From the post
Gotten a couple requests for this one. Here's Bajaman's second take at his AFD circuit with a better frequency response than the first AFD. More info here on FSB. Should fit nicely in a 1590B.
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 Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.
