[sdiy] 1 transistor vca (diode ring)

[tomg@efm]

Hey Paul.....Here's a 1 transistor vca based on the korg
770. ( I think it's the 770? I did it from memory..)

It's not very good, but it does work. What's wrong with it? 
Well......First of all it's not really ready for use..It needs 
some amplification ....say x10 on the output but that screws
up the 1 transistor thing and there is some distortion at low 
levels, about like the hex-vca....but!...what about that? You 
can build a 1 transistor  vca!!
