I play my guitar with neck high up to my shoulder, the next is almost perpendicular to the ground. As much as I'd like to play like Slash with my guitar slung down at my ankles I just can't do it. But the guitar always want to rotate to neck down. I have a cheap strap so wondering is there a better non-slip one that gets better traction on my should and clothing? Or is there a guitar harness that keeps the guitar firmly in position and maybe distributes weight more evenly around your torso?
