I've got a mid 80s Japanese Fender Jazz Bass specail. It was my first bass and I still play it. The other day someone noticed the serial Number was 0001946. He said it was more valuable with a low serial number. I'm not looking to sell it and I've kept it in great shape but I am curious. Do serial numbers add/take away value?? That's a new one on me. Any info would be helpful. thanks.
