Hi all I hope this is the appropriate forum to get help with my problem. I have a martin acoustic that has the Aura preamp in it. recently its developed extreme feedback. When playing or at least touching the strings there is nothing. however if I lift my hand from the strings a humm starts that gets louder and louder until its unbearable. I simply touch the strings and its gone. it happens with any amp I have tried. And those same amps I have used for years with this guitar and no issues.

Any idea where I start to troubleshoot this problem?

Thanks in advance
