Buffered Bypass

Prepare for a bit of rambling: I was looking through the de-goup thread for the Cornish G2 over on Freestompboxes.org and was intrigued by the buffered bypass switching that's used on that pedal. (Before people bombard me with requests for the G2, don't worry it's coming.) Original G2s have individual PCBs for the footswitch, the bypass buffer, and the effect. Surely the first 2 can be combined, right? So I drew up the Cornish buffer with a board mounted footswitch (which I will share when I post the G2 layout), but it was too big to fit in a typical 1590B with the footswitch centered in the enclosure. Then I got to thinking about replacing the buffer circuit with one that took up less space. So I drew it up with the input buffer from the Klon and it will fit very nicely in a 1590B. This uses a board-mounted DPDT footswitch (I bought a bunch from Tayda a while back) and the on/off indicator LED can be mounted to the board as well.

I verified this over the weekend and here's a few pics of my build.
