Fuzz-Wah overview in MainStage
The Fuzz-Wah plug-in emulates classic wah effects, combined with compression and fuzz distortion effects. The name wah wah comes from the sound it produces. It has been a popular effect—usually a pedal effect—with electric guitarists since the days of Jimi Hendrix. The pedal controls the cutoff frequency of a bandpass, a lowpass, or less commonly a highpass filter.
To add Fuzz-Wah to your concert, choose Filter > Fuzz-Wah in a channel strip Audio Effect plug-in menu. See Add and remove plug-ins in MainStage.

Fuzz-Wah effects work in series—where the output of one effect is fed into the next in an effects chain. The routing order lets you choose whether a distorted signal should be wah-filtered (for funkier sounds) or the wah-filtered sound should be distorted (for screaming sounds), for example.
Horizontally drag the name of the effect to determine the order of the effects chain.
