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.
