Detail 01
Yes!
Sets envelope sensitivity for the fuzz and changes its duty cycle.

Independent shopping perspective
Gary combines pulse-width modulation fuzz with a dynamic op-amp overdrive in one pedal. On the fuzz side, the Yes! control changes envelope sensitivity and duty cycle; higher settings narrow the fuzz toward a more biting response, and the effect can disappear at the most extreme settings. Go moves the overdrive from clean boost to saturated distortion, while That's It sets its master level. Flexi-Switch operation lets either circuit be used latching or momentarily, and an expression pedal can shape the fuzz manually in real time.
