Differences in Fender American Jazz basses

Hey folks. I am hoping that some of the Fender specialists can read and respond to this. I have 2 basses that are available for me to purchase this week, and I am stumped. They are a '97 Fender American Standard Jazz Bass and a '04 Fender American Jazz Bass. I tried looking up the info through Fender's website, but didn't see too much regarding the details. Does anyone know which would be the better purchase? Was there a difference in production during those years? Is there a difference between American Standard and American?

 

Well, I called Fender & spoke to someone in customer support. He informed me that the biggest (and possibly only) difference between the '97 American Standard and the '04 American is that the '04 has the S-1 feature on the Volume 1 pot. So, now my question is, what is the preference regarding the S-1 switch?

 

I went with the '97! Looks and plays great! I had a friend do a set up for me. When he took off the pick guard it looked like someone spilled cola on it as it was caked underneath. Other than that, it's a great bass. This pic is from before the clean up.
