Christortion

"Christortion uses a Chebyshev polynom waveshaper to excite harmonics of the input signal. Each harmonic can not only be adjusted surgically in dB but also the phase of each harmonic can be inverted. With this concept, you have a very wide range of distortion that can be produced.

The plugin itself is donationware. You can still use it and share it for free, but I would be very happy if you donate some money." - Christian-W. Budde
