Dead Air Face Disaster
Based on the Dead Air Face Disaster
From the post
Phew, February has been a wild month here on the blog so lets end it with a BANG. This one is based on Tim Escobedo's DIY classic, Ugly Face with quite a few added bells and whistles such as a optical LFO section, separate starve control for two of the chips and some tweaked values here and there. Schematic is avaiable HERE.

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.
