From the post
Here's one of the earliest Catalinbread designs, the Supercharged Overdrive. It's a pretty unique circuit with the Contour control adding in more distortion and saturation from the CD4007 stage. Laid out for board mounted pots and will fit quite nicely in a 1590B. Schematic here for reference.
