Mentioned by mixing engineer Michael Brauer as being used on "Violet Hill" in this Sound on Sound interview about the production of Viva la Vida & Death and All of His Friends.

Keyboards: Urei LA3A, Focusrite 115 HD, Neve Portico 5014

"The piano had my regular piano insert, which is two Urei LA3As going into my prototype Focusrite stereo 115 HD EQ. For some additional width I sent it to a Neve Portico 5014 Sound Field Editor. No reverb. I left the intro ambience as it was given to me. The keys had nothing on them either, not even EQ, jut flat, panned left and right. A lot of the tracks had hardly any EQ on them. Again, they did their homework and got the sounds that they wanted and didn't leave me to reinvent the song. What they wanted from me was to get their vision out there. That's my job."

Used for the guitar on Mosquitos, as stated by co-producer Joe Chiccarelli in this November 20, 2020 Mix Online interview.

Chiccarelli brought along some of his own equipment, as well: Focusrite and Neve preamps, UREI 1176 and LA2A compressors, a pair of Tannoy SGM10B monitors, and various microphones. (...) On guitars Ridgway and Chiccarelli used a Neumann U87 or Shure SM57 going into the producer’s Focusrite 115 preamps and 1176 or LA3A compression.
