Insert Effect Parameter Functions

Wah

The wah effect creates a unique tone by changing the frequency response characteristics of a filter.

Touch wah creates an automatic wah by changing the filter in response to the volume of the input. Pedal wah lets you use an Expression pedal or the like to obtain real-time control of the wah effect.

* You can use this effect with the following algorithms when

When “PEDAL” is selected

The effect of the wah pedal can be obtained by operating the Expression pedal.

For a detailed explanation, refer to “When Using an Expression Pedal” (p. 187).
