I've got the 462. Used it years ago, then once I stopped using it, I never looked back really. At first it was "OMG this sounds like a pillow has been lifted off the speakers", but after a while I realized it made my rig sound harsh. I also have the plugin and messed with that a few times. Like stated above, it can work great at times if used lightly. I seem to recall it working well on bass guitar. But then again, this was like 7 years ago so maybe my ears just weren't as trained.
