Uhhhhh, dude, you knew what he was talking about...
If I knew what he was talking about, then I wouldn't have posted a comment.
Straplocks aren't advisable if you've got a high end guitar the value of which you're trying to preserve. Too many people end up stripping the strap button holes badly. If it's a MIM or MIJ Strat then, yeah, get some straplocks.
That logic makes no sense whatsoever. If you have a high end guitar, more times than not, you are going to make sure the guitar has the lowest chance of falling off while you're playing it, hence the need for a dependable set of straplocks. Ususally, most people who own a high-end guitar will have some common knowledge of how to work on a guitar, which would include installing a set of straplocks. The rest of those folks who feel unsure about doing such upgrade, usually will take their guitars to a tech and will pay money to have them installed.
As far as the value of a high-end guitar is concerned, it's not going to be affected unless we're talking about a vintage instrument (example, a 1950's dead mint Strat) or a highly collectible like one of the $25K "Blackie" clones.
Would I install a set of straplocks on a Zakk Wylde model or on a PRS Dragon? Absolutely.
FYI, most American made Strats come equipped with Schaller straplocks. Most MIM or MIJ Strats or Squiers do not have straplocks and only have the vintage strap buttons. The high end Ovation guitars come with Dunlop straplocks preintstalled from the factory. Before you make some ridiculous statement like that, I'd suggest you really think about what you're saying because it made absolutely no sense.
