The Anubis Silicon Fuzz is a fuzz pedal that is based on the Basic Audio Scarab Deluxe circuit. The Scarab Deluxe itself is an adaptation of the classic Tone Bender Mk. II circuit, but with the use of silicon transistors and a Big Muff-style tone control.

The Anubis Silicon Fuzz was first released in 2010 as the successor to the original Scarab, which was based on the Hot Silicon circuit. The Hot Silicon is a well-known circuit in the DIY community that also adapts the Tone Bender Mk. II for silicon transistors.

The Scarab Deluxe added some additional features to the original Scarab circuit, including an input capacitor blend and an external bias control for the third transistor. These additions allowed for more tonal flexibility and control over the fuzz sound.

The original Scarab was discontinued after the release of the Scarab Deluxe, as the Deluxe version offered improved features and performance.

The Hot Silicon circuit is also available from Aion FX as the Zircon Silicon Fuzz. The Zircon and Anubis projects are very similar to each other, but they have enough differences that they cannot be built on the same PCB (printed circuit board).

Overall, the Anubis Silicon Fuzz is a fuzz pedal that builds upon the legacy of the Tone Bender Mk. II circuit, incorporating silicon transistors and additional features for enhanced tonal control.
