SUMI Guitar Parts offers high-quality products that "clear a certain level of quality," drawing on experience working at musical instrument stores and guitar construction & repair. These are steel long studs (set of 2) designed to fit Gibson (USA) guitars. These high-quality "Made in USA" parts are sourced from the United States. How about upgrading your Gibson regular series guitar, or using them as replacement parts for your Historic Collection series (also recommended in combination with an aluminum tailpiece)? ・Total length: approx. 39mm. Length under the head: approx. 25.4mm (threaded part approx. 23.8mm). Tailpiece ear gap: approx. 7.65mm. ・Color: Nickel-plated. ※Please check the dimensions carefully to ensure that the length under the head and the tailpiece ear gap fit your current guitar before purchasing. ※Please note that these will not fit Japanese-made Gibson-type guitars (although they may fit if the Japanese-made guitar uses inch-sized parts for Gibson). ※Anchors are not included. Shipping is free and will be via Yu-Packet (postal delivery with tracking service) only. ※To prevent any trouble for both parties, we cannot accept requests for other shipping methods without tracking service. #Aluminum Tailpiece #Gibson #Les Paul
