Hi there. I am going to check out a 2006 MIM Fender Jazz bass on Saturday. I am totally new to basses but have been playing guitar for a number of years. What things should I look for when evaluating a bass. Are there any definite "walk away" signs. Guy says it's barely used and in like new condition. What's a fair price for a 2006 MIM. I offered $300, he said he would couldn't let it go for less than $350 (Canadian). Thanks.
