This is a large shaft fine tuner for the Kahler 2760 Steeler or the 2720 Spyder.
The 2720 Spyder had two fine tuner possibilities, either the 8377 small shaft used in the early years (before 1988), or this 8477 fine tuner with a larger threaded shaft (after 1988 mostly). So if you have a Spyder, please check to be sure if the threaded shaft you need is the smaller 1/8" (3.4mm) shaft or this larger 3/16" (4.6mm) shaft.
These do not fit Floyd Rose tremolos, those use the 9255 fine tuners.
