He's a little high-strung your husband, eh Bean :-)
High strung!? I think not. I'm a bassist, so i'm actually between B three octaves below middle C, and E(41Hz), A, D, G. Don't go NEAR the G-string!! It might pop! But only if i'm feeling funky.

As for the question that Bean posed, I believe that the strap for a guitar attaches to what is called a button.
