<blockquote>The studio was equipped with a 56-input Amek Mozart console with Rupert Neve modules, two Studer A800 Mk3 multitrack machines, Mac-based Pro Tools and a host of outboard gear, in addition to Akai S1100 and Kurzweil K2000 samplers; Prophet VS, Digidesign Turbosynth, ARP Odyssey, Oberheim Expander, Oberheim OBMx, Roland MKS80 and Minimoog synthesizers; Doepfer and Oberheim sequencers; a Mellotron MKIV polyphonic tape replay keyboard; a Roland R70 drum machine; and assorted Jackson and Gibson guitars.[http://www.soundonsound.com/sos/sep12/articles/classic-tracks-0912.htm]</blockquote>
The Mellotron MKIV used on the album (as well as on ''Broken'') once belonged to John Lennon. Engineer [[Sean Beavan]] remarked to ''Sound On Sound'' in the above referenced article that it still had The Beatles' tape loops in it. Contrary to popular belief, it was is not used to record The Beatles' "Strawberry Fields Forever", nor is it owned by Reznor. It was on loan to him from [[Interscope Records]] co-founders Ted Field and Jimmy Iovine.[https://www.rollingstone.com/music/music-news/nine-inch-nails-the-pleasure-of-pain-2-172188/]
