I've been using the old Red/Black combo for a while, and these are a nice new colorway to retrofit on the guitars that don't have them yet! It would be cool to get them in all the classic Fender colors to match our Strats and Teles in those colors.

I put them on a strat today and it fits great. The strap Im using has slim ends so when you put the locks on it doesn't get bulky to the point it doesn't fit. On the other end, I tried it on a Ernie Ball guitar with thicker strap ends and it didn't go well. It just didn't fit and would literally pop off if I tried to hang the guitar on my shoulder. Just be aware of the strap you're using, it might not even need one

Don`t risk your guitar becoming detached from the strap (rare event but sooner or later it does happen to everyone !). A simple fix if you do not want to install a locking device by replacing the strap mounts. Why risk your expensive (and heavy) Les Paul when for a couple of $ you can easily add the rubberized safety washers. (Don`t forget to periodically check the strap hole in case of long-term wear as this can release the guitar into a ninja reflex attempt to avoid the influence of gravity regardless of whatever locking system you have in place)
