You know the black thing not the place you fasten it to your guitar but the adjusting one to make it bigger and smaller. Where is that gonna be on ur back or front side, im assuming your back right?
I put mine on the front, so closest to the head of the guitar.
whatever youre more comfortable with, sometimes i have it in the front, so i reach up to my shoulder to adjust it, other times, if i'm playing bass, i like it on the back, and i reach down lower, doesnt matter, it's what you're most comfortable with
Yeah, apparently it is "supposed" to be at the back.

That's probably true seeing as it is the case of leather straps etc.

Oh yeah, I forgot to mention: nice strap.
