Want to find out if jazz bass ia a deluxe or standard model

That serial number doesn't seem to fit the standard formula. You should contact Fender directly. Here is the link-
Contact Fender Musical Instruments Corporation

Made in Mexico in 1999.

The best way is to contact Fender Customer Service. I find I get better info by phone than email, because if there is a question you can clear it up right then. Here's a link

I would need the complete serial #s, this serial # would be a 1968. Fender did not manufacture a Deluxe (or active) Bass guitar line at that time.

Check front of headstock, rear of headstock. Neckplate on the back of guitar. If not, remove neck and check the heel and neck "pocket."

# z2135395 Your Jazz was built at the Fender Corona, CA. USA Plant.
2002-2003

Try reversing the wires in your input jack. Please repost results. Thanks!

usually on the back of the headstock, sometimes on the neck plate where the screws hold on the neck

Serial number starting with M indicates a Mexi Fender, if thats what you mean. It is a real Fender, it is just made in a plant in Mexico for much cheaper, and sold for much cheaper. I've played some Mexican Fenders that played better than American, and generally they are all decent, but most of the time people would rather have the American versions.
