What I want is this: if I would have recorded two separate guitar parts and they are panned for instance L50 and R50 I want to use a single reverb plug-in on an FX track and use the sends to duck the reverb just behind each guitar, at exactly L50 and R50 in a dense mix. Now I could use the stereo version of the plugin and pan the sends in Channel settings > Sends > Panning for each guitar at the correct spatial position. However, the stereo reverb fans out across the entire spatial field…! If it’s panned L50 most of the effect can be heard at L50 but definitely not all. Maybe not surprising for a stereo effect but not a definitive solution for ducking the reverb exactly at the instrument’s spatial position.
So, an option would be to use the Mono version of the reverb plugin but this could only be panned L50 if I pan the FX track L50. I would have to use a separate FX track and plugin to get it R50 for the other guitar, which is not efficient (regarding CPU usage etc.). How can I send each acoustic guitar post-pan to a single bus that has the reverb on it? How do you commonly proceed in this case?
I don´t understand what exactly you mean by “use the sends to duck the reverb just behind each guitar”, but if you want the reverb from the L 50 guitar to be at “only” L 50 and the reverb of the R50 guitar to be at "only"R 50, you will need to use two mono reverbs FX tracks, with the Returns panned one R50 and the other L 50.
