When it came to actually laying down the sounds in the studio, did you change up your gear at all to be era-appropriate?
It's mostly the same gear. Although we certainly tried. Don Was has said he wishes he could've sold tickets to the recording of this album, just for the guitar parts. Because the guitar parts, some of them that never made it to the record, it was just so funny to hear that sound revived. There were times where I would take a Jackson and run it through a Rockman, which is as Def Leppard as you can get. It'd be a Jackson through a Rockman with, like, a [Marshall] JMP, and I'd start playing these kinds of Hysteria lines. But then you hear it back and you go, "I get it, but that's not me. That was so much fun, but that's not convincing and that's not sincere.'' So in the end it became this blend of my gear with the intentionality of the music of the past.
