Music Nomad’s patent pending GRIP Winder has a built in dual bearing design that makes turning the GRIP Winder handle effortless, comfortable and super fast. The innovative GRIP technology smoothly slips over tuning pegs for scratch-free operation relative to traditional plastic peg winders. The contoured design fits virtually all tuning pegs both big and small, and a narrow profile prevents 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.
