Fuck, record looks pretty nice.
I was thinking the same...
isn't the center at 63 or 64 ?
Anyway yeah, 100% hard pan is good for rythm guitar if they are playing exactly the same thing, it will widen your sound and make room in the center for snare overheads and vocals.
Eq can be applied on the buss, it's supposed to be a linear process so EQing each guitar or the buss where are sent both guitars gives the same result.
Compression is not the same, it's not a linear process. On a buss it would compress also the Right guitar if the left one hits it, whereas if it was only on the right one it wouldn't at the exact same moment.
So the answer is :
- EQ where you want because it doesn't change a thing, on the bus it's fine
- comp where you want, but on the buss is usually good unless you wanna have a particular treatment for each guitar (like cleaning each of them with a multiband compressor to tame their lowend or something like that). Usually, putting a comp on a buss (drums, guitars, vocals, master track) gives what we call some "glue" because it affects all tracks in the bus the same, giving to you ear a more cohesive process, more natural too. But of course it depends.
Precise answer : you can EQ and comp on the bus if your tracks are ok. If they are a DI and you use an ampsim, you have to put one on each guitar, though, and then use a bus to EQ/comp.
As a note : a "fader" is only the physical stuff you move in a line to control the volume, it's the "object". What you are talking about is a "track".
EDIT : dunno if the sound of SSL 9k in the tracks of Record sound real, but they did exactly what I dream of : showing real-looking tracks of an SSL or Neve -like console directly native into the daw. Too bad this "daw" seems lacking too many features including... vst. It's garageband by PH.
