From the vendor

Dunlop's Eric Johnson signature Fuzz Face, voiced for his violin-like sustain. The post says it is the standard two-transistor silicon Fuzz Face circuit with different values, and shows them on a photo of the board; it points to the freestompboxes.org thread where Marc Ahlfs (Skreddy) and Jeorge Tripps (Way Huge) discuss it.

  • Image 2 is not a schematic but a photo of the circuit board with each part's value written beside it; the parts are numbered here in the photo's order and which Fuzz Face position each one takes is not shown.
  • The transistor markings are unreadable in the photo (two silicon TO-92 parts; the board is marked 'x2').
  • The Fuzz and Volume pot values are not shown.
