String Retainers (also known as string trees, string tees and string guides) are used on the headstocks of Fender®-style bolt-on necks. They are available in a range of different styles and colours but all do the same thing, pull the strings down on a sharper angle over the nut, creating more force on the nut slot and reducing the chance of string-buzzing. Some guitars use two String Retainers, some only use one. If your guitar only uses one just use one out of the set. - Modern Strat® or Tele® style - Set of 2 (RG15 & RG30) - Chrome plated - Includes 2 mounting screws - Includes 1 low + 1 high spacers - Made in Japan Gotoh guitar and bass parts are some of the highest quality components available.
