I hardly doubt this. Would be interesting to ask a Fender Tec: what exactly was the difference between a '62 and a '63 JB Pickup?
Are you sure, they are discontinued? They are on the Flea Jazz (the Mexican copy of his old JB) and on the American Originals 60s Jazz. I own two AVS '64 Jazz and love them.
Good point. I know you can still get the '64s in those models, but I don't believe you can purchase separately anymore. I have them in my AVS '64 as well and have no desire to change, just curious as to how they compare. I'm no expert on JB history, but I don't recall any major changes, so it seems a bit odd to create a new line if the differences are minor. Maybe Alnico 2 vs 5?
