Independent shopping perspective
The Korena take
Gold Roto-Grip Locking Vintage 533 Series tuners with Keystone buttons give a 3+3 headstock configuration a vintage-styled update. Sealed, lubricated gears and a 15:1 ratio provide controlled tuning adjustment. Each tuner uses a thumbscrew to lock the string in place, a feature intended to prevent slippage during energetic performances. They are made as a drop-in replacement and are described as retrofitting many popular tuner models.
