My booth is ~ 2,30 m x ~ 1,5 m inside ( 2m hight ) with one corner cut where the doors are. That thing is about unusable. Will be taking off some absorbtion from the walls to regain some highs in the the low-mids-to-sub-bouncing-waves mess, and will try with very close miking, but you´d never do any recording in there that would finally yield airy results, I say no matter what EQ, delay / reverb ... whatever tool.

The early reflections mudden up the sound from mids to bottom and you end up with cutting out most of the body to escape the nasal image while in the same time the highs can´t unfold in such small space.

I think that it needs at least some distance for the waves to travel, and also that especially the room behind the source needs to be reverberate / delaying. ( That is the spot where I´m thinking of to remove absorbers.) Could it be that you need "rudimentary" ambience in the recording at least to get best results afterwards with FX echo?
