I was looking at simple VCA circuits (I want popless muting for some communications gear, so a slightly ramped VCA would do but distortion isn't a big problem), and ran across this:
How exactly does it work? I would have thought that increasing the CV would turn on both the pass transistor and the shunt transistor. There's obviously something clever that I'm missing.
