D&M distortion; someone knows it?? (incl. schematic)

OK; I got this unit to fix for a friend. Fixing was quite easy (loose battery wire) so I had some time to trace it.

Anyone know the pedal? He asked me if I could find some information about it....... I just never heard from it.

Then the sound; on the Si side of the colour switch, the unit is a normal distortion pedal that only sounds "good" with both knobs at 100% and reminds me a bit of the Distortion +. With the colour knob to the Ge side, the sound gets really muffled and only a very bassy "overdrive" can be heard, but the sound lacks the push and clarity of the other setting.

  That's a Dist-Screamer or Tubetion+
  The clipping probably comes from the Opamp [lm741 as seen in DIST+] and the Feedback Loop of the Opamp [as seen in TS and TS derivatives].
  I'd guess the Distortion is like a TS with a bit of DIST+ mixed in.
  Looks pretty good 'on paper'...how's it sound ?

These guys look like they were ahead of their time with the "color" switch.  Now almos every booteek distortion has some sort of footswitchable function.
