Hi all. I'm a newbie to playing bass, and was looking for some resources as to parts and terminology. I want to find out about what makes a bass good, how to maintain it, what the parts of the bass are, etc. I play a Fender Jazz that I got for around 75USD used ( granted, with a couple paint chips), but it came with a screw missing in the bridge (again, not sure if that's what it's called). I was wondering where could get replacements. I'm not sure if this screw missing is harming my bass in anyway. Also, there seems to be a buzzing any time i hit the 9th-12th fret on the G string, and if i can get rid of it. Any help would be greatly appreciated.
