EarthQuaker Devices Gary Product Specifications

Fuzz Section (Right Brain)

Garys right brain consists of a dynamic and destructive fuzz that is both domineering and interactive. It features an envelope-controlled variable pulse width and turns the signal into a square wave. The Yes! control adjusts envelope sensitivity, affecting sustain and tone response. As sensitivity increases, the tone becomes nasal and biting until it disappears entirely, creating a unique pulsing effect.

Overdrive Section (Left Brain)

Garys left brain offers a simple and natural-sounding overdrive based on the green channel of the Gray Channel pedal. The Go control adjusts gain, from a clean boost to full-bodied distortion. Thats It serves as the master volume for the overdrive section.

• Thats It: Master volume for the overdrive.
