Nice to hear about this VCA. I got to study it some!

UhHm... would you please elaborate on that topic somewhat, I'd like to hear
that story about the Wahwa pedal if you'd care...

BTW. Input protection is a good thing to have, especially if you run stuff in
an environment where the wiring of chassi to either of the plug poles seems
to be accepted practice among guitarist (shrug!!!).
