I just put a PU in my main P bass (split coil) that has one pole piece per string- I may never play anything else. 
Nope. I wrote to him when there was a protracted discussion (probably on The Bottom Line, maybe here on TB) about ,"I Want You Back" with many saying it had to be a pick. The response was "No, never a pick, always finger"
The single coil pickup has a critical difference compared to a Jazz or split-coil Precision, the single magnet pole per string. That gives it a very different attack.
