I'm not sure you'd want to use this for a guitar, it really is a thick padded strap, but it fits a bass pretty well.
My only gripe is with the length. There are three holes for the adjustment, so you have three positions where you can set it and that's it, you don't have the sliding adjustment like on many other straps. This is probably due to the thickness of the material.
But even at the longest length I find it a bit short. It's ok for a bass, but even that I normally have lower, and I'm 1.89m tall, so hardly a giant.
Compared to the Taylor guitar strap I used before, it's a lot more comfortable, but a lot less adjustable.
Also the brown is a lot lighter than what you see on the picture here.
