He must have mixed them up. Wilkinson was first, all his personal guitars have Wilkinsons (and all the early JB Sigs had them), Wilkinson stopped making their version, and Fender's LSR has been in continuous production ever since Fender started making their own version to replace the Wilkinson. Did he buy all of the Wilkinsons Fender had on hand when Fender made the switch? Maybe, sure it's possible. I don't know if people like Clapton, Beck, Johnson actually have to buy anything from Fender. I've always assumed that their endorsements make so much money for Fender that they get stuff free. Pretty sure that if Jeff had just asked them to reserve the rest of their Wilkinsons for him, they'd have been glad to save them for him for free. But maybe stars actually pay for stuff so they can write them off on taxes. Or maybe he loves them so much he bought the Wilkinsons just to make sure changes in management couldn't jeopardize his stash.
