I can only tell you that they both have the charge pump chip, which doubles the voltage rails to 18v for greater headroom, dual TL072 op-amps, and dual gang gain pot, which keeps the same percentage level of clean mixed in with the dirt as you turn up the gain, which are all aspects of the original Klon design. I can't tell you whether the whole schematic layout, parts used, or other details of these Klones stay true to the original. But, I care much more about whether I like the way they sound, rather than how accurate they are. I do know that the Crème Brulee, Bad Horse, and Clone Central are so similar sounding that if I were blindfolded, and someone else switched between the three while I played, I don't think I would be able to tell which is which. From what I can recall of the one you're getting, I think it's a bit brighter than the others, so with the gain and tone cranked up, it maybe sounds a bit more trebly. Otherwise, I probably couldn't tell it from the other three either.
