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 ?)
