From the post
Unique little distortion box from Bjorn. The original uses 1A1200 diodes (which are pretty big), but other (and smaller) silicon diodes can be used. Should fit nicely in a 1590B.

Check before you build · 3 values the reader of this layout was not sure of
- 14.7K: four resistors (columns 8, 10 and 12 and one horizontal on row J), printed clearly, unusual value
- D1, D2: the legend reads '1A1200', printed clearly, an unusual diode type
- 1uF near the Volume pads: drawn as a grey rounded box (film/box capacitor), not a round can, so not marked electrolytic
