Thank you for the specific advice -Nathan Alexander. I will put reverb on everything because it sounds good but my lack of purpose hurts the overall mix of the sounds.
You aren't required to put it on
Everything.
The trick with reverb and
Contrast and mixing in general is actually
less is more.
When I say
less is more I mean that you've become very selective about which instrument gets lots of reverb, and which instruments are practically dry or just have a little reverb.
So when I say less is more I also mean you've got one big, frequency dense instrument with many thinner, aggressively EQ scooped, and high passed instruments.
The illusion of density and fullness is created through aggressive use of less when you could use more, and then finally using more on just that one instrument where you really want more.
In any one of my mixes I generally like to have one main instrument with lots of reverb and the rest significantly and comparatively dryer.
As I become less decisive about which instrument(s) are allowed to dominate that big,reverby space in my mix and which instruments are comparatively drier, then the perceived Front to Back depth of my mix shrinks and becomes more flat.
If you're not sure where to put reverb it could be because you haven't yet accelerated your ability to perceive space and reverb by deliberately setting one instrument as very wet in your mix and the rest comparatively dry (barely audible reverb).
That will create immediate contrast and you will immediately begin to notice what contributes the most to a Massive Front to Back depth in your mixes.
