In a February 2016 interview with MusicRadar, Oneohtrix Point Never's studio photos reveal the Kush UBK Fatso prominently placed near the top of his rack, highlighting its role in his production setup.
In a feature by XLR8R, Nosaj Thing is shown using the Kush UBK Fatso in his studio setup.
"For me, the essential gear is anything that can really put the hurt on a signal, like my UBK Fatso and lots of guitar pedals, especially the Electro-Harmonix stuff. Their SuperEgo, Freeze, POG2 and Pitch Fork are recent favorites, and I still get a lot of use out of my Zvex pedals, MXR/Dunlop Hendrix fuzz, and of course the green Line6 delays, both pedal and rack."
