Made especially for Bigsby B5 users that have a standard Tele (4) wood screw, shortened hardtail vintage footprint. Strings glide smoothly over our patented hard chrome-plated brass saddles without pinching. Includes four 18-8 stainless steel oval #6 screws. Has string through body holes as well. Be sure to check to see if your guitar has the four wood screw footprint.
