Hello, I am a guy, (from the poor ones) that is definitely not a professional... I got a beautiful student bow but it seemed a bit heavy compared to my previous very cheap student bow. So I carefully sanded it and about the feeling and the weight my experiment went very well... I mean its a perfect not varnished bow but I have wasted the part with silver threads and rubber grip. So my big question is.... : Is there any way to replace them? You know with some decent way!! I have to walk the life for several years with it... meaning playing with it!! PS: I have a lovely friend witch is a traditional instrument luthier(Huge support) but I really cannot bother him being uninformed... he barely have the time and patient to speak with me... :-D And I am miles away from "dedicated bass luthiers" not just miles but many basses in money value... I am trying to do an other thread about this stuff. But for now... Can anybody help/inform me???? Thank you!!!
