Gary Automatic Pulse Width Modulation Fuzz and Dynamic Natural Overdrive. The EarthQuaker Gary is a unique pedal designed for the modern guitarist, offering a dynamic and destructive pulse width modulated fuzz paired with a natural-sounding overdrive. The fuzz side features an envelope-controlled variable pulse width that reacts to your playing dynamics, creating a saturated fuzz tone with a thick, heavy square wave characteristic. The 'Yes!' control adjusts sensitivity, allowing the user to explore how aggressive or subdued the fuzz can be. On the left side, the overdrive offers a clean boost that transitions smoothly into a rich distortion, based on the lineage of the now discontinued Gray Channel. This dual-function pedal captures a wide array of tonal possibilities, operating smoothly between lively cleans and biting fuzz, making it a versatile addition to any pedalboard.
