D'Addario is good and long lasting. Also, because each set of strings are packed in plastic package, you can buy 3 sets at the same time and they are still fresh after a few months. That way you save money. (Sorry i can't type chinese...)
我是覺得你要看你的琴本身是樣的聲音,再去選你要的弦,像我的是Ibanez的RG-320(新的那一版琴),以它本身的聲音來說,我是選擇Blue Steel的弦(9-46),因為我本身也是玩metal的,如果你覺得琴的聲音不夠凶的話,那你還可以換一組Pick-Up.......
