The Korena take
Grover Roto-Grip Locking Vintage 533 Series tuning machines pair a vintage-style Keystone-button look with a thumb-screw string-locking mechanism. Lubricated, sealed gears and a 15:1 ratio provide smooth, precise tuning action, while the lock holds strings in place to prevent slippage during energetic playing. The chrome 3+3 set is positioned as a retrofit option for many popular tuner models, making it relevant when replacing tuners while keeping a vintage-styled appearance.
