[sdiy] passive ring modulator transformers

[Tim Ressel]

Hi,
I like them both. A clean ring mod aka 4-quadrant multiplier is nice and 
clean and I find most versatile. An XOR ring mod on the other hand is 
dirty and has more of those 'am radio' effects we all love. Being a 
modular synth guy I get to have both.
