Beautiful Jazz basses guys! I have a '75 lefty Jazz bass that is great, I know I got lucky, as it is a 3 bolt but the neck pocket is solid and has never moved. The best part of my bass is the near one piece flame swamp ash body. Yup, a mid 70's Fender with the most beautiful (almost) one piece body (the second body piece is 1 by the controls), very light weight because of the swamp ash. It sounds and feels terrific. I also have a '74 P bass that is excellent, no issues, plays fantastic. I guess I got lucky on my mid 70's Fenders. I agree with Rami, it is hit or miss on any old Fender, they are assembly line products and not always consistent. Age does not mean quality...but when you find a good one, grab it!
