I'm interested in building a pedal with the Sabbath Distortion PCB but it seems that the MPF4393 semiconductor is no longer in production. Is there an alternative for this or does anyone know of a source for them that Google doesn't? Or am I out of luck?
SMD version is getting harder to find too, but Digikey has them. Solder it onto an adapter board and you're good to go. If you haven't done SMD soldering before it's not that hard.
