Very popular choice of strings for violinists around the globe, used for solo, chamber and orchestral work as well. Can be used even on electric violins. These are like "industry standard" where I live, almost every other violinist have them and love them on their violin. Pirazzi's features intensive powerful sound rich with overtones, good dynamics, easy playability and excellent response - all good things you'd expect from today's modern string.
For those who can't decide between ol' "green" Pirazzi vs new Pirazzi Gold I would say go for Gold as they are definite upgrade, you should check them out and you definitely wont be disappointed. Just don't get me wrong, Pirazzi's are really great, but Pirazzi Gold's are even better.
