Rockman Distortion Generator

[wavley]

So, I made a joke recently that I sold my Rockman Distortion Generator to make room in my car when I moved to florida 18 years ago and I should have kept it and sold the stupid bird my parents gave me and the dude that bought it from me volunteered to give it back.

So now I have my old DG on it's way back to me.

Has anybody seen the schematic on this?  I'm not sure which revision it is until I get it, but the guy at http://www.rockman.fr/Reviews/DG.htm says

The limits of the DG come from what was cleared in order to obtain a cheaper device: no Smart Gate, and no loop for an external pre-distortion EQ. I have corrected that on my September 1991 DG, and added the two features: my DG is now perfect!

I don't really need the loop, but the smart gate would be awesome.  I'm guessing that it's a pretty simple mod with a fairly low parts count, but I would like to compare the schematics of the Sustainor and the Distortion Generator to confirm this.
