Does anyone have a date range for Fender Jazz bodies that have a medallion on the back that says “Original fender body”? I just bought a parts bass that the seller said had a MIM body but it’s older that that. It’s had a few mods in the electric cavity to fit active EMG’s and I cant find any date there or under the neck but who knows what has happen to this poor bass in its lifetime. The date won’t change the fact I’m going to play the heck out if it. I’m just curious
