From the post
I was asked if I could make a layout for the hendrix crybaby, so here she is. not a whole lot different from a regular crybaby. There are 2 additional caps, resistor change, and different value pot. You may be wondering what these changes do, and in short it moves the sweep range lower.
I have one, it was my first wah, which I got used for $30, and personally I like the lower sweep. I've also compared it with a few others I've built, Colorsound Fuzz Wah and aVox, and I feel there's a nice sweet spot with this one when playing single coils. I know there are those that aren't crazy about it, but hey not everyone has the same tastes.
