This is metal hardware from a Fender Custom Shop Stratocaster Heavy Aged. It's not necessarily special just because it's Custom Shop; it's likely aged USA parts. It's probably the same as those found on the American Vintage series. Would you like to add some visual flair or upgrade a Mexican-made guitar? (Compatibility with Japanese-made guitars is unlikely) The tuning machines are stored in a GOTOH box for safekeeping. I'm also open to selling individual parts, so feel free to comment with any questions. ※This is a left-handed product. Please be aware.
