The Korena take
Vintage-styled nickel tuning machines with a 6-in-line layout and a locking thumbscrew system. The 15:1 ratio is intended to give you precise adjustment when bringing strings to pitch, while sealed, lubricated gearing supports stable operation. Lock each string at the tuner, then use the controls for fine tuning. They are presented as a drop-in replacement for many instruments, and the supplied bushings and screws support the installation.
