From the post
Got a little Eagle excursion for Fuzz Friday. Here's the Fnord from Black Arts Toneworks. It's pretty much the same as the Escobedo Digital Octaver Fuzz with an added diode lift switch (though that's jumpered in the originals). It's a pretty gnarly fuzz with a wide range of tones. For you perfboard builders you should be able to translate this onto perf pretty easily.
Here's the schematic for reference:

Check before you build · 5 values the reader of this layout was not sure of
- 100k, vertical resistor at the far left beside the IC: crosshair overlaps the middle digits, could be 180k or 150k
- 2.2n, vertical capacitor between that resistor and the IC: small and overprinted, could be 22n
- 10k, vertical resistor right of the 1M beside the 22u can: the first digits are overprinted
- CD4070: the IC label is overprinted by the centre mark; read as CD4070 (14-pin)
- 10n, capacitor at the top right of the IC: overprinted, could be 100n
