So I recently purchased a new Yamaha AC3R acoustic-electric guitar.

Great guitar, except for the strap peg. The strap on the guitar doesn't work with this strap: https://www.sweetwater.com/store/detail/50BAL02--daddario-auto-lock-padded-guitar-strap-diamonds

So my question is:

1) Do you recommend a locking strap for my $1000 guitar. The strap doesn't look like it is about to fall off, but I know that some people like to buy a locking strap.

2) If so, what would you recommend? Would something like this work?

If anyone has an AC3R or some other Yamaha A-series guitar, that would be great!
