Genuine Fender Stealth Bass String Retainer will help eliminate string buzz on your bass guitar. 

This chrome-plated retainer increases the break angle from the tuning key to the nut, providing greater tension, a more secure fit and greater stability. 

The retainer also replaces the washer on the tuning machine for your B, E or A string, alleviating the need for additional mounting hardware. Used on most American Deluxe and Dimension bass guitars. Fits most vintage and modern four-and five-string Fender basses.
