Wah-Wah

The WAH-WAH FX unit was modeled after classic wah-wah pedals of the 1970s. It’s a fun and versatile effect that doesn’t sound like any of the other Trilian Filters. This FX unit works both as a sweeping wah-wah and also as an “auto-wah” envelope filter effect by using the controls on Page 2.
