Wah Pedal, Auto Wah
The Wah effect creates a unique tone by changing the frequency
response characteristics of a filter. Auto Wah creates an automatic
wah by cyclically changing the filter, or by changing the filter in
response to the volume of the input. Wah Pedal lets you use an
expression pedal or the like to obtain realtime control of the wah
effect.
Mode 'only for Auto Wah
Selection for the wah mode.
LPF (low pass filter):
This creates a wah effect over a wide frequency range.
BPF (band pass filter):
This creates a wah effect in a narrow frequency range.
Polarity *onty tor Auto Wah
Selection for the direction in which the filter will change in
response to the input.
Up: The frequency of the filter will rise.
Down: The frequency of the filter will fall.
Sensitivity 'onty for Auto Wah
This adjusts the sensitivity at which the filter will change in the
direction determined by the Polarity setting. Higher values will
result in a stronger response. With a setting of "0," the strength of
picking will have no effect.
* When using the effect as a wah pedal, set this parameter to "0."
Frequency
Adjusts the center frequency at which the wah effect will be
applied.
Peak
Adjusts the way in which the wah effect applies to the area around
the center frequency. Lower values will produce a wah effect over
a wide area around the center frequency. Higher values will
produce a wah effect in a narrow area around the center fre-
quency.
* When using the effect as a wah pedal, set this parameter to "50" for a
conventional wah sound.
Rate *only for Auto Wah
Adjusts the frequency of the auto wah.
Depth *onty for Auto Wah
