A quite interesting one. It is basically an old Tim Escobedo circuit (Punch in the Face silicon/FET fuzz face variant) sandwished between two op amp gainstages. The input cap is only at 220pF, try 4,7nF-10nF to fatten things up a bit. A trimpot is added for easy biasing for the J FET. Stock fixed value is 5,6k.
Schematic is avaiable HERE.
