This "Nail the Mix" video features engineer Tue Madsen demonstrating the mixing process for the guitar tones on TVSoR.
This interview with drummer Tomas Haake gives some good background on their approach to recording this album:

"...on their eighth album titled "The Violent Sleep of Reason," the group has once again redrawn the lines and shifted expectations. The 10 songs were recorded virtually live, which is an approach the band hasn't used for many, many years. Drummer Tomas Haake says, "It's something we had done but it's certainly been more than 20 years. Either it was the "None" EP from '93 or "Destroy Erase Improve" from '95 that was the last time we recorded live in that fashion where we recorded several instruments simultaneously. We wanted to old-school it and get back to that..."
"It's all live takes and yeah, that makes for a difference in sound and in vibe also. Because you have the human flaws if you will that are in there now [laughs] and they're audible. To a certain degree, it makes it a little sloppier if you want to use that word but at the same time it brings an energy that was inherent in all the music we grew up listening to like the British Wave and the Bay Area thrash and all of that."
By recording live, did it change the way you approached the drums?
"It didn't change so much how we approached the drum recording as much as it did the guitar and bass. This is also the first album in many years where we actually used amps and miked cabinets like old school. So the guitar setup was five cabinets with five heads: Orange, Marshall, Mesa Boogie and different heads for each cabinet and each cabinet miked so we could pick and choose and change the guitar tone a little bit depending on whether it's a sludgier song or a faster paced one. So there's actually a little bit of difference in the guitar sound throughout the album, which is something we haven't done in a very long time."
On the earlier albums, the guitars and bass weren't recorded with amps?
"On "Koloss," "obZen," and "Catch 33," on those albums it's the same sound for each song pretty much. You've got the exact same guitar setting and tone on everything. This is a little different in that sense too."
