Nice touch on a custom instrument but once you install them there's no way back!
Installed a set of these straploks on a customer bass, for the first time. I like the fact they're virtually invisible once the strap is off but they require some pretty big hole in the horn of the instrument... if you put them on a thick finish body you're probably going to need some very good forstner drill bit to avoid tearing. You'll also need a caliper to make the hole as deep as requested and not more! I wouldn't leave an unexperienced player install these straploks on a decent instrument for sure. The finish is good, though, and if you're sure you can live with straploks for your whole life, they can be a good choice.
I recently replaced the original Dunlop Straploks on my old Warwick Thumb (early 90s) as they were factory fitted and finally starting to look a little worse for wear. The replacements were easy to fit and are totally secure - I have no worries about them coming loose at a gig. They look good, yet subtle, and it's difficult to accidentally undo them. Definitely worth getting, although if you don't have them already fitted like I did, I suggest to take them to a reputable repair guy to have them fitted professionally.
