Alright, so I'm a beginner picking up a bass to start playing in my school jazz band. I have an amp and bass picked out, and I'd like to see what you guys think of my choices. (The amp wouldn't be used in concerts, the school would provide them. They'd be practice only for now.) The bass is a Yamaha RBX170. The amp is a Ampegg BA108 25 Watt. Also, should I consider getting new strings or would the vanilla ones work fine?
