Hi there,
Agree with the statement that the best you'd get is a
saw tooth. With guitar, I'd say to go the traditional
way: first turn its signal into something with high
harmonic content (asymmetrical distortion, waveshape
to taste) and then perform subtractive synthesis. I
guess what you're thinking of is a kind of fourier
resynthesis. But if you really use a harmonizer, you
would just get additional harmonically-related sines.
Maybe it wouldn't be a real saw tooth at best, but
more of a monophonic hammond organ...
Frequency shifters are interesting. But you'll only
get harmonically-related results by accident (or
dextremely careful design).
Greets,
Paul
