Blue Cat's Miaow Wah is an augmented virtual Wah pedal plug-in, capable of simulating a wide range of Wah pedals, auto filters, modulation effects and more.









The plug-in includes a wide variety of predefined Wah models from all eras. They can all be controlled manually with an expression pedal, or can be triggered automatically in the "auto" (envelope follower) or LFO modes to your taste.
It is easy to create your own Wah pedal from factory presets with the built-in Tone Maps browser or the Wah editor.
With the ability to define custom filters with multiple control options, Miaow Wah extends the concept of a Wah pedal to flangy tones, univibes, phasing effects, filtered tremolos and more.
This plug-in is also available as a built-in effect inside Blue Cat's Axiom, the multi effects processor for guitar and bass.
