Im in the market for a bass and there one thing that has always been a problem for me. I have a slap style where it requires a good hunk of room between the neck and the neck pup. When i try slapping on basses with j pickups i usually dont have enough room, its gets too crowded. Anyways im in the market for a higher end 5 string and theres a certain bass i want that has j bass pickups, but for an extra charge i can get a MM style pickup giving me the room i need. What are the pros and cons of the j style in general vs. the mm style pickups?
