Schaller's Strap Locks are unique mounts for your guitar that will help to keep your strap in place and prevent it from falling off. Any guitar player will know that sometimes your strap will fall off, potentially causing damage to your instrument! Of course this is unwanted, especially if you're playing shows, as a regular strap would have a greater change of falling off on stage since you're probably moving a bit more. Even if you aren't playing out, it's definitely a good thing to have your strap securely in place without having to worry about it falling. That's where these Strap Locks come into play, as these are pretty much your best bet for never having to worry about your strap falling again. You screw these right into your guitar where your stock strap attachments would be and your strap attaches securely onto it without any doubt that it might be falling off. The strap goes in between two parts of the lock, so it's definitely not going anywhere once you've got it in place. This is a really inexpensive way to keep care of your guitar, again, especially if you're playing shows a lot. Some guitars have better built in strap attachments than others, and you know your instrument best to know if you would need something like this. If you do think you need a stronger and more secure connection between your strap and your guitar, the Schaller Strap Locks are the way to go. There's very little money necessary to get these, as they are very inexpensive, so if you have the slightest need I'd recommend picking up a pair as it's worth spending a very small amount now than spending a lot later if your guitar were to fall off the strap and break into a million pieces. It's even worth it to prevent minor scratches and bruises from potential falls...
