I'm doing a mixdown for a folk band in my area that's getting signed onto a label here pretty soon, and it's just been fucking ages since I've done anything outside of electronic stuff and the odd dubstep-esque tune here and there, and I've never done folk before.

Honestly, the music is good enough to stand on its own, even if I did just a somewhat half-assed job on the mix, but I see this as a challenge to take on.
I want to limit myself and use little eq, no compression/limiting, little fx as possible and rely on how it was all tracked as to preserve the original sound and music. (I know, how stereotypical.) But I don't trust them well enough to record it all nicely, and I won't be able to be there to record it myself, else this would be a breeze. So, anyone care to share some experience and knowledge on working with folk/acoustic music, and hell, let's make it more generalized: anyone else currently limiting themselves on a project in hopes of improving and honing their skills?
