Prevent string buzz on your bass guitar with a genuine, easy-to-install Fender Stealth Bass String Retainer. 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. • MFSKU 0078972049 • UPC 885978542826
