This is an aftermarket product imported from overseas and is not a genuine product. However, it is very carefully made and perfect for enjoying a vintage feel. It is made of stainless steel and gold-plated. Like the original, the string spacing and height can be adjusted freely. The base is rosewood and has a slight curve to match an archtop body. The back is engraved 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 is included.
