Ah, I forgot, did you try [expr~ tanh($v1)] ?

At first I assumed that you wanted to go beyond that simple distorsion and 
into more interesting forms of distortion. Chebyshev's are only useful if 
you want something that can also sounds like pitch shifts by harmonic 
steps.

I think that tanh is rather close to the physical behaviour of capacitors 
being strained, but surely not exactly that, and I didn't do the math to 
figure out what the real formula would be. (Did anyone try that ?)
