Section Three - Effects and Parameters

About the Effects

The GNX1 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 GNX1 has the
Effects connected in the most logical, and best sounding order.The following diagram shows the signal path through the
processing contained in the GNX1.
Effect Definitions
Each Effect within the GNX1 is fully programmable to suit your personal tastes and application. Understanding how
these Effects will alter the sound, and how each Parameter will alter the Effect will help you achieve the sound you are
looking for.The following overview outlines how each Effect and Parameter in the GNX1 will alter the sound.

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 35 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) engages and disengages the Wah effect.
Wah Type - The Number 1 Knob selects the type of Wah.Values include: CRY (Cry Wah is a traditional sounding
Wah), BOTIQU (Boutique Wah is a wide sweeping Wah with a more modern sound) and FULRNG (Full
Range Wah sweeps the entire spectrum of audible frequencies).
Wah Minimum - The Number 2 Knob is used to select the minimum point the Wah (WAHMIN) will reach in the
toe up position of the Expression Pedal. Ranges from 0 to 99.
Wah Maximum - The Number 3 Knob is used to select the maximum point the Wah (WAHMAX) will reach in the
toe down position of the Expression Pedal. Ranges from 0 to 99.
Pickup Type/Off -The Number 4 Knob selects the type of Pick Up to be be simulated.Values include: PCKOFF
(Pickup Simulator Off), SC>HB (Gives a single coil pick up the warm tone of a humbucker), and
HB>SC (Gives a humbucker the unique sound of a single coil).
The Number 5 knob has no function when the Wah-Pickup is selected.

Compressor

A Compressor can be used to increase sustain, and tighten up guitars. 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.
Compression Parameters are as follows:
Comp On/Off - The Status button engages and disengages the Compressor.
Attack - The Number 1 Knob adjusts the length of time it takes for the Compressor to respond to a signal
exceeding the Threshold. Values include: fast, meDIUM, and slOw.
Ratio - The Number 2 Knob 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 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).
