I'm not very happy with my tone, and, being a bad viola player, I naturally blame my tools rather than myself. I'd quite like to try a different rosin - maybe that green one that rosfrog mentioned (Jade, I think). But I'm not sure how to go about this. As I understand it, before changing to a different rosin you have to get all of the old stuff off the bow. And that, it seems, is quite a performance - there was a thread about it a few weeks ago. It might almost be worth getting a new bow rather than go through all that (bearing in mind that my bow didn't cost much).
But this makes me wonder about how buying a bow works. I know you are supposed to go and try several in the shop. (I couldn't do this last time because I barely knew which end of the bow was which.) But you can't try a bow without putting rosin on it, and you only buy one of the bows you try; so all the others will be gunked up with rosin before someone else buys them. What if the someone else wants to use some other rosin? How does that work?
