You can finally let go! Music Nomad's patent pending Acousti-Lok is a strap lock adapter that adds the safety & flexibility of using strap locks to your acoustic guitar without permanently modifying it. Designed to be used with SCHALLER style strap locks (not included), Acousti-Lok's strong solid brass construction gives you the security you have been looking for. With different Acousti-Lok designs to choose from, make sure you find the one that is compatible with your acoustic guitar output jack. Acousti-Lok was not designed to be used on recessed or flush mount jacks.
Simply remove the jack end cap by turning counter-clockwise and replace it with the Acousti-Lok strap lock adapter. Spin clockwise until the Acousti-Lok is snug tight!
