interesting concept!
Hey JV,
I don't know if the panning idea will increase fidelity or not, but it's a cool idea. If you try it, please share the results.
Here's one "trick" that I use when I am capturing a song using voice and an acoustic/electric guitar recorded simultaneously:
Go direct into one track with the guitar (so the sound of the guitar will be isolated). And mic the voice fairly close onto the second track, but it will still pick up the "acoustic" sound of the guitar. So what you end up with is the voice and "acoustic sound" of the guitar on one track, and the guitar from the pick-up on the other track. And you can play with the mix from there.
When panning the tracks then you get a stereo field on the guitar which is nice. Then if you add a supporting track in the form of a 2nd voice or 2nd guitar part , the mix really sounds richer to me, than if recorded isolated.
Also, you could sing the song again onto another track, for a pretty cool effect. You want to try to sing fairly close to the original take (or you can throw a few harmonies in). If you are just slightly out of sync in places, it can add a "chorusy" effect.
If you are too far off it just sounds messy ;-)
Maybe lots of people do this already, so it may really not be a "trick" at all, or maybe nobody in their right mind would choose to do it this way (lol), but I have gotten some pretty good results with this method. I also like that the essence of the song is being captured as a "live" take which always seems to serve the song better to me.
I know this is the antithesis of what pro sound people recommend, in terms of allowing bleed into the vocal mic, but it really adds a lot of body to the recording (and i actually like bleed when things are balanced properly.)
Hope this doesn't sound too weird ...it's worked great for me at times and seems like something you might wanna experiment with.
Have fun!!
