Some help please!

Im pretty new at this electronic lark and i was wondering ive built a passive feedback loop and was wondering if it would be possible to
add in something to allow me to alter the signal of the loop/guitar with my voice or a contact mic like an expression ?

Can it be done and if so what should i use ?
Would a cv-in work like in the modified frequency analyzer

anyhelp would be greatly appreciated
cheers

The passive feedback loop uses no modulation source like that, so it wouldn't really be possible.  However, if you wanted, you could add a second input to it for your contact mic.  The reason that ring modulators can use external things to modulate them is that a ring modulator is simply one source modulating another, while a feedback loop is something completely different-it's the return of some chain of effect's output back into their input, which when the system has gain, causes oscillation.  If you wanted, you could build in a ring modulator ot your feedback loop but that is no easy task.
