I am, I'm just curious, sure it may not be the most exciting thing in
the world, but it's VERY small, and right now I'm after a very very
small foot print filter for a project.

I've been following the simple VCA thread, and an LM13700 is too big
for me, so I'm going to be playing with the single/dual transistor
VCAs.
