Independent shopping perspective
The Korena take
Vintage 533 Series Roto-Grip tuners pair a gold 3+3 layout with a locking thumbscrew system that holds each string in place. The sealed, lubricated 15:1 gearing gives you finer adjustment while tuning, and the self-lubricating housings remove an ongoing maintenance step. They are intended as a drop-in replacement for many instruments, with the required bushings and screws supplied for installation.
Strong match
Who this is for
- Replacing compatible 3+3 tuning machines while retaining a vintage-styled gold hardware look.
