On the whole this is probably one of my favourite drum sounds so far, I think. True, it does feel like it needs 4-5dB of 'air', and its sense of size/sustain is perhaps not as well-developed as some others, but I really like the snare tone, which strikes a good balance between power and brightness, and the kick, toms, and cymbals seem to get on with the job in hand without fuss. There's a nice understated sense of blend, and I don't get that slight impression I've had with some previous mixes that the kit's been overdubbed one instrument at a time. I'd perhaps still tame the kick's click a little for the verses, and add perhaps a fraction more snare sustain and blend, but the bottom line is that this feels like a solid raw sound upon which to base any fine-tuning. As regards increasing sustain, you could do with some drum-buss compression, and probably master-buss compression too. For size, it's room reverb of some type I'd go for, but not anything too long -- you want the acoustic 'frame' around your sound, but not any enormous tail.
It occurs to me that something has been bothering me about this set of multitracks for a while now, and although it affects most of the mixes here, I've only just put my finger on it this minute, so I'll talk about it now and hope that people will also take it as a more general point. As huntermusic commented in his response to my critique of his mix, the bass guitar part here is a bit unusual in that the amount of low end it contributes to different parts of the track, and the frequency range in which it makes its low-end contributions, vary a good deal from section to section. As a result, most of the mixes so far aren't really very consistent in terms of the low-end of the combined bass/guitar sound. If I were doing a mix of this track myself, I would almost instinctively mult the bass across several different tracks to tackle this, but I suspect that most people haven't been doing so, and are therefore struggling with a well-nigh-impossible task of finding a bass-processing chain which works equally well throughout all the song sections. The place I notice the inconsistency most is in the middle sections, where the first middle section almost always feels a bit bass-light compared to either the preceding or following sections.
I love the guitar sound in the verses, but it's eclipsing the vocal, which I figure is probably counterproductive. However, the fault here is with the vocal timbre, I reckon, which sounds to me like it's suffering some kind of unintentional phase-cancellation -- it's strangely hollow and crispy in that characteristic way. Have you tried to parallel-process this vocal and inadvertently defeated your software's plug-in delay compensation, or something like that? Irrespective of what the root cause is, though, I'd go back to the drawing board on it, because I think it's letting the side down currently. It doesn't bug me nearly as much in the choruses, though, except on the more exposed 'feel like a failure' end tag. (Incidentally, I really like that delay spin, which is great for the momentum into the middle-section!) There is, however, an unpleasantly prominent 12kHz peak in the sibilance which needs dealing with. The BVs are also unfortunately not quite working for me either, because although they're commendably wide-screen, the cluttering side-effects of their long echo tail mean that on balance it's not good value for money.
The secondary guitar in the choruses is disappearing almost completely in mono, and I suspect that it's on account of some kind of polarity-based stereo-widening effect. Now while I'm fine with using a super-wide 'outside the speakers' sound for peripheral parts which are inessential to the mono presentation, I personally feel that the secondary guitar is more important to the song than that. The mono-compatibility issues don't stop there, though, because the mid-section guitars, the snare, and the backing vocals all dull considerably on their way to mono, and the cymbals (especially the ride) seem to lose a good deal of power and air -- check out the outro section in particular to hear the kinds of things I'm talking about. The general mix tonality is pretty good (the general lack of 'air' notwithstanding), but things do nonetheless get overly abrasive with the thicker guitar texture in the mid-sections, I think, and some EQ tweaks there would be welcome.
You've clearly put quite a lot of effort into expanding the sonics with effects, and with a certain degree of success it has to be said. However, my opinion is that you're pushing this angle a little too hard. I don't think the kind of size illusion you're looking for can actually be created by send effects alone, and by trying to take things that far you're beginning to muddle and distance the mix as a whole. Instead, take the effects as far as you can without their side-effects becoming problematic, and then look to make up any shortfall in other ways -- compression, overdubs, double-tracks, or whatever. You need as many strings as possible to your bow if you want to dramatically pump up a texture like this.
Anyway, thanks for submitting this mix -- and for finally alerting me to the bass issue that had been lurking on the brink of my consciousness for so long!
