A dual ringmod eh, that's like 2 ring mods in one module, eh?

I recently built a passive 'hex modulator' based on the passive ring
modulator circuit at    http://www.synthfool.com/ringmod.html

What this does is takes THREE inputs, using 3 mouser TM018 transformers
attached to opposite corners of a hex ring of diodes (picture a benzene
molecule...)  The inner centre tap of one of the transformers goes to
ground, and the other two taps go to left/ right outputs.  Because of
slight assymetry in the currents induced by the three inputs, you get a
nice but slight stereo spread of the ring modulation effect.  

Now, you can get some pretty wild noise out of a normal ringmod, but when
you put three inputs together, the results can be even stranger...

Hmm...  you can also get interesting effects by wiring capacitors or
inductors in parallel with one of the diodes.
