This is a small shaft fine tuner for the Kahler 2710 Killer (2700 Series) or the 2720 Spyder.
The 2720 Spyder had two fine tuner possibilities, either this 8377 used in the early years (before 1988), or the 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 this smaller 1/8" (3.4mm) shaft or the larger 3/16" (4.6mm) shaft.
These do not fit Floyd Rose tremolos those use the 9255 fine tuners.
