This useful 2-piece bundle combines MusicNomad's innovative GRIP Drill Bit String Peg Winder and GRIP Puller tools to make changing strings and pulling bridge pins on acoustic guitars quicker, easier and safer. The GRIP Bit Peg Winder attaches to any power drill or screwdriver to wind new strings on tuning pegs smoothly and silently without scratches thanks to its rubber-lined design. Its contoured head fits most tuning pegs on guitars, basses, banjos, mandolins and more. The high carbon steel shaft ensures durability. The GRIP Puller makes removing old strings simple by allowing you to easily grip and pull bridge pins straight up in one quick motion. Its ergonomic rubber grip enables one-handed operation. The metal-free construction with rubber exterior protects delicate wood and all bridge pin types safely. Together these two tools form an acoustic guitar string changing bundle that takes the hassle and potential damage out of routine string maintenance. Their innovative gripping technology and protective materials speed up string changes while keeping instruments safe from scratches or dents during tuning peg winding or bridge pin pulling.
