Ready for your next guitar project is a set of black finished SGM guitar tuner bushings. These bushings are to be used on vintage guitar tuners that will be installed in 10mm peg holes. Vintage tuners commonly had skinnier posts and used 8mm bushings which do not fit in most modern holes. Also very helpful for vintage instruments that have had the holes reamed from years of use or modifications. The conversion bushing fits right on your tuner post, and pushes snugly into the peg hole. They fit a tuner shaft up to 5.9mm or .23″. See our listings for bushings in nickel as well as gold finish.
