Does Sphere technology model nonlinear distortion of microphones?

Yes, it models the subtle harmonic characteristics of tube and FET mics, although it does NOT model the full overload characteristics. The Sphere microphone is designed to have a large amount of headroom and dynamic range, so it can handle very soft and very high sound pressure levels. Our approach provides maximum headroom even if the original microphone being modeled doesn’t have as much headroom. We believe this is a major benefit of the technology, since an overloaded microphone is rarely a desirable thing.
