Re: NiN Guitar Tone
I found an old gutiar magazine recently where they interview Reznor just after he finished recording downward Spiral. Apparently a lot of the guitar on that album was record direct, A Marshall JMP-1 preamp was plugged into a little zoom multieffect unit (Trent didn't like the speaker sim on the marshall so used the zoom for that) and then into the desk. Lots of the guitar was layered like a million times and most parts were bounced out to analogue tape.
That doesn't really help you much though...
Ummm sorry, can't help.
