Instant purchase without comments is welcome! This is a general strings guide. Also known as a string retainer. Are you using a Stratocaster-type guitar and concerned about resonance? This one item solves the problem. Metal washers provide excellent stability. The screws also have a nice round head. Because the string angle changes, the tension becomes slightly weaker, making it easier to do string bending. Also, tuning becomes more stable. [Contents] Set of 2 * Please use the metal parts for height adjustment that you prefer, as they have different heights. ★-★-★-★-★-★-★ We do not offer discounts. We have multiple items in stock!
