From the post
This layout is the legendary Klon Centaur, but without the charge pump. The charge pump is present in the original to keep the 2nd opamp from clipping. But since there are diodes before signal even reaches that IC, it may not matter. Check out this thread on FSB for more info and schematic. Without the charge pump, the circuit was much easier to layout for a smaller footprint. Still a fairly large board, but should still fit in a 1590B.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.

- two of the three 1uF electrolytics (below the 390pF, and right of the 1nF): the board prints 1uF with a polarity mark, the wiring diagram reads as '.1uF', which could be 0.1uF or just the mark
- 422K under the upper TL072: printed clearly, unusual value
