I just sold a V2 last week. It's the only OCD I've tried, but the other guitarist in my band uses one for a boost, I'll check which one it is next time I'm over there because I know he definitely won't know. When my uncle and I A/B'd it with the OCD in the FM9 we got them sounding identical and we did the "there's a tiny, tiny difference somewhere, I can't pinpoint it, it's not EQ, it's not dirt and it feels the same, but it's somehow different" thing that I used to scoff at but know what people mean now.
It's such a meaningless difference that if you swapped between both of them for a entire day listening for the difference then walked out of the room and had someone cover everything up for you to come back and guess which one you were playing through, you'd have zero clue.
