The 503


In 1986 and 1987 Yamaha launched 3 503 models, the 503J, the 503P and the 503R. Information and photographs are difficult to get. None of these were produced for very long and seem to have been domestic only 2 of them appearing in Japanese catalogues, and the other in no catalogue I can find. If they were domestic only they are likely to have been made in Japan. They seem to be very rare in the western market. All were released at 55,000 yen despite the J seeming to be higher spec. As far as I can tell there is no difference between the P and the R except for the headstock and different neck materials. If anyone does know of any other differences please let me know. One might believe that the R replaced the P but they both appear in the same catalogue.
