This listing is for an Electric Guitar Pickup and Bridge combo.
This will work in some models of Fender / Squier Telecaster or Esquire that has a Humbucker cutout in the bridge position.
It doesn't fit everything though. The mounting screw dimensions are 80mm x 86mm.
It is from an electric guitar that I took apart.
It is in excellent condition.
Make sure to check the pictures before purchasing.
