My bass is about 25+ years old, and hasn't been used until about a year ago. I didn't replace anything when I got it (a year ago). I was adjusting the bridge (my 1st time adjusting a bridge), (it was turning up), by tapping it with a hammer, the way I've been shown, and it cracked. The crack is from the E string towards the G, it's about 2-3 cm, very thin, like a hair. Should I leave it the way it is, or should I take it to a luthier? I'm not going to see my teacher for 2 weeks (going away). I'm not going to play it until I know I'm not going to break anything, or I get it checked over. Thanks alot.
