Did I miss part of the story? It looks that the "mystery" being revealed is someone degooped a pedal that is supposed to be a clone of the CJOD? How does anyone know that the degooped pedal is anything like the CJOD....
Just sayin'....

So a Youtube clip of a pedal that seemed to sound like a CJOD was the determining factor that the circuit is the same. Riiiiiiiiight.......

There were also a couple of CJOD owners here who said they sounded indentical when played side by side. When these things are added to the builder's claims that he copied a CJOD, there would seem to be a high likelihood that the story is right IMO. You may choose to believe otherwise, and that's fine. I was just trying to reply to your original question.... not have an argument that neither of us can win... Have a nice day.  BTW John. Do you have a CJOD ?

Part of this post was taken from the Tonepost forum on the CJOD/BMOD per a email quote that was posted from Kris the builder of the BMOD.
I've decided to build 50 clones of a discontinued highly sought after overdrive pedal that goes for a grand and over on ebay. My version uses all the same high quality parts and values utilized in the signal path. Some of the lower quality non-audio parts have been upgraded such as the radioshack solid core wire and perfboard. I will be using high quality dual-sided boards with platted-through holes and thick traces. The board layout is very similar to hold true to the original however I did make some slight changes to clean things up. The only thing you won't be getting is the swirly paint job, mainly because I think it's ugly. I use a high-quality powder coating process with a dark metalflake finish. The interesting thing to me is the Clay components were on a bread board, per the picture that Bob Burt posted of his overdrive that Clay built for him which is supposed to be based around the incarnation of the CJOD. The degooped BMOD on Freestomp is on a circuit board, so if a real picture of a degooped CJOD is ever shown it will be interesting to see how it compares to the BMOD with the circuit layout. From the people who own both the CJOD/BMOD it appears they are identicle sounding regardless of the bread board vs circuit board layout and updated components that Kris said he used to clean up the original design. Cheers Joe

History of the CJOD/BMOD Picture
I took this from that BLOG again. It's from the FSB.org forum though. Pretty much shows the similarities between the CJOD that "Kris" degooped and the BMOD he now makes - they are obviously identical...

How does Bob Burt's degooped pedal look so much cleaner than whammy's or was his ever gooped?

For those interested I drew up several schematics to outline the differences between a TS808, an L'DO, and a BMOD/CJOD (each links to it's schematic). Let me be clear on this - I drew these schematics from readily available information right here on TGP, other resouces on the internet, and from my own builds. They are not copied, duplicated, or re-posted protected artwork. These are my own diagrams. (please let me know if you see any errors - thanks!)
The L'DO schematic shows the component changes from a stock TS808 circuit surrounded by a red border. From the stock TS808 circuit 4 passive component values are changed (2 resistors, 1 capacitor, 1 potentiometer) and the pair of clipping diodes are swapped out for 3 diodes, 2 LED's, and a switch to toggle between them. The BMOD/CJOD schematic shows the component changes from a stock TS808 circuit surrounded by a red border. It also shows the component changes between the L'DO and the BMOD/CJOD surrounded by a blue border. From the stock TS808 circuit 4 passive component values are changed (2 resistors, 1 capacitor, 1 potentiometer - value changes are identical to the L'DO), the pair of clipping diodes are swapped for a pair of 5mm red LED's, and the JRC4558D dual op-amp IC is swapped for a Burr Brown OPA2134PA. From the L'DO circuit only the dual op-amp IC and clipping section differ. The circuit topology for all three circuits is identical (save the clipping section of the L'DO). Any TS808 or TS808 clone may be easily modified to L'DO or BMOD/CJOD specs. To modify a TS808 to include the clipping options of an L'DO you'd have to drill a hole in the enclosure to mount a switch and terminate the diodes and LED's to each side of the switch. The L'DO mods would cost about $10 dollars in parts. The BMOD/CJOD mods would run you about $5 in parts. You could get really particular about either mod and change all of the resistors to carbon composition type and the non-polarized capacitors to metalized polyester film type but the audible difference to most ears would be negligible and most likely not worth the effort. Layout / component and trace proximity can also affect the sound of the circuit but not in any significant way. Component tolerances and actual values throughout any of these circuits can also have some effect on the sound - anywhere from nearly imperceivable to noticeable depending on how far off the indicated value and how many values are off. Even still if you have a build or modified pedal that matches any one of these schematics that pedal is going to sound anywhere from 'very close' to 'exactly like' the pedal that schematic represents. I can't speak to anyone else's experience but I can relate my own. I bought CJOD #B19 directly from Clay. I used it as my primary overdrive sound for more than 2 years and most of that time using the same amp I own now. I am very familiar with the CJOD's tone and feel. Last year it's resale value reached a threshold that far outweighed its usefulness as an OD pedal for me and so I sold it. A couple of days ago the circuit details of the BMOD were posted on the net. Upon reading this information I opened up the L'DO clone I recently built for myself and made the two necessary changes to make it a part for part match to the BMOD. This resulted in a pedal that sounds and responds exactly the way my CJOD did and sounds just like the recordings I'd made with my CJOD. One could argue that I'm depending on faded memory to make this comparison and they'd be entitled to that opinion. I don't really need for anyone to believe my experience to validate it. I am only presenting it as additional information for those who may find it useful. Using my own experience, the technical information I have compiled and presented above, and the resources and details provided by others which I used for this effort I have come to the conclusion that the CJOD was/is a lightly modified TS808/L'DO as represented in this schematic. I can't personally say with absolute certainty that this is true. What I can tell you is that if that shiny black goop in the CJOD contains a circuit not resembling this schematic then Clay took a very long road to arrive at a circuit that sounds and feels just like an L'DO with 5mm red LED clippers and a Burr Brown OPA2134PA dual op-amp IC. Given Clay's other posted projects and expressed interests this scenario seems highly unlikely. In the end any person interested in this mess will have to draw their own conclusions. While the relevant information is scattered about the internet it's all within reach (most has been linked in this discussion I believe).
