I've seen the schematic and tested the first Mosferatu AND Zendrive pedals. I also own the first Mosferatu M2 (2 Mos' in 1) and the first ZD/Mos 2 in 1 pedal. The Zen Drive IS NOT ts based.
Neither are the Barber Burn Unit, the Barber BU EQ (both have dumble settings), Menatone Howie, Ethos or the Jetter dumble pedal - all pedals that cop the dumble tone/vibe.
I think the rationale that most pedals are ts based is flawed thinking. Some people include the Foxrox ZIM as a ts based pedal. Really? With the Tar + (MXR Dist +/Rat), Big Muff, Octavia and/or Fuzz Face cards it is ts based? Those four pedals aren't on anyone's ts based list, so how could the ZIM with those cards be on such a list? As Dave Fox states: "The Fat Fuzz ZIM card consists of a medium gain Silicon NPN FuzzFace circuit". http://www.foxroxelectronics.com
Looking at the schematic again, it's very simple and in the general "TS style," but I think the tone control is different enough to say, it may be related, but it's not strictly in the TS family. In my opinion. Others may disagree.
Again, not that it matters...
You might want the check thread you started and "look at the schematic" again, there you claim the Zen Drive is "OD-1 based"/cloned/carries the gene, not "ts-9 based"/cloned/carries the gene.
Green = carries the TS gene
Blue = carries the OD-1 gene
