Around 2007, prior the recording of Death Magnetic James started experimenting with Krank Krankenstein and Revolution 1 amps, which he ended up using on the album.

In this article from Guitar World, they write that Darrell collaborated in designing this amp, but was killed before the official release of it. "Dime started using a Krank Revolution stack onstage with Damageplan, but he also started collaborating with Krank amp designer Tony Dow on a new model that became known as the Krankenstein. Dime called it a “super hot-rod hell-raiser version” of the Revolution. 'I got rid of everything in my rack,' Dime said. 'Now I go straight into the Krank and let it blaze. The less shit you run through, the more pure your tone is. I always thought that I had to have my six-band EQ and my PQ4 and jack everything up to high hell. Now I plug in and let it rip.'"

Patrick used the Krankenstein during touring for "From Under The Cork Tree", he then switched back to Dual Rectifiers.

He used KRANK Krankenstein Head on the NEVERMORE - The Year Of The Voyager DVD

This gear diagram of Michael's stage setup includes two Krank Krankenstein heads.

Noodles used a Krank Krankenstein amp to record "Rise and Fall, Rage and Grace" album.

"And then the Dimebag Darrell Krank amp which actually sounded really good. [Laughs] I wouldn't think that a Dimebag Darrell amp would work for us at all but it really sounds really good. It's a lot more varied; not that there's anything against Dimebag, it's just different styles, you know what I'm saying? It's actually a really cool and great amp." - Noodles

Three Krank Krankenstein heads can be seen in this detailed gear diagram of Christian Olde Wolbers' Fear Factory stage setup.

In this YouTube video of Bring Me the Horizon playing live in Boise, Idaho at Warped Tour 2008, you can see Curtis Ward playing through a Krank Revolution 1 preamp, along with Lee Malia playing a Krankenstein. If you go onto the Internet Archives and look at the Bring Me the Horizon website you can also see they were proudly sponsored by Krank amps. Multiple other videos from the 2008 Warped Tour also show them playing through Krank heads.

Lander states that both she and McLeod use the same amps/cabs:

Lander: I like my guitars to be basic. I’m playing a custom Hamer Victor, but I didn’t want much in the way of modifications. I asked for EMG 81 pickups, because they are good for metal, and I was good to go. We both use the Krank 100-watt Krankenstein Dimebag Darrell Model through Krank 4x12 cabinets. The amp was designed with Dime in mind, so it has the appropriate edge and balls. I’ve always loved straight amp distortion. Simple works best for me.
