From the post

The TS808 layout I post a while back has always bugged me. It's a real tight squeeze in a 1590B and I wanted a Tube Screamer layout with onboard pots. Well, I finally drew one up and I like this one. It's laid out for the TS9, but all it takes is 2 resistor swaps to go to TS808 specs (see the layout for info there). For board mounted pots, as per usual, right angle PCB pots can be mounted from the solder side of the board.
