Back again with the Boss HF-2 as per the schematic located here:
http://www.freeinfosociety.com/electronics/schemview.php?id=133.
Similar to the Boss BF-2 except for a few components with altered values, some noise filtering on the power supply somewhere in there and an MN3204 instead of the MN3207. Layout has some common/popular substitutes but I have listed the original parts in case you have them/want to use them. Just check the transistor pinouts, you may have to twist the legs. Happy days.
