Christ! I had a Korg "Hard Dist" when I was about 18, perhaps the most repellant filth pedal I have ever tried before or since, with an utterly unusuable tone control that went from super-muffled to "aaaaghh, my cochlear has ripped open" in less than a degree of rotation. Cheap looking boxes, but actually really solidly built. Not sure what happened to it, in no hurry to build another...

A long time ago I even made the Overdrive and Hard Distortion clones.
Overdrive was much better but as far I remember the sound of the Hard Distortion could have been improved with a couple of mods.
Schematic shows that it is quite similar to Boss DS-1.

I merged this with an older thread on the subject, which immediately revealed these were published earlier, all links above are dead.
I am in the process of splitting out the pdf into pdf's per effect, to publish them in the correct thread.
So we don't we lose them again...
