This set of six Hosco Mustang/Jaguar/Jazzmaster Bridge Saddles are in the modern Fender smooth barrel style. Their shape removes any problem of strings coming out of the slot during playing (perfect for upgrading old threaded saddles) and they are made from stainless steel. A set includes two 8 mm high, two 9.5 mm high and two 10 mm high saddles and all saddle widths are 11 mm so they will fit string spacings of 55 mm or more (they will not fit the Fender Professional string spacing of 2 1/16"), they come with intonation screws and springs included.
