Since the early days of Japanese-made guitars in the 1960s, Yamaha has developed numerous original models with a strong sense of individuality. In particular, from the 1970s onward, they have produced hit models such as the SG and BB, earning high praise both domestically and internationally, especially among fans of Japanese vintage guitars. This latest arrival is an "SC-1200," which, based on its serial number, appears to have been manufactured around 1978. It was the top-of-the-line model in the new series launched around 1977. 【body】 The total weight is approximately 3.55 kg. The body (wing material), which has a shape reminiscent of the ST type, is made of alder and finished in Yamaha's familiar stain color. There are some scratches, dents, and tarnishing on the metal parts, but the paint still retains its shine and is in remarkably good condition considering its age. 【neck】 The neck is a 5-piece maple/mahogany construction with a rosewood fingerboard. It features a neck-through design. There is a large dent on the back of the neck, around the 6th fret. The tuners function properly, although there is some slight variation in the winding. The nut has been replaced in the past, and the frets show only minor wear, resulting in good playability. The nut width is approximately 41.9mm. It features a sleek neck shape typical of Yamaha guitars. [Electrical System] The controls are very simple, with just one volume and one tone knob, but the key is the three "three-position phase switches." These allow you to switch the phase of each pickup and turn it off, resulting in a total of 13 different combinations. While it doesn't have bi-sound functionality, it offers a wide variety of sounds. The tone pot has been replaced.
