Is there a way the pedalshield could be used to kill feed back when being used with an acoustic guitar?

I have a nylon string acoustic with a contact mic and while trying to use it with my computer and speakers on a lowish volume - I get feedback. Is it possible to code a way that pedalshield would kill the feedback, without me having to use headphones?

Hi, so the mic catches the sound from the guitar itself and the guitar amplified through the loudspeaker... I cannot imagine any way to reduce it... maybe with the trim pot VR1 you can try to reduce the input stage gain?

Your problem is a common one and it could be done doing some echo cancelling algorithm, but it is pretty difficult even using super high quality DSPs.
