First, it can be helpful to think of reverb in primarily two ways
- realistically (what you speak to above) or
- creatively
For the
realistic use of reverb, i.e. simulating the room you are recording in (or imagining thus) you are usually talking about very small size of reverb. Consider for example that huge concert halls may have just 1 or 2 seconds of decay. For a studio sounding recording, you are usually looking at less than a half second. And you can simulate depth, as you note, front-back, with just a tiny amount of mix level.
But why
would you or
wouldn't you bake that in in a DI scenario? If it is a pretty negligible effect for that use, what's the issue?
Pedal reverbs are certainly available now that can compete with plugins, but, if you're trying to simulate a real room, that would mean everyone would ideally need to use the same pedal with slightly different settings to give you the same room, with, e.g. different predelay and eq (and the eqing the reverb only is often not an option on pedals). OH and including using that same pedal on the drums if recording live close-micd drums
Second, I find people don't have a good intuitive sense of how much they will need. If you're trying to get a tiny level just for depth and cohesion, what you need is an amount you can barely hear. BECAUSE, once it is run through several layers of compression and limiting, you will hear that negligible amount, just barely. Said in another way, the amount of 'reverb' you need for cohesion and depth is hardly
perceived as reverb, but if I were to A/B the sends I use for this you would instead get a sense of where things are in the room.
All in all, much easier to apply in the box to things going DI and it avoids some problems.
On the other hand, if you are micing an amp, recording in a good room and using the actual room reverb, I may bake the (again very subtle) reverb in. I've also often recorded DI direct and repedal'd reamp'd for that, in the same room as the drums. But I can't emphasize enough that I'm talking about very subtle reverb, i.e. I'm talking, not adding any effect, I'm just talking having a room mic in addition to the close mic that ill probably put at like -20 or 30 dbs in the end.
For the
creative use of reverb there are some different considerations. Your pedal settings may be unique and may be effectively interactive with the performance. Still, there are still clear mixing advantages to having a clean DI AND a wet DI to sculpt clean fundamentals on bass. Again, people still sometimes misestimate how much reverb mix you might need because they aren't anticipating the tons of compression used in modern recording. So recording two DIs would usually be my preference, clean and wet.
That's also though assuming a set and perfect performance. If you are doing any improvisation or might make mistakes and might edit a best comp, just
monitor with the reverb, and record a clean DI, and once the performance is edited, use a reamp box to repedal.
