Auto-wah

Plugin screenshot

The auto-wah is a combination of an envelope follower and a resonant low pass filter. For increasing sound levels, both the frequency and the bandwidth of the filter will increase. The intensity is controlled by 'Drive'. For a normal wah, use an expression pedal to control 'Frequency' and set 'Drive' to zero. Features: Modeled by FOMP
