Dunlops have never failed me (even today, when practicing strap spins).
I can say the same thing: in 20 years of playing and 18 basses I've
never had either a "disengagement" or screw problems using Dunlop Strap-Loks. Then again, I believe it's a "1/2 dozen or the other" situation - I believe Schaller locks are just as safe, there are simply a few things that I personally don't like with their design. They have much more mass hanging off the end of the strap which can put a decent-sized "ding" in a bass' finish, and in my usage I find that they take a touch more "work" to disengage and can't be done with one hand like Dunlops.
Pretty much every method listed here so far is a workable solution. The Ernie Balls are nice, but as someone pointed out fairly big (and as much as Sterling Ball hyped them pre-release, I don't find them super-innovative as he had let on). The only system I've
not liked is
Dunlop's "ClipLock" system where you replace the buttons with their small amount of strap with the female end of a "industrial" clip which clips onto the male end on the strap when you're ready to use - the biggest problem is you're stuck using *their* strap and have no choice which tends to be
very slippery and is hell if you've got any type of neck-dive issues, which for us bassists and our liking of
wide straps and materials such a Leather or Neoprene is a no-go as far as I'm concerned.
...It's also good to know that I'm only a Grolsch away from a workable lock!
