Despite being quite large, I’ve seen failures with the PRS buttons...right CRGTR?My stint with Schaller started when my Lester came off the button for the 500th time, way before PRS. But my straps all have locks, so...
Never have had a problem with the PRS buttons. I use straps with leather that’s thick enough to stay in place snugly, so maybe that’s part of it.
I’ve seen guitars with Schaller locks fall, mainly when the mechanism on the strap becomes loose, which seems to happen if you don’t check them (Loctite may solve this).
I’m not a fan of metal strap locks, they’re rattly gizmos. With non-PRS guitars I’ve used Grolsch rubber O-rings over the strap button, but I haven’t owned anything but PRS in over a decade, so...
