Operation appeared identical with either.

Question:  Has anyone here actually ever used one?  
If so, on what? 
And what did it do/sound like?

Basically, I want to know if it would be worth my trouble to put a
"real" one together.  Right now, it's just on a solderless breadboard.
I can't see this being much good on my FatMan since I have other ways
of generating the 2nd harmonic that this produces.  Probably electric
guit*r?

I really need to finish my Voltage Controlled Noise Generator.
