Independent shopping perspective
The Korena take
The nickel Mid-Size 505 set brings Grover’s Roto-Grip string-locking design to an 18:1 tuner ratio. Its compact format is intended for inline layouts, 12-string guitars, and smaller headstocks, while the slightly larger housing makes room for the locking mechanism. Strings are held securely in place for improved tuning retention. If you are moving from non-locking Grover MINI 205 tuners, these are made to drop in directly, keeping the upgrade straightforward.
Strong match
Who this is for
