[sdiy] Audio taper pots

[Mattias Rickardsson]

I think it's extremely important to avoid linear scales on parameters
that are not experienced linearly - mainly since it's so easy.
Otherwise you'll end up with something that reminds of the hopeless
response of the volume sliders on cheap old plastic radios... where
almost everything useful is within the first 20%. :-)

Shunt it like Mark suggested, probably with an even smaller resistor
(around 1/5 of the pot value). This is all you need:
