The Korena take

Configured 3+3 and finished in nickel, these Grover 505 Series Mid-Size Roto-Grip tuners bring a locking system to a compact format. The 18:1 gearing is intended for smooth adjustment and precise tuning stability. Their slightly larger housing accommodates the Roto-Grip mechanism, which holds strings securely for improved tuning retention. They are positioned for upgrades or new builds where a lightweight, sturdy tuner set and a direct replacement for non-locking Grover MINI 205 machines are needed.
