Used on the room mics for Icky Thump, as stated by recording and mixing engineer Joe Chiccarelli in this October 2007 Sound on Sound interview.
“The Trident at Blackbird Studio D was used for monitoring, and also some guitar microphones, plus most of the room microphones. Some room mics went through an API 512, and a few through a crazy old RCA OP6 tube preamp. Most of the other close mics went through various Neve 1073, Brent Averill API 312 and Chandler TG2 preamps. Jack loves the sound of ribbon microphones, so we used a lot of them, on guitar amps, vocals, and as room mics: Coles 4038, Royer 121, AEA R84. I would have six to 10 room mics up, and would chose a stereo pair from them."
