The Bigfoot Yak Face is a very high quality 3-band EQ with controls for treble, middle, and bass frequencies. Inspired by the classic Super Reverb amplifier, the Yak Face has 3 powerful controls which offer a broad, smooth sweep through a huge range of tones. Bass frequencies can soar from tight to thunderous, mids from scooped to punchy, and treble from warm to sparkling with ease. The sonic ability of this pedal will truly put all your existing tone controls to shame.
