Wah Wah And Envelope Filter Plug-In

Kuassa WF3607 Wah Filter for Mac and Windows features 6 filter modes   27-Feb-18

Kuassa has released the WF3607 Wah / Filter FX Engine. They say that, designed to mimic the “wa wa” sound from a Wah pedal, it features 6 modes of filtering effect taken from the familiar crybaby sound to synth-like filters. Here’s the story in their own words...

In the 1920s guitar players were fascinated by the “wa wa wa” sound made by trumpet players by opening and closing their mutes. Its filtering effect alters the resonance of the instrument and it feels to increase the expressiveness of playing.

More than 40 years later, an accidental invention resulted in a device that forever changes the sound of guitar. This pedal eventually known as the Cry Baby*. Next, in the 1970s, an aborted synthesizer project resulted in an similar “wah wah” effect, which later known as Mu-Tron* III envelope filter. These two devices revolutionized almost every genre of music as we know it today.
