From the post
Got a request for an active DI, which coincided with a project I'm working on, so it seemed like a good idea. This one's designed by Samuel Groner and modified by Jack Orman. The schematic came from his blog and can be found here, along with some other info about the circuit.

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.
