I'm not sure if this would be the place for this question, but... Does anyone know of a good leather strap that goes over both shoulders? I'm really partial to these for the weight relief they provide as well as the ability to balance my basses fairly neutrally. The thing is, the ones I have & all I can find are kinda cheesy nylon web material. So does anyone know of a nice one or am I gonna have to get them custom made?
