Music Nomad's GRIP Winder has a built-in dual bearing design that makes turning the GRIP Winder handle effortless, silent, and super fast. The ergonomic and non-slip grip handle gives you total control and comfort, and the innovative GRIP technology smoothly and silently slips over your tuning pegs for a scratch-free and clank-free operation compared to traditional plastic peg winders. The contoured design fits virtually all tuning pegs, both big and small, and the narrow profile keeps you from hitting close-fitted pegs on 12-string and electric guitars. It’s perfect for electric and acoustic guitar, bass, banjo, mandolin, ukulele, and orchestral strings, and it uses the highest quality materials, including a carbon steel shaft. Changing strings just got a whole lot easier.
