Ok, I’ve been battling this all week now and I’ve tried everything I can think of to fix it but nothing seems to work. To start at the beginning, I’m tracking heavy distorted rock guitars. I started out recording two passes direct(actually, it was more like 800 passes comped down to two), then re-amped them through a dual miked 4x12 (57/421). Both mikes are about the same distance off one of the speakers. Nothing was changed for each pass. This gives me two tracks of one pass and two tracks of the other. Panning both sets right and left sounds great(or good enough) but collapsing them to mono sounds like a flanger with the volume dropped. Obviously, this is comb filtering but when I zoom in on the tracks, everything looks to be in phase. What am I missing? Is it possible to have comb filtering occur when the signals look to be in phase? If the signals where not perfectly lined up, would it not be possible to just move one of the tracks and line them up manually? I do that with drums and it seems to work great. I still have the DI tracks so I can re-amp them as many times as it takes but I would like to know what I’m doing wrong before I try it again. Thanks.
