From the post
Here's one of the most classic effects of all time, the Cry Baby wah-wah from Dunlop. The big red thing in the layout is the Fasel inductor, and there's room on the board for a pull down resistor at the input if you need it, I just didn't include it in the drawing. What else is there to say? Just build it!
