Would kill for a layout for this, even though I have no idea what it sounds like. There's hardly any info about these other than an old freestompboxes post, and a few random schematics floating around. This seems to be the most complete one. No experience with Bi-Polar power supplies either, so not sure how easy it would be to convert to regular 9v adaptor power. http://www.freestompboxes.org/viewtopic.php?f=1&t=16394
