Designed to work with practically any guitar with strap buttons, the D'Addario Planet Waves Auto Lock Guitar Strap ensures your guitar won't come loose during a gig. If your strap has never worked itself off your guitar before, consider yourself lucky. If it has, you'll probably do just about anything to make sure it never happens again. The Auto Lock Guitar Strap features spring-loaded clamps that grab your strap pins tight. And the soft nylon construction feels great to wear.
