I'd been doing what most of you guys were doing as well, I understand, and just muting the room mics on Superior. However, last night I started screwing with them a bit after reading some of the Systematic Mixing guide on the commute home, and not only turned up the "close" ambient mic, but also enabled the mid and far mic and then threw a compressor on the room channel.
Sounds AWESOME for rock stuff. You guys are all smoking crack, everything just seems bigger and vibier and less sterile now.
i use the room a bit as well
