Here's a unique overdrive design by Bajaman over on FSB. You can build it with either a buffered bypass or true bypass. If using true bypass, omit the 1k resistor below the lower TL062, and the 1uF cap and 100k resistor connected to the BP Out pad. To wire for buffered bypass, connect the In pad to the input jack, the FX Out pad to lug 1 of the footswitch, lug 2 to the output jack, and the BP Out pad to lug 3. More info and schematic over on the FSB thread. Thanks to 287m for sharing his layout.
Also, the next episode of the DIYLC Tutorial is up on YouTube. Almost have a completed layout!
