Really nice breakdown of this plugin. The name always caught my eye but I could never get how it was supposed to be used! Thanks!

To add a few plugins to the list. I tend to use the Calf Suite a lot: Calf Vintage Delay, Calf Reverb and Calf Compressor are a must. For weird sounds I love Steve Harris' Smooth Decimator and Calf Filter (playing with resonance controls).
