Pdl Position (Pedal Position)

This adjusts the position of the wah pedal.

* This parameter is actually controlled with the expression pedal.

Level

Adjusts the volume.

■TW: Touch Wah

The filter behaves differently, depending on the volume level of the instrument being input. This provides a unique effect whereby the filter changes according to how you play.

Parameter	Value
Mode	LPF, BPF, HPF
Polarity	Up, Down
Sens	0–100
Frequency	0–100
Depth	0–100
Peak	0–100
Level	0–100

Mode

Selects the wah mode.

LPF (Low Pass Filter):

This creates a wah effect over a wide frequency range, including the low end.

BPF (Band Pass Filter):

This creates a wah effect in a narrow range of midrange frequencies.

HPF (High Pass Filter):

This creates a wah effect over a wide range of frequencies in the upper range.

Polarity

This selects the direction in which the filter changes in response to the input.

Up:

The filter rises from lower to higher frequencies in response to the input level.

Down:

The filter falls from higher to lower frequencies in response to the input level.

Sens

This adjusts the sensitivity at which the filter changes according to the polarity setting. Higher values result in a stronger response, such that the filter responds with great sensitivity even when the strings are played lightly.

Freq (Frequency)

This adjusts the reference frequency for the Wah effect.

Peak

This adds a particular character to the sound. Higher values produce a stronger tone which emphasizes the wah effect more.

Depth

This adjusts the depth of the effect.

Level

Adjusts the volume.

■AW: Auto Wah

This allows you to have the filter change cyclically or in response to the instrument’s volume, as with Touch Wah.
