I spent some time this morning looking for some good Freeware VST distortion plugins. I've been interested in making my mixes sound messier and a little wilder and I find the distortion plugins that come with Cubase a little weak. They either don't mangle sound the way I'd like or they sound like a cheap metal distortion pedal, which always sounds lame to me. Anyhow, after trying out a whole bunch of them, the best distortion plugin I've found so far is Cyanide 2.0. It's really a vast improvement over the effects that came with Cubase, so I'm pretty happy.
