Used on vocals for Morning Phase, as stated in this May 4, 2014 Audio Technology interview with mix engineer Tom Elmhirst.

Elmhirst: “I love the Orban plug-in, and now also have a real Orban. But I didn’t use a lot of spring reverb on this album, because it had a different kind of sound. As I said earlier, the D-Verb Mark 1 was quite a big part of this record. Beck is a big fan of that plug-in, as am I. It’s very transparent. I probably EQ-ed it a bit on the way back in, and particularly on the vocals I used very long reverb settings, in some cases as long as 11 to 12 seconds. The other two plug-ins I used on the vocals are the Waves De-esser and a bit of brightening from the Waves API 550a.”
