This four piece set includes electric string winder tools with integrated string spreaders to speed restringing and support accurate tuning on guitars and ukuleles. Key benefits Save time and reduce hand fatigue: The electric winder spins tuning pegs quickly so you can change strings faster than by hand. Cleaner, easier string installation: The built in string spreader keeps strings separated and guided across the bridge and nut, reducing tangles and misalignment during installation.
