Project overview

The Anubis Silicon Fuzz is an adaptation of the Basic Audio Scarab Deluxe, first released in 2010 as the successor to the original Scarab, which was in turn based on the Hot Silicon, a classic circuit in the DIY community that adapts the Tone Bender Mk. II for silicon transistors.

The Scarab Deluxe added an input capacitor blend as well as an external bias control for the third transistor. The original Scarab was discontinued after the Deluxe was released.

The Hot Silicon is also available from Aion FX as the Zircon Silicon Fuzz. The Zircon and Anubis projects are very similar to each other, but just different enough that they couldn’t be built on the same PCB.
