There is no mixing trick to cover up poor vocal technique, first of all. Second, the same old notes in about 8 different bars is very repetitive, so I would actual experiment with low growls to see if that sounds any better (to yall, of course). When putting vocals into a song, you ideally want to keep the raw tone of your voice that the microphone picks up without messing with the EQ. You can do some minor adjustments to get rid of any super low end bass or bring out your voices natural attributes, but you don't want to edit your voice into sounding not like yourself. If you like the telephonic tone, you can more than likely accomplish that with simple low/high pass filters.
The way I keep my vocals from clashing with the guitars is just to put the guitars on separate sides and put the vocals in the middle, so the vocals have their own space in the sound wall and the guitars help to carry them along. To put it simply, just saving the center space for the voice and bass. So when listening it kinda "looks" like this to the ears:
Guitar 2 is non-solo lead guitars and Guitar 3 is general rhythm guitars or backing guitars (guitar 1 is what I refer to as the solo guitar or spotlight guitar, which usually goes right around the vocal space when there are no vocals at the current spot). But this is my personal method, some other people may have different mixing techniques. And no, you shouldn't have to fade back the guitars in the middle of the song to make room for vocals.
The instrumentation is very nice, by the way. Nice and heavy doom.
Thanks, that was actually a little helpful.
Only thing is, much of this isn't in fact already mono. The kick/snare are like 30%/40% right. The bass is 30% left. Almost everyone says leave them in the center, but I've heard QOTSA pull off just the opposite really nicely, and I carefully listened to Candlemass's From the 13th Sun, and the kick, snare and bass also are not centered perfectly. The guitars I recorded were pretty conventional, two high shelved at 100% L/R and two cleaner but crunchy tones 70% L/R.
I've been putting the vocals at like 20%-30% either direction.
Another thing worth using is a little bit of compression which will even out the volume of the vocals pretty nicely.
I actually compressed both a lot
