This is an aftermarket product imported from overseas and is not a genuine part. However, it is very carefully made and perfect for enjoying a vintage feel. It is made of stainless steel and chrome-plated. Like the original, the string spacing and height can be freely adjusted. The base is rosewood and has a slight curve to match an archtop body. The back is stamped with "Made in Japan," but it's probably not made in Japan (lol). I think this kind of joke is also interesting. An adjustment wrench (black or chrome) is included.
