From the vendor

The Basic Audio Scarab Deluxe Fuzz builds on the best bits of the original like the germanium-voiced character and three-knob layout for level, tone, and fuzz and adds some extra goodies like a Bias knob for accessing additional circuitry and a Fat control for contouring the low-end depending on your pickups. Easily capable of dialing in a modern, aggressive buzz when need be, The Scarab Deluxe's ability to serve Tonebender-style sounds makes it a potent duo in one box.
