I'm not the biggest acoustic electronics guy, so I though I'd run this past you guys: A friend is having an issue with his Taylor acoustic. Ever since he got it, it sometimes had this weird pingy sounding overtone ringing out periodically - on the G, if I recall correctly. He's taken it in on several occasions, but never to any real satisfying result. Well, it's doing this all of the time now so he has taken it into the shop. He asked the tech what brand to go with if he were to replace the electronics totally, but the tech apparently isn't allowed to make recommendations. It's been though three visits to the tech (that I know of), and they haven't been able to fix it. He mainly uses the guitar for personal playtime, but he'd really like to play it in a weekly worship setting - since that's what he bought the silly thing for. Any ideas what could be causing it (is it even the electronics)? If you were you completely replace the stock electronics in a rather nice Taylor acoustic, what would you go with?
