And about waveshaping, let me say that, for "big distortion", in addition to the tanh(x) and atan(x)*2/pi functions that I may have previously mentioned, x/sqrt(1+x*x) and erf(x) are quite cool. They aren't particularly modeling the behaviour of analog amps nor speaker membranes, but still, they're rather simple functions that appear everywhere in science.

These are great; thank you!
