Thanks! Good to see one person who knows what he's talking about. There are indeed 3 rhythm guitar tracks (hard L and R, and a centre one that's automated to come up in the appropriate sections). There are also 3 tracks with reverbs etc. that I've used to emulate the feedback around 10 seconds into the track, and at the end.
Not much post-processing at all. Eq is a hi-pass at about 100 hz, and a 4db narrow scoop around 200-300 hz to remove some mud and help the snare cut through. Then, a multi-band compressor to tame the low chugs (very essential, with that much gain and low end). I'm running a saturation plugin on the master bus to glue everything together, but it's adding a bit of fizz that I dont like.
The cab is a Recto OH, and one one of the Ubers in stereo. I'm posting from work, so I can't remember the exact settings, but can post later this evening. Or, I can share the patch later, if you like?
