Zvex Woolly Mammoth Variations

[thekorean]

Hello,
I was looking at a woolly mammoth on craigslist that was a good price. For some reason though it has the knobs of a fuzz factory on it and the footswitch seems to be a little different than other woolly mammoths with the same paint job. However, there seems to be a bunch of different variations over the years. The seller said it was purchased in 2005 if that's any help. I was wondering if anyone has owned or seen one like it.

Thanks
