From the post

This layout is for the distortion side of the Box of Rock. The Boost side is just a SHO. I've laid this effect out for top mounted pots like in my other Zvex layouts and should fit vertically in a 1590B. Pots are 1.1 inches (28mm) apart.

Board dimensions: 3.2 x 1 in. or 81.3 x 25.4 mm

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.
