I recently purchased a black bowhair from my local music store, in Belgrade, Serbia. The maker is Gewa. First thing was, the price was really affordable, 12-13 euros, so I bought 2 packs. When I brought it to my luthier, he said that the hair was surprisingly thin for bass bow hair. And, maybe I am now influenced by his words, but the overall grip I get is now less then I had with previous hair, wich was well used. I am by no means a virtuoso player, and I mostly play folk music, but I cannot escape that feeling every time I play. I have searched the Thomman, but they sell only white hair, so were could I get black bow hair, preferably from seller in Europe? I know there are some, but I cant find them, or, should I go for almighty Aliexpres?
