I have used Dunlop Straploks exclusively since the early '80s and make sure that every new guitar I own has Dunlop Straploks installed as soon as I feel it's a keeper. The nice thing about having them on all your guitars and straps beside the obvious safety and security that your baby doesn't slip loose from the strap is that once installed on all guitars and straps you are free to swap straps to your liking.
Tip: When installing these on thick leather of suede straps (such as the quality straps from Levy's) you can carefully use a flat head screw driver under your thumb during installation to work the button into the thick strap ends. Once you have patiently worked the button into the strap hole working in circles until the lip of the Straplok is accessible to install the lock-washer then you are done. "Patience weed-hopper" In the end you will have a safe and secure guitar for years to come. I have purchased over 20 of these over the years and would only trust these as they have yet to let me down.
Highly recommended! Make sure your next guitar is "Sweetwater selected", "Dunlop Straplok protected",
Tell Mike Picotte at Sweetwater that Johnny B sent you!
