In this guitar tutorial, learn this great tip on how to make your own strap lock system for musical instruments. No modifications are required to the original buttons or button holes. They can be easily removed and replaced if necessary. They are sometimes called "lock-picks." Of course, these don't have to be made from a pick (although the nylon material is highly recommend), but guitarists don't go to the hardware store for parts. Make a strap lock for your guitar and play guitar with ease!
