Okay this could help .

Listen to Bon Jovi:

Dead of Alive
Living on a Prayer

Those 2 tracks have the main Vocal sitting completely wet ( Wet recording non boothed)

You need to add a MONO reverb in the end of the Vocal track strip, that mono reverb has to have DRY/WET mix controls and bring the wet section down and only allow 30% through of the wet.

Then send that Vocal over a Stereo Reverb ( but change the width to 80%)

Now listen ( in reaper hit the MONO master button and click L MINUS R= difference of the stereo summing)

This will allow you to check the Vocal's depth inside the stereo reverb as the Mono reverb will not show up in this listening mode, the mono reverb will only be heard when you switch to listening the master to stereo mode L+R.

Using a Phase Meter plugin is critical when working with stereo reverbs as they are not the same as when sent to outboard mixers, the image is not the same no matter what anyone tells you .

I will be making a tutorial soon on using the Dry Vocal Fader to control the Vocals positioning inside or outside of the Reverb Send. This allows you to put the vocal inside the reverb depth or bring the vocal up front outside the reverb all using the Vocal track fader just slightly without messing with the Reverb.
This is all using Phasing and this saves you insane amounts of time placing the vocal in the reverb without jumping back and forth between the vocal track and the reverb settings WET/DRY MIX or even send level!!!
