Mad AutoWah Tones on Tap Bring expressive, touch-sensitive funk tones to your pedalboard with the Mad Professor Snow White AutoWah (GB). Designed for both guitar and bass, this premium analog envelope filter delivers lightning-fast tracking, smooth vocal-style sweeps, and incredibly dynamic response that reacts naturally to your playing. Whether you’re chasing vintage funk rhythms, fusion leads, synth-like textures, or modern groove tones, the Snow White AutoWah offers studio-quality responsiveness in a compact pedalboard-friendly format. Originally inspired by Björn Juhl’s legendary custom rack wah circuits, the Snow White AutoWah has become one of the most respected envelope filters available thanks to its musical feel, wide tonal range, and precise control layout. The updated GB version combines the original guitar and bass voicings into one versatile pedal, making it a standout choice for multi-instrumentalists and tone enthusiasts alike. Fast, Musical Tracking With Incredible Sensitivity Unlike many auto wah pedals that can feel uneven or sluggish, the Snow White AutoWah tracks your picking dynamics with exceptional speed and accuracy. Light picking produces subtle filter movement, while aggressive attack opens up expressive, vocal-like wah sweeps that cut through any mix. The highly responsive Sensitivity control allows players to dial in the pedal’s reaction to different pickup outputs, playing styles, and instruments with ease. Full Control Over Your Envelope Filter Tone The Snow White AutoWah features an intuitive four-knob layout that gives players deep tonal shaping without becoming overly complicated. Controls Include: Sensitivity – Adjusts how easily the filter responds to your playing dynamics Bias – Sets the filter’s resting frequency and overall tonal character Resonance – Controls the sharpness and intensity of the wah effect Decay – Determines how quickly the filter returns to its resting position The unique Decay control is one of the pedal’s standout features, allowing everything from ultra-fast percussive funk quacks to slower, smoother vintage-style sweeps. Optimized for Guitar and Bass A dedicated Guitar/Bass switch instantly tailors the response and voicing for either instrument, making the Snow White AutoWah equally impressive for funky bass lines, articulate chord work, or expressive lead playing. Its wide frequency response and natural feel also make it popular with synth players and experimental musicians looking for responsive analog filter textures.
