Hello... what i'm asking is would this diagram basicly make a pickup that vibrated the strings or would it just make a weird feedback sound?

the principle for sustainers is more or less feedback

well, will it be a good feedback?
Depends on how it turns out. You may find you want to use a different piezo later on... or a different circuit. I say try it and see what happens.

you got that off project-guitar.com right? That sustainer project hasn't worked for anyone except the creator. It's not the sustain your thinking of, it's just, odd. If you really want to make a sustainer go on the forum and there's a 250 page thread on homemade sustainers which has come up with a very simple working sustainer design.
