This is a set of black (black chrome) parts removed from a guitar of the "Rockoon" brand, made by Kawai Musical Instruments around the mid-80s. These are old parts from the Japanese vintage era, so there are some scratches, but considering their age, they still have a nice shine and I think they can be considered beautiful parts. I have confirmed that the strap pins are compatible with the "Schaller" strap lock system. The fine tuner knobs are made of brass and can be polished with metal polish to a shiny finish, but I haven't polished them as it's a matter of personal preference. Please check the images for the condition and the contents of the set. The bridge, which has the "Rockoon" logo engraved on it, allows you to change strings without cutting the ball ends of the strings. It provides a natural sustain different from locking bridges, and keeps the tuning stable without compromising the good qualities of a Stratocaster type guitar! Rockoon brand often used Schaller parts, but I couldn't find any markings from the manufacturer, so I will leave the OEM source of this part as unknown. The stud pitch is the same as the Japanese Floyd Rose patent product, so "I want fine tuners, but I want a compact bridge" I recommend it to those who think so. As a side note, there are no markings on the tuner pegs either, but OEM products from "GOTOH" were the mainstream for domestic guitar manufacturers around this time. *Please note that the bridge may be disassembled from the body for shipping. The locking nut is listed separately and can be installed on the "Rockoon" brand neck without modification, so you might want to install it together. I also have other guitar bodies and custom parts for sale, so please take a look if you'd like.
