It may be subtle, but putting the A-type on drums, the S-Type on Guitars and bass, and the N-Type on vocals is a great way to work. I also have the NLS Summer, which has some awesome models, such as Spike's SSL Channel 29 on guitars, or Mike's Channel 2 on a snare, but I recommend Console emulation on every channel! Sonar has the A-type, which Waves doesn't (oddly enough). What is the A-type? Modeled after a console with amazing transient detail, obviously. Try it on a snare and push it.
I believe the A type is supposed to model a Trident Series A console...?
I find I use the CE on essentially every track, but not as often on my sub groups... I like to use the N type on most things... Guitar, bass, drums, vocals, and the S type on keyboards, but I have occasionally done differently... I've used the A type a bit more selectively... I like it for some guitar sounds...
When I mass switch them, the difference is very definite and I prefer the sound with them than without... My sounds seem to be a bit thicker... And the type of grit I get from each seems very related to my memory of working real boards of the respective names...
Much like the quad EQ... They may not be spot on replicas of the hardware, but they do resemble them enough to be beneficial (to me)...
