Thanks, mettulus. Good ear. I actually used the Blue Tubes stereo widener thingie on the main vocal bus (which also has the main harmony in it as well). I thought it made the vocals fuller sounding but yeah... that may have been a bad idea (or have it too wide). Since the harmony is going through it too it might be exacerbating the issue. Maybe once I get the delay in there and split out the harmony I can yank the widener. Then again those actions themselves could cause the same types of issues. I'll have to futz with it. Maybe I should try some saturation on the lead vocal to make it fuller instead of spreading/delaying it. As I said that aspect was kind of half finished and honestly, since I'm not really used to mixing with vocals, especially female vocals (part of the reason I chose this as my "test" project), I wasn't exactly sure what I should try. I'm actually glad now they are low enough to have stood out because now I've got some good ideas to try.
I definitely like the idea of keying one set of the guitars to the vocals (and I think I know exactly which pair will get it if I go that route). As for the dynamic EQ thing unfortunately I don't own one of those (I'd like to get that Melda Spectral Dynamics one at some point) but I also know an Anderton trick of using the old Cake Analyst to write freq tracking automation that can then be tied to an EQ. It's a bit of a brain bending trick but I've always wanted to try it.
I am kind of thinking though that this version may be a little misleading without the 20hz hi pass filter on the master. On my local versions whenever I've cut out those low rumble freqs everything gets a lot clearer. As I said though I considered that more of a mastering task. I did kind of keep checking that as I mixed. I set up kind of a fakeout/light mastering set up on my premaster bus to see how it would respond to things like the hi pass, compression, tape sim, etc and as I worked I kept a/b'ing the individual effects and all the effects as a whole.
It started out that all those effects helped the sound. As I mixed and tweaked and fiddled they all became less and less helpful until eventually the mix sound better on its own... which I took as a good sign the mix was getting better (everyone keeps saying you want to do as little as possible in the mastering stage).
The only exception was that hard low cut. It always helped clear up the mix. Since I did cut out all the ultra low freqs on all the individual tracks it wasn't as bad a build up as on my previous efforts but of course these things still buildup naturally on a big project I suppose and I know that's just something you're supposed to do... and THEN use a bass maximizer or multiband comp to fatten up the GOOD bottom end frequencies (instead of all that useless below 20hz crap).
When I did actually do my own "master" though things started getting a little off kilter (some parts got louder than I wanted, others quiter than I wanted... like just some of the dynamics in the song got screwed up). The bottom sounded great though and when it was staying even as I intended it all sounded pretty crisp.
But that's why I'm not a mastering guy. I'm guessing it's a multiband compression type task (MB's still screw me up) or even some automation of the mastering effects needs to happen.
Anyway... thanks for checking it out. You've given me a lot to consider. I'm thinking I'd better get this version off to Danny as well just to see what direction he thinks I should be going in too before I futz it up.
Cheers!
