Vintage guitars that were manufactured decades ago have consumable parts and other items that can cause problems with functionality. When parts need to be replaced, many vintage guitar users fear that the tone will change drastically. The hardness of reissue saddles varies depending on the part, and their properties are different from those of vintage saddles. Furthermore, to prioritize the beauty of the plating, copper is often applied as a base coat, which has a significant impact on the sound. The Raw Vintage Pure Steel Saddle is made from the closest material currently available to vintage saddles, eliminating variations in hardness, and is directly nickel-plated to make it even more similar to a vintage saddle. Of course, they can also be used as replacement parts for current reissue guitars, so even those who don't own vintage guitars will be able to enjoy performance that is closer to the real thing. RVS-108(10.8mm): This is the Japanese standard. It is compatible with Gotoh bridges that use 10.8mm saddles, as well as F company Japanese-made guitars.
