Grover102SV Roto SB Guitar Tuning Machines Gold
Independent shopping perspective
The Korena take
Finished in gold, the Grover 102SV Roto SB tuning-machine set uses transparent caps to show the gears underneath. Its sealed gear system contains special oil, and the 18:1 ratio gives room for incremental tuning corrections. A tension screw changes the effort required to turn each key. Check your headstock before installation: these are intended for 25/64-inch post holes and strings up to .074 inch. Installation hardware is included.
