I need new strings even though mine are still pretty live. I need some advanced knowledge though. Thnx. Right now on my bass, I have a set of D'addrio's. (I think). I got these because I broke my friends strings before I bought it from him. He got a new spector and he has always used blue steel stings. He says these are better but I'm not sure. Are they? I like mine pretty kule now but could there be anything better about them aside from theyre $25 more than mine.
