From the post
The Talons is a great sounding overdrive pedal and is EQD's take on the Marshall Guv'nor. FSB member Zedsnotdead traced it and requested a layout with board-mounted 9mm pots to fit in a 1590B. As per usual, the pots should be mounted on the solder-side of the board. Watch out for the EQ pots as they are oriented 180º differently from the top row of pots. The in and out pads ended up in a bit of a weird spot, but shouldn't be an issue. (You'll just have to use a little more wire to get to the footswitch.)
