AstroClone

From the vendor

Thought I’d redraw the classic Astrotone circuit and tinker around a bit. With some mods, it sort of reminds me of a light-weight version of the Colorsound Overdriver. The schematic in the File Pack below has the vintage parts values (to the best of my knowledge). I’m calling this the AstroClone since it’s an Astrotone Fuzz clone (duh).

Included in the AstroClone File Pack is artwork for etching (600 DPI), schematic and layout images, and Eagle CAD files.

And below is the BOM for my take on the circuit. I dropped the tone control because it’s useless. I also changed up things a bit to get a little more output and a little more grit.
