I bought a 2008 Am Std P bass from a TBer that came with Nordy MP4's. No complaints at all with them, they sound awesome. I just bought pups from a 2012 Am Std, so CS pups. Would you keep the Nordys or swap to the CS pups? I know just enough about pups to get in trouble, I do know that I like all stock Fender basses though. NP4's or 2012 CS?
