From the post
Phew, loys of work lately so not much time for the blog and building lataely. A few people have sent me some new traces and new layouts. These will be uploaded today. First out is Little Acid Fuzz by Frost Giant Electronics.
Another Frost Giant PCB traced by Sergio. Based on the op amp version of the Little Big Muff from the late 70s. The internal Tone trimmer can easily be moved to the outside for a 2-knobber.
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.
