Hey Dolemite,
I went to school for music in Iowa City. Lived there seven years. Have a drink at georges for me. Its on Market street.
To get an insanely overdriven guitar-wall-of-sound just double parts as needed on different tracks. This sounds simple and it is. try it you will dig it.
Other tricks. Shift the other guitar faders up on the chorus and use dynamics in your recording then your industrial music wont sound like crap because it will have ...voila ... dynamics. You can always try boosting about 3db at 2.5-5k works wonders. adjust your predelay of your reverb to match the room the guitar was recorded in. Measure the distance to the wall and figure in 2.9 ms per meter unless the room was hot when you recorded it. Then it will be a little more.
I can get better results miking nearly any guitar cabinet than I can get from a Pod or a Johnson or whatever. Put a mike right in the speaker cone and another one in the room and watch yer phase.
Guitars are not so bad. Recording Drums well is what makes it in my opinion.
