Of course, fixing the problem in the source project is what you want to do, but there is an interesting new product out there that is designed to remove reverb from completed tracks. The reviewers think it is not 100% perfect, but amazing nonetheless.

Peace.
PS They tried it on an old REO Speedwagon album and nothing was left but a click track and somebody humming.
