From the post
Another circuit by Mesa Boogie.
This one uses an Inductor, a dual LED and a different Bypass Switch wiring.
There's already an unverified layout (multiple boards) by Savvas in the Contributions section of the forum but I wanted to add one on a single board.
You can find the original thread and schematic here.
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 Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
