I am relatively new to the electric bass (and it is my first instrument), and while I was browsing through a catalouge I ran into some terms I was unsure of the meaning off. My first question is what is the difference between a Precision bass and a Jazz bass? I noticed that there are many types of pickups a guitar can have, descriptions of them or links to descriptions would be appreciated geatly. What's the best kind of bass/pickup for playing alternative rock (stuff like Nirvana, Oasis, Bush, etc)? That's all of the questions I have for now. Thank you for your time.
