I usually try to steer clear of topics like this one here because the ensuing discussions usually turn ugly fast. I hope this one doesn't. I bought #B19 CJOD directly from Clay and kept it on my pedal board for several years. It was a great sounding, fairly dynamic overdrive that I bonded with easily. There came a time, however, when its resale value way outweighed its usefulness for me and I sold mine. There are so many great sounding OD pedals available these days and I can make most any decent sounding dirt pedal work for me so I've never regretted selling the CJOD. With that said my curiosity regarding the circuit has never waned. It wasn't just the sound of the pedal that kept me curious (though this certainly was a contributing factor). It was that big glob of shiny black goop hiding, well, something. The sign reads 'WET PAINT - DO NOT TOUCH'. I'm the guy who touches the paint to see if it's still wet - cant help myself. The only attempt to degoop a CJOD that I am aware of ended in disaster and at a TGP members expense. Clay fixed it even though he was under no obligation to do so - very cool of him. This doesn't mean that it hasn't been done. I'm simply stating that I've no knowledge of anyone successfully doing so. Recently a CJOD clone has made its way to market - the BMOD made by Blackmarket FX (sp?). Though I personally had no interest in buying another overdrive pedal I found the subject and related discussions interesting. I hope I am not misrepresenting Blackmarket FX in stating that the BMOD is claimed to be a circuit clone of the CJOD. Several CJOD owners have recently done side-by-side comparisons and the posts I've read would seem to indicate that the CJOD owners found the BMOD to be an accurate sonic and tactile representation of the CJOD. Three possibilities here: 1) someone was able to successfully degoop a CJOD making it possible to build part-for-part clones; 2) someone with a great set of ears and experience building effects pedals was able to build an indistinguishable sonic match using only their ears as a guide; or 3) Clay provided the circuit details to someone. I don't think it matters how. I think it's cool enough that someone interested in trying this nearly unobtainable OD pedal has a viable alternative. While, as I said before, I'm not aware of any successful attempt to degoop a CJOD there has been a successful degooping of the BMOD. I didn't do it - I don't have one. I don't think I could bring myself to put $300 on the chopping block besides. Given my curiosity, though, and my growing interest in building dirt pedals I couldn't wait to have a look at this thing. I found the details most surprising. There have been rumors floating around that the CJOD was a Landgraff DO clone with LED clippers and no clipping switch. While the degooped pedal is not an actual CJOD it is being represented as a CJOD clone. So what was inside the black goop? The BMOD is a Landgraff DO clone with two minor changes - the clipping switch and associated diodes and LED's have been replaced by a pair of red LED's and the JRC4558D dual op-amp has been replaced with a Burr Brown OPA2134PA dual op-amp. Otherwise the circuit is a part-for-part clone of a Landgraff DO. I was skeptical so I opened up the L'DO clone that I built for myself, swapped the 3mm red LED's for a pair of 5mm red LED's, and swapped the JRC4558 IC for a BB OPA2134. To my surprise it sounds and responds exactly like the CJOD that I owned (assuming my memory serves right). It certainly sounds just like the recordings I made with the CJOD. My L'DO clone is now a CJOD clone when the clipping switch is in the Marshall (LED) mode. Several possibilities here: 1) Clay built and sold 50 or so very slightly modified Landgraff DO clones dressed in shiny black goop; or 2) In the process of modifying a production pedal Clay inadvertently arrived at a circuit that sounds just like a Landgraff DO with the aforementioned mods applied; or 3) Clay designed a completely unique circuit that sound just like a Landgraff DO with the aforementioned mods applied. At this point common sense points to scenario 1. The Landgraff DO is a TS808 with a few components swapped and a couple of clipping options built using high quality parts. Nothing wrong with that - it's a great sounding circuit and John enjoys a fantastic reputation for quality and customer service. On top of that John is confident enough in the quality of his product and service that he leaves the circuits in his pedals fully exposed - nothing to hide. After some prodding Clay reluctantly agreed to build 50 pedals and sell them first come, first serve to a small online community. While it seems clear to me at this point that this pedal was a L'DO clone with a couple of changes those changes did result in a a pedal with its own sound and feel. Like the many other modded TS circuits in the boutique pedal market these changes were Clays contribution and he chose to keep the circuit hidden. Blackmarket FX is attempting to make a once inaccessible pedal accessible in the BMOD. This pedal is reportedly a clone of the CJOD meaning that there's nothing new to protect, just someone else's secret. Unless Blackmarket FX is producing the BMOD with Clays blessing or IS Clay himself there's no reason to keep the CJOD circuit a secret. I'm not trying to cast a negative light on Blackmarket FX. I'm simply passing along information that will no doubt have made its way here within the week; information that I have been able to verify to my own satisfaction. Honestly folks - if you're interested in finding out what the CJOD is all about the Blackmarket FX BMOD will definitely do the trick. From what I could deduce from the photos build quality is nice and quality parts were used throughout. Building these things is much more expensive than parts cost - several hours go into each pedal when their being hand assembled and wired. Whether or not the price is fair is a subjective thing but Blackmarket FX's price for the BMOD is within the range of other highly regarded dirt pedals in the boutique market. Either by reputation or simply because of their rarity the CJOD fits into this category. I'm OK with the asking price though I would have preferred they left the goop out of the equation. For the DIY'ers the CJOD circuit is a little more accessible. Either way I thought most folks would be interested in knowing what a CJOD is. Thoughts? Discuss.
