The Korena take

Nickel six-in-line locking tuning machines in Grover's mid-size Roto-Grip Rotomatic format. Their 18:1 gearing is made for smooth, precise tuning adjustment, and the locking system holds strings in place to improve tuning retention. The compact set is intended for inline applications, 12-string guitars, and smaller headstocks. They directly replace non-locking Grover MINI 205 tuners, though the locking design uses a slightly larger housing.
