[sdiy] "Audio" vs. "Log" taper

[harrybissell]

ah... you're not a guitar player i take it...?
nN AAt     e     e has it just about completely right... due to pickup loading,
cable capacitance etc the useful range of ANY pot is reduced to about
20% of rotation... which does not seem to bother many guitar players including
myself.

You might think that you could turn the amp WAY up and use the full range of the
pot.. but that is almost never the case in practice...

The ONLY place I can see taper being a real issue is in the reverse audio tapers
used
in Moog ladder filter resonance controls... as well as some others.  Here... it
is painfully
obvious that the taper is very critical to getting ANY range of variation between
low rez
and oscillation.

of course there may be other critical apps like mixing console faders etc...
