Based on the Maestro Fuzz Phazzer FP-1
From the post
The layout is based on Brian Kepharts modernized version of this weird, fun and old device. HERE is a link to a very detalied description of this circuit, schematic, bias setup and explenations of the small but useful modifications.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
