027: OD/Hi-Gain Wah

This versatile effect offers two different-sounding
distortion modes (Overdrive and Hi-Gain), a
modulatable wah-wah filter, a speaker simulation, and
3-band EQ. It's suitable for guitars, organs, and general
sonic mayhem.

Wah Switch
This turns the Wah effect on and off.
Source
Selects the modulation source that switches the Wah on
and off.
Mode
This parameter controls how the modulation source
switches the overdrive on and off.
When Mode = Toggle, the overdrive turns on or off
each time you press the pedal or move the joystick. Via
MIDI, overdrive turns on or off each time the
modulation amount exceeds 64.
When Mode = Moment (short for Momentary), the
overdrive is normally off, and turns on only when you
press the pedal or move the joystick. Via MIDI,
modulation values above 64 turn it on, and values
below 64 turn it off.
Wah Sweep
Sweep Range
This controls the width of the Wah's sweep, from the
minimum to maximum values of the modulation
Source selected below.
Negative values reverse the sweep's direction, from
high to low instead of low to high.
Source
This selects a modulation source to control the Wah.
DRIVE
Pre Low-cut
This attenuates low frequencies before the signal enters
the distortion. Use this to create a sharper tone.

Drive Mode
This switches between two different distortion timbres:
overdrive and hi-gain distortion.
Drive
The amount of distortion is determined by the
combination of the input level and the Drive setting.
Wet / Dry
Higher input levels, and/or higher Drive settings,
mean more distortion.
Raising the Drive setting will also increase the volume;
you can compensate for this by lowering the Output
Level parameter, below.
Wet / Dry
Direct Mix
Sets the amount of the dry sound mixed to the
distortion.
Speaker Simulation
Switches the speaker simulation on/off.
Output Level
This controls the output volume from the Drive section
into the 3-band EQ. You can use this to reduce the
volume to compensate for high Drive settings, or to
prevent clipping in the EQ.
Source
Selects the modulation source for the output level.
Amount
Sets the modulation amount for the output level.
EQ
Low Fc [Hz]
Sets the center frequency for Low EQ (shelving type).
Gain [dB]
Sets the gain of the Low EQ.
