D'Addario DGS15 Acoustic Quick Release System

The patented Quick-Release System converts your favorite strap into a quick-release strap and is one of the most popular, must-have acoustic guitar accessories available.

Just look one end around the headstock, loop the other end of the buckle through the end of your strap and clip together.  Takes seconds to set up and no need to drill a second strap button to your guitar.

It won't come loose during play, and the extra length of the cord keeps the guitar strap from interfering with your and when playing near the headstock.
