Independent shopping perspective
The Korena take
Built in a 3+3 layout with keystone buttons, Grover’s nickel Vintage Deluxe 133 Series tuners use a 15:1 ratio and a closely meshed worm-and-gear design intended to prevent backlash and slippage. Their self-lubricating housings keep the mechanism lubricated. With supplied bushings and screws, they are positioned as a direct replacement for Grover 505FV and 533 Series tuners; the posts accommodate string gauges through .074 inch.
Strong match
Who this is for
- Replacing Grover 505FV or 533 Series tuners using the supplied bushings and screws.
- Guitars using string gauges up to .074 inch and a 3+3 tuner arrangement.
Consider the trade-offs
When to look elsewhere
