The wah effects are a versatile collection of different effects that can all be controlled by an expression pedal set up as Wah Pedal. Alternatively, you can switch to “Pedal Mode” option “Touch”, and control the effect using your picking strength.
Alongside the classic wah pedal, this effect type includes other wah effects such as low and high pass filters, talk box-type effects, special phaser and flanger variants and a ring modulator.
