The AD633 data sheets are pretty complete, for making a multiplier.
All you need (and for tying into a modular you might not even need this)
is something to beef up the audio in, because to get best signal/noise
ratio you want solid input levels.
And interestingly, one of the inputs has more noise than the other
(forget which!).

For a free-standign ring modulator, you need an oscillator source as well, 
of course.
