I just removed this from a new (used) guitar. Joined this site to see if anyone here can help me with what it is. My googling suggests it may be a Silverbird neck pickup wound by Maricella Juarez. As I am the opposite of an expert with respect to pickups any guidance would be greatly appreciated. https://www.seymourduncan.com/blog/latest-updates/seymour-duncans-prodigal-sons-the-sh7-and-the-sh9
