Nine Inch Nails – The Downward Spiral (Deluxe Edition)

There is a photo taken by Trent Reznor in his 1994 studio Le Pig during the recording of The Downward Spiral. To the left is the Amek Mozart console." - studio engineer Sean Beavan says: ""The studio was equipped with a 56-input Amek Mozart console with Rupert Neve modules...We loved the Amek Mozart console, because if you EQ'ed a Minimoog it would make it sound kind of cooler,”

"...We don't really have many sample-based workstation-type keyboards in the studio, except for the Kurzweil K2500."

The K2xxx series was also used a lot on the downward spiral. The guitar for "Hurt" is the acoustic guitar patch on the on the orchestral rom. The drums for "The Becoming" were also programed on a K2xxx series.

Clearly from the video, Trent is seen using a Parker Fly guitar, not to mention his admiration for the creator of the guitar, Adrian Belew, who Trent once cited 'is one of the best musicians alive'. Adrian Belew was also instrumental (no pun intended) to the development of 'The Downward Spiral'. https://www.musictech.net/guides/essential-guide/nine-inch-nails-the-downward-spiral/

Trent Reznor used a Gibson Les Paul Standard during the 1994 Downward Spiral era, as detailed in Collectionzz's documentation of his smashed guitar.
