This listing is for a set of six (6) Leo Fender era Music Man 6 string guitar tuning keys. These are the style that debuted with the Sabre guitar in 1978. They fit the earlier Sting Ray models, but have a butter bean style button rather than the Schaller rectangular style. One back is a misprint, stamped upside down! No, it isn't a lefty, it was simply stamped flipped over. In great condition with original bushings and screws. Sold as is.
