Because Fender is probably never going to make one of these what do you think it would take to make one for myself. I would probably start with a different P-bass and mod it but what mods would I need to make?
James Jamerson played a 62 p-bass. His signature bass would probably just be the Fender American Vintage '62 Precision Bass strung with La Bella 52 - 110 flatwounds.
And never change those strings. Ever.
