Selects the compression ratio that is applied when the effect
begins to operate.
WAH
This is a wah that produces distinctive tonal changes by
varying the frequency response of a filter. Pedal Wah lets
you use an expression pedal to control the wah effect. Auto
Wah produces a wah effect automatically, by varying the
filter frequency according to the input volume.
ON/OFF
Turns the WAH on/off.
* You can turn the VALUE dial to select PRESET.
TYPE
Select either “PEDAL WAH” or “AUTO WAH.”
● If the type is set to “PEDAL WAH”
FREQ (Frequency) 0–100
Adjusts the center frequency of the wah effect.
LEVEL 0–100
Adjusts the volume.
SET PDL (Setting pedal)
Assigns the wah function to the built-in EXP pedal.

POLARITY
Selects how the filter will move in response to the input.
SENS (Sensitivity) 0–100
Adjusts the sensitivity with which the filter will move
according to the “POLARITY” setting. Higher settings of this
parameter will produce a stronger response. With a setting of
“0,” your picking will not produce a wah effect.
FREQ (Frequency) 0–100
Adjusts the center frequency of the wah effect.
PEAK 0–100
Adjusts the amount of the wah effect that will occur in the
area of the center frequency. Lowering this setting will
produce a wah effect in a broader range around the center
frequency. Increasing this setting will produce a wah effect in
a narrower range around the center frequency.
* A setting of “50” will produce a typical wah sound.
RATE 0–100, BPM –BPM
Adjusts the modulation frequency of the auto wah.
* This effect assumes that you will press the foot switch to
trigger the effect only when you want to produce vibrato.It
would be useful when you assign it to the CTL pedal, and use
it while you perform (p. 23).

Adjusts the volume.
PEDAL WAH The effect will operate as a pedal wah.

Produces a wah effect over a broad fre-
quency range.
BPF

Produces a wah effect over a narrow
frequency range.
DOWN The filter will move toward a lower frequency.
UP The filter will move toward a higher frequency.
