There are several artists on YouTube playng BSs, both ways facing, (wouldn't it be easier to play in D, E, and A point in?) one lass with two bows, and several on stands, including one guy whose stand is a species of harp which he uses for a Bass. There is one extra long one that looks to be approaching three octaves. Impressive.

Fortunately, bows are easy to make, as you can see by examining them.
