From the post
"A boutique pedal homage to the unique onboard overdrive circuit in vintage solid state Vox Conqueror amps that George Harrison used on the White Album and other Beatles recordings. The White Pedal has four knobs that control volume (overdrive), gain (fuzz), treble cut, and a bass cut knob that acts as a mid-boost, while a fifth knob (the Yoko knob) selects the midrange frequency to boost for a parked wah sound"
