swee lee has this addario strap - the black simple looking one..can go high(look, it's high on me and i'm short), doesnt come out w/o a strap-lok and it's very simple looking..
speaking of strap-lok though, the strap i mentioned has a strap-lok version..u cant remove the strap-lok, and it kinda scratches ur guitar near the strap pins cos of the poor design..i wanted to use it on my prs, but i changed to a proper strap-lok instead, simply too afraid.
