How to select presets using your foot on the Sonuus Wahoo.
The Wahoo™ is a dual analogue filter stomp box where each filter can be configured as low-pass or band-pass and operate independently in wah pedal, envelope, LFO, and pitch-tracking modes. The warm-sounding fully analogue signal path is digitally controlled for precision, configurability and adaptability. Whether you want to recreate the character of vintage wah/filter pedals or break new sonic barriers, the Wahoo can do it for you.
