Item No.: #5A050 This is a removed part from a Yamaha SG-700 manufactured around 1976-1979. Considering the business aspect, the parts should have been standardized as much as possible, so it is thought to be a common part with other models. Based on my confirmation using catalogs, etc., it seems to be common with the following models manufactured around the same time. (In addition, there is a possibility that it was also installed and used in other models manufactured around the same time.) SG500/SG700/SG800S * It seems that there were almost no other models that adopted this chrome-plated type with Grover-like (half-moon) knobs. This is a single item (individual, loose) for sale as shown in the photo. It has been cleaned and polished with polishing agents before listing, but the dirt etc. has not been completely removed.
