I played with my Serge Wave Multipliers and Waveshapers today. One of the 
Multipliers will add odd harmonics to a sine wave while another adds even 
harmonics -- similar to what Thomas is proposing. I found that adding even 
harmonics was far more successful (I got great octavia sounds and a few nice 
"Strawberry Alarm Clock" type sounds) than adding odd harmonics; way too much 
"hair" on the attack phase.  I was also able (as always) to get some great 
bizarre sounds a la Pete Cosey (re, Miles' "Agharta" and "Pangea" albums)! 
And I noticed that an important change in the sound happened when adding VC 
from the envelope follower.

Unfortunately, with so many jacks, pots and possible ways of patching, it 
presented too many options (most not really conducive to basic guitar type 
distortion). I do however think that some study of Wave Multipliers in 
conjunction with basic fuzz boxes could lead to a number of different timbre 
modulators which could serve different functions in a modular setting.

I tried the link too Ric's timbre modulators, but it failed each time. Has 
anyone else gotten through? Maybe Ric's ideas could help us too.

I'm also wondering Thomas, if your list of fuzz tones (Big Muff Pi, Fuzz 
Face, Foxx and Tube Screamer) would be your wish list of distortion devices?

I'll check out the Wiard site next.
