I tend to complicate reverb more than some...
I don't recall my fine details, as they do change...but I do occasionally get a bit involved too. I keep it subtle for the most part, but I may combine a few different reverb flavors, though I try and keep them compatible.
Vocals are almost always a plate of some kind. I've get some hardware units with my own plate presets that I configured to taste and set up as basic short, med, long...and from there I'll tweak them additionally if needed.
I also have some great plates in software that I've become quite fond of, one being the primary reverb plug from my DAW...but I acquired the Waves Abbey Road plates not too long ago, and they will surely become some of my go-to vocal plates.
For guitar leads, I tend to lean toward a medium hall reverb from my hardware units...while rhythm guitars will get maybe a small hall or plate...all depends on the song tempo and the density of the guitar rhythm.
If I have multiple rhythm guitars, I may leave some dry as a contrast to the wet ones.
Keys often end up dry, as I find they will mush out the mix very quickly otherwise...though there can be the occasional ballad where the keys work when they are bit mushy. If I did more ethereal, electronic stuff...then you can let go more with reverbs on keys and synths...but most of my keys end up being some organ flavor, often my old Hammond, which I split out L/R, so dry works best...and the other is piano, which I like for it's percussive quality on Rock/Pop stuff...so dry brings that out.
Finally....on drums, I've become somewhat enamored with the old EMT 240 plate unit I acquired a year or so ago. It has a sweet spot that really works great on snare, bringing it out but without excess, while simultaneously making the hat sit more favorably in the drum kit mix....it's actually interesting how it changes the actual tone of either the snare or hat, depending which is sending more to the plate, and it doesn't just add more or less reverb....if that makes any sense.
All that said...I am starting to try out more drier mixes, as that seems to be the current mix flavor in modern Pop/Rock...but I don't think I will ever give up on using reverb altogether. I do like it...but as I said, subtly is the key.
