Trent Reznor

1994 interview Guitar World - REZNOR: Almost everything was direct--there was almost no miking of cabinets. I just don't like that sound very much. It sounds boring to me. So we ran through a variety of preamps and speaker simulators. Our main preamp was the new Marshall JMP-1. But I didn't use the speaker simulator in it. I took the direct out of the Marshall into the Zoom 9030, employing just the speaker simulator on that.
