Nobels DT1 Distortion

Not too much info around on this beloved cheapo pedal, but it seems to be of fairly good design. For the layout, i've omitted the input buffer to keep the size down. The output buffer has 2SK30-style pinout for couple of reasons. First, the original (schematic states K222E) is not that common. Second, it's just a buffer, so you should have exactly the same results with any NPN BJT in its place. Third, some of you might really want to try this with a BJT instead of JFET to preserve the stock they have. I thought about omitting the output buffer too, but the tonestack has vref voltage in it, so there has to be something to put that out before the output.

Straight-as-straight-can-be Distortion. A must-have for every Hardrock or Heavy Metal player.
