I don't have great shoulders, but my low bar hold doesn't mess with it. I put my hands all the way out, on the wide part of the bar between the bar and the weights, then raise my elbows so they are pointing behind me. That creates a valley between my traps and my rear delts in which the bar sits perfectly. When I go heavy I can push it back a little more and sit the bar across my rear delts. It doesn't hurt my shoulders, but it's not the most comfortable thing either.
It's the wide hands that takes the pressure off the shoulders.
