In a MusicRadar article authored by Amit Sharma titled "In pictures: Slipknot’s Mick Thomson shares his favourite guitars and gear from an extensive collection," Mick Thomson is shown with a variety of his guitar pedals, including the Electro-Harmonix Sovtek "Green Russian" Big Muff Pi V7C. Although Thomson does not discuss this specific pedal in the article, its presence in his collection is clearly documented through the accompanying images.

Lot 41 in the 2020 Cafe OTO COVID-19 Fundraiser Auction. This March 19, 2020 video was recorded to promote the auction.

Hi, my name is Thurston Moore and I am offering this Sovtek Big Muff pedal that was made in probably the 1990s... 1980s, 1990s, to Cafe OTO for their auction for getting some new equipment into the space. This pedal I used for about ten years in Sonic Youth and I think 2004 to 2014 is when I purchased it, uh, somewhere. Went through a few of these through the years and they would just like, I would just... they would just die. I would just kill them on tour. This one went through the wars, as you can see it's really, like, went through the wars. It might even still work. I haven't used it in quite some time. It is an objet d'art as they say [laughs] somewhere. I've inscribed it. It's a conversation piece and it's yours if you would like to bid on it.

In this pic, the pedal next to the DMM looks a lot like a black Sovtek Muff

Mentioned in this October 13, 2017 Red Bull Music Academy article.

“It doesn’t get too high-end and cut through and make an unpleasant sound to the ears,” says Troy Sanders, who plays bass in Atlanta metal pioneers Mastodon. “It’s just the thickest, purest, roundest, warmest, most glorious bass distortion sound that I’ve ever had.” The Big Muff also holds a curious position in guitar history: It’s a gold standard as far as distortion pedals go, but it also serves as a barrier-breaker to get into other kinds of effects, too. “That is the gateway sonic drug that’s now got me addicted to pedals,” Sanders laughs. “I don’t blame myself, I blame the Big Muff. I blame the green, Russian-made Big Muff for all my problems and successes.”
