Freeverb3

[tinga]

I never tried this pack before, 6 reverbs, stereo enhancer, compressor, limiter.
The quality seems to be very good, some ppls say that the gui is bad, I just find it very clear, I'm not fan of vst like christmas trees.

My favorite IRs are at: http://fokkie.home.xs4all.nl/IR.htm

Lots of unusual choices, speaker models and such
