Description
Grover’s 502 Series brings the trusted Rotomatics® 18:1 gear ratio into a locking design, so you can restring quickly without fumbling with multiple wraps. Just feed the string through the post hole, take one turn around it, then snug the thumbscrew to lock everything in place. The result is quicker string changes, less slippage, and steadier tuning stability during play.
- 18:1 Rotomatics® gear ratio for precise, smooth tuning
- Thumbscrew locking mechanism secures the string with a single wrap
- Black chrome finish
- Set of 6: 3 treble side, 3 bass side
- Designed as a drop-in replacement for most standard guitar machine heads
- All mounting hardware included
Because they’re built to standard dimensions, these tuners install on most guitars currently fitted with conventional machine heads, making them an easy upgrade for players who want locking convenience without modifying their instrument. Whether you’re outfitting a build or swapping out worn tuners, the 502 Series pairs classic Grover reliability with the added speed and security of a locking post.
