Guitars sound out of tune and weak. Bad tone IMO. And I get heavy, clean, full-sounding results from just single L/R. I think quadtracking is just silly. Drums sound good.
Could be phasing. Just try this. Do one take on the left as tight as can be played. Strip Silence it, align the beginning note of the guitars to the beat and use flextime to align the rest of the section, then continue until the take is edited. Go for the left second take. Repeat. Mute the left tracks, record the right, repeat, and repeat. It's tedious, but it works.
Why dont you try lecto and some IR's and the edit as you go method on Logic.
