The D'Addario Ergonomic Peg Winder with bridge pin puller is
precision molded and specially designed to fit virtually all
guitars, basses, ukuleles, banjos, and mandolins. Unlike most
other peg winders, the D'Addario Peg Winder is ergonomically
designed and built tough to withstand years of use. A great way
to have easier and faster string changes.
