D'Addario Accessories, part of the D'Addario family of brands, is known for innovative, problem-solving, quality musical accessories, and this is no exception. The D'Addario Accessories Drill Bit Peg Winder attaches to a cordless screwdriver for faster and easier string removal, although it is not recommended for tuning up new strings unless you're very careful! With high quality polymer construction, the peg winder can accommodate vintage to modern guitar and bass tuners in a one size fits all design while the nickel-plated steel shaft will resist wear for countless string changes.
