Independent shopping perspective

The Korena take

Grover’s nickel mid-size 305 Series tuners combine a compact 6-in-line format with 18:1 gearing for accurate, controlled tuning changes. They are intended for smaller headstocks, while the sealed, lubricated gear assembly is designed to prevent slipping and remain in service over time. The 22.4 mm posts accommodate most string gauges, giving players a practical route to fine adjustment within the stated straight-line configuration.
