From the post
Here's an interesting and fairly simple noise gate circuit sent to me by Stanik Nupel from a Polish electronics book. Schematic and Stanik's original layout can be found here. The switch isn't in his original layout, so it may not be all that necessary. It'll be a tight squeeze in a 1590B, but should fit especially if you're using low profile jacks. Otherwise it'll fit nicely in a 125B with top mounted jacks.
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.
