Are the pickups in your 2012 P bass the Fender Custom Shop pickups that they are now using for the American standards.
I had the same question prior to purchasing the bass and contacted Fender customer support. They responded that the pick-ups in this 2012 model were NOT the custom shop pups but the same pups used in the post 2008-9 updated MIA P basses.
Here's a TB link where I quoted the response I got from Fender Customer Service: http://www.talkbass.com/forum/f8/fender-fsr-p-basses-867242/
Honestly, these pups sound darn good. I've heard that the newer pups have a more vintage sound and these a more "modern" sound. I haven't played a 2012 P bass with the custom shop pups so I can't provide any personal insight.
I figured, if the pups were an issue for me I would replace them with a set of the custom shop pups (about $65.00 new). So far, I have no desire to do so.
Hope this helps.
