Just tried it, tested with a synthetic overdrive effect. The results look
plausible. but I haven't tried shaping anything with them.

The data is attached incase anyone wants to try building the waveshaper
out of the data. The ends of the curve are bogus, they would need to be
removed to get an accurate shape.
In the data file the first column is the input amplitude, the second is
the output amplitude.
I probably wont have any time to work on this tommorow, but I will have
plenty of brainwidth.
