Here's a strap scenario for you guys. Since I like my guitars to all have strap buttons and all my straps to have strap locks to go with each. Somewhere in the years gone by, there have been both topics about preferred straps, preferred strap locks, and even our favorite picks and strings. I have always owned both Gibsons and Fender guitars and now I've added a PRS, Washburn and now a Jackson. Well, here is what I decided a couple years ago since I knew that most Fender guitars came with a strap button that automatically fit the Schaller type strap locks. So, for my 2 Strats, Tele, and 2 P basses, I bought a strap for each, and installed Schaller Strap locks on them.
Then, for my Gibsons, I bought a dedicated strap for each of them and outfitted the guitars and straps with Dunlop Strap locks. This way, if for some reason, I was out and playing a gig and somehow my strap for a particular Gib or Fender guitar was missing from the case, I could always go to any of my other Gib cases I brought along as backup guitar and know that strap would work on the Gib without it's strap, and likewise the Fenders.
As for my newest guitars that I do not have Strap locks on so far, I have a couple straps that just have the standard holes that can slip onto any type strap button such as what is on my Jackson, Washburn, ES 135, and PRS. One such Strap is one of those super thick leather ones where the holes are not only stiff, but also thick to fit onto the strap buttons. I primarily use this strap for my ES 135 which I generally play seated. If the strap pops off, the guitar will not get damaged. My other lockless strap goes on my Acoustic, my PRS, and Smitty's old strap came with and goes with his Washburn I got from him. Sometimes I use the Grolsch rubber washers on these straps. They do the job.
