Quick Release, PlanetWaves
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.
The Quick Release System takes seconds to set up: just loop one end of the quick release buckle under your strings around the headstock. Loop the other end of the buckle through the end of your strap. Just squeeze the quick-release and you're free: no knots to struggle with and no need to drill a second strap button into your guitar. It won't come loose during play, and the extra length of the cord keeps the guitar strap from interfering with your hand when playing near the headstock.
