The Sonuus Wahoo is a dual analog filter stompbox 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 analog signal path is digitally controlled and offers 100 factory presets and 100 user presets. Its Drive knob lets the user control the overdrive of the filters. Powered by adapter, AA batteries or USB, the pedal can also be used with its Desktop Editor software for preset editing and manipulation, and its firmware is upgradeable. See more at sonuus.com.
