A ring modulator, which is actually a multiplier, has two inputs, a 
"carrier" and a "modulator". The technique goes like this:

Monitor the X+ output

1. Set X1 control fully on
2. Switch VCA/Ring switch to "Ring"
3. Patch an audio sine oscillator (carrier) to the X1 input
4. Adjust the Z control for the best null of the carrier signal 
(somewhere around the 1 o'clock position)
5. Patch another sine wave signal to the ZMOD input.

At this point you should be hearing two sine tones which are the 
sum and difference frequencies between the two sine wave 
oscillators. Sweep the oscillator frequencies as an experiment.

Any audio signal can be used instead of sine waves, but they are 
best for demonstrating the sound.

Thanks for the info Grant. A helpful list member explained it to me offlist. The ring mod worked fine, I was just concerned that the toggle switch didn't seem to make that much difference, at least with audio signals. I'll experiment with the sine waves.
 
By the way, how's my Wogglebug coming along?  : )
 
Thanks again,

oh man  a cable got wrapped around my foot
and my box of modules flew off the  table and hit the ground
but all is fine
whew
