From the vendor
This is a fabricated version of the old ONE-KNOBBER project from the blog. The only difference being an added current limiting resistor (usually 4.7k). You can build this board to 6 different versions of the classic Colorsound One Knob fuzz, including the D*A*M Meathead, Blackarts Toneworks Ritual, and several more. Or use some sockets and experiment. An easy fit in a 1590A and a really fun and versatile project.
