I headed down to the local guitar place the other day and played a few jazz basses, as I'm considering purchasing one soon. I played a number of them, of different types. The first one I played sounded awesome. It was an MIM standard, nothing special. Perfect tone, exactly what I want. I noticed the pickups had the "staggered pole pieces" jutting out. Then I played a few others, including a Geddy Lee and several MIA jazzes. The MIA jazzes did not have staggered pole pieces. I thought they sounded considerably worse than that first MIM I played. They seemed to have new strings and all. The Geddy obviously had old strings, they felt dead. But I've played that one many times (they can't seem to sell it) and it sounded good before. It has the staggered pole pieces. So are these staggered pickups a different kind? Is there a reason they sounded better (punchier, more defined but still with a fat bottom end).
