[sdiy] Simple clickless FET mute switch?

[Mattias Rickardsson]

Thanks guys for the suggestions of Vactrols, VCAs, etc. They surely
make a good clickless mute, and can double up as a level control as
well.

However, I'd rather use 32 cheap FETs than 32 VCAs or 32 Vactrols,
that's why I'm still looking for such a solution. :-)
