Effect Definitions
Each Effect within the GNX4 is fully programmable. Understanding how these effects modify the sound, and
how each parameter alters the effect will help you achieve the sound you are looking for. The following
overview outlines how each effect and parameter in the GNX4 works.
Preset Levels
The GNX4 presets each have an independent level control for quick balancing of the levels between presets.
Preset Level is accessed by selecting the Wah – Pickup row of the Matrix using the Effect Select buttons
and then adjusting Knob 5. The Preset Level adjusts the overall output gain of the active Preset and the
range is from
0
to
. Preset Level changes need to be saved and stored to a user preset location just as any
other effect changes. See page 58 for more information on Storing a Preset.
Wah-Pickup
A Wah is an effect controlled by the Expression Pedal. A Wah applies a boost in gain to a narrow band
of frequencies. As the Expression Pedal is rocked back and forth, the center frequency receiving the
boost is swept up and down making the guitar sound as if it is saying "Wah". The Wah is engaged and
disengaged by applying pressure to the V-Switch located under the toe of the Expression Pedal. See page
104 for more information regarding the V-Switch.
The Pickup Simulator applies the warmth and thickness of a double coil humbucker pickup to a single coil
guitar, or the unique, crisp sound of a single coil pickup to a guitar with a humbucker. This allows you to
have the best of both worlds without ever changing guitars.
Wah On/Off - The Status button (or the V-Switch) turns the Wah (
Wah Type - Knob 1 selects the type of Wah.Values include: Cry Wah (
Wah, Boutique Wah (
Full Range Wah (
Wah Pedal - Knob 2 controls the pedal (
wah is active. The wah sweep range is from
linked to this parameter when the V-Switch is engaged. To adjust the minimum and
maximum range, see the Expression Pedal section on page 45.
Pickup Type/Off - Knob 3 selects the type of Pick Up to be be simulated. Values include: Pickup
Simulator Off (
up the warm tone of a humbucker, and Humbucker>Single Coil (
humbucker the unique sound of a single coil.
Knob 4 has no function when the Wah-Pickup is selected.
Preset Level - Knob 5 adjusts the overall preset level. Ranges from
Compressor
A compressor is used to increase sustain, and even out the volume dynamics in guitar signal. A
compressor sets boundaries for a signal's strength. When a signal exceeds the set boundary, it is forced
back into the set boundary. As the signal fades to a point where it no longer exceeds the boundary, the
compressor expands the signal strength and increases sustain. The compression parameters are as
follows:
Comp On/Off - The Status button turns the Compressor (
Attack - Knob 1 adjusts the length of time it takes for the Compressor to respond to a signal
exceeding the Threshold. Values include:
Ratio - Knob 2 adjusts the input to output ratio once the Threshold has been exceeded. 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
