You can do as much or as little to any sound you'd ever want to achieve, give the understanding of the program you are using.

That being said, you'd have to use all available means to get the desired effect. You're only limited by your knowledge and will to manifest your creativity.

Back to reverb processing, I have a few reverb units (limited to 8 inserts but that's more than enough) going on at once for specific textures. I normally tame my reverb units with an eq (low cut/ high cut) so that it won't interfere with the super and sub part of the song.

some times i have reverb busses(individual channel pre fader) being routed to my main instert bus(mixer) while having an eq on the that channel buss shaped to enhance the frequencies that i want out of the reverb.

It's a great tool that adds characteristic, depth, and texture to any track. Shape it with EQ, haven't used compression a whole lot outside of taming an entire sound, and any other effect that you can think of.

Lastly, consider a width control tool that will allow you to make things more mono or more stereo to enhance the precision and accuracy of the reverb buss (mixer) or the signal prior to the reverb buss. This helps with a lot of tools such a phaser, flanger, chorus from being all over the place and muddy when you combine reverb and stereo tools. The trade off is an unclear image until you control the width of one component of the stereo image you've created.

Thanks for the reply!

The tip about the width control seems to make a lot of sense, I remember constantly putting really wide tracks into the reverb buss and then making the reverb wider than the original synth and it sounded like absolute muck most of the time.

I've always wondered about adding too much reverbs that are different to one another, would this not create an unrealistic space? I know it can work in favour of depth but other than that, what difference does it present?

The main component is this: mixing the sounds with taste and precision.

Using any tool with out understanding is a no no. Depending on what you're doing, how you're doing, and where every thing eventually ends up will decide if it's "realistic" or not.

I mean, they used plate and spring reverbs, the sound they got out of that was from sheet metal and coils. Do you think that's a realistic space? Maybe not for a human, but it gives a certain sound that was desired.

Back to basic principles to answer the question, you have to understand your tools and tailor them so that it fits. Quite honesty, some times it just doesn't fit!

I will suggest to do some research on reverb history.
