Grover’s Locking Vintage Deluxe Guitar Tuning Keys

Grover Musical Products has introduced the Locking Vintage Deluxe (533 Series) of guitar tuning keys. The 533 Locking Vintage Deluxe series is mechanically engineered to the most precise standards of excellence, with a classic look and styling. Grover’s Vintage Deluxe guitar tuning keys now come with a “thumb screw” mechanism which locks the string into place. Insert the string through the post hole, wrap around once, then lock by tightening with the thumb screw. Worm and gear are cut to mesh perfectly, thereby eliminating any backlash and slippage. The housings are self-lubricated for a lifetime of trouble-free service.
