In the words of Boss:

Fuzz was the first type of distortion pedal, and the retro sound of vintage units from the 1960s remains coveted by guitarists to this day. Realized through deep analysis of many legendary pedals and detailed Waza craftsmanship, the all-analog FZ-1W delivers the inspiring tone, feel, and vibe of classic fuzz in a reliable modern design. And like all Waza Craft pedals, the FZ-1W features premium components for top-quality performance and extended range for maximum tonal versatility.
