Has anyone tried the D'Addario auto lock guitar strap on a PRS with our pancake sized strap buttons? I've been searching for the best strap to secure my McCarty 594 and not having much luck so far. I tried 2 PRS straps and neither felt very secure, with the ends not fitting entirely under the strap button once over it. The best so far has been a Mono Betty strap, but even that is starting to fray at the button hole so it doesn't sit cleanly under the pin anymore. These auto lock straps seem like they would be perfect if they can fit over the larger PRS strap buttons. FYI... I don't want to remove the stock strap buttons to replace with any other brand of locking strap buttons. Silly as it may sound, this guitar is "perfect" to me, and I really want to keep it completely stock.
