got it for an acoustic guitar, with only one strap pin on the bottom and reverse-fixed it on. surprisingly, it fits very well.
the belt with the holes goes on the bottom and on the other side, the small piece of leather passes 4 times around the head, under the strings, and ties it nicely. lastly, i switched the pad on the other piece of belt and used something long, sharp and slim to drill new holes.
build-quality is there, i encourage you to get creative with it.
