I don't know if I should change my strings or not!! My band hasn't played a show for a while now and I've recently acquired a Carvin LB75 strung with XL-170's and I absolutely love it. I don't know how old the strings are but they don't seem that bad at all. I bought a new pack of the same strings that it is strung with but I'm worried that if I string it up, the bass won't play as good as it does right now (it might change the tension on the neck or just feel different). I know they're the same strings and all but what do you guys think? Wait til after the show to put on fresh strings or string it up now and rock the new strings this friday?
