adjust The Noise Gate

    Effect Select Down button again and the LED on the Equalizer row will light. The GNX1 will default to the EQ adjustments for the Red Channel and the Display will briefly read EQ RED (EQ Red).

  • Page 36: Select And Adjust The Chorus, Turn The Delay Off, Select And Adjust The Reverb

    ECTION UTORIAL Select and Adjust the Chorus Next we wanted to thicken up the sound in our Preset by adding a subtle Chorus effect. Press the Effect Select Down button again and the LED in the Chorus/Mod row will light. If the Display indicates that this module is off (EFFOFF), press the Status button until the Display reads EFF ON (Effect On).Then rotate the Number 1 Knob until the Display shows CHORUS (Chorus) as the effect type.

  • Page 37: Store The Preset

    Store the Preset The last step that we need to do is to store our changes to a User Preset. If we changed Presets or turned the GNX1 off without storing these settings, it would forget what we had done and revert back to the original Preset. Press the Store button once.The first letter in the Display begins to flash which is asking us to rename the Preset.
