Whats the Difference between Fender Affinity Series J Bass and the Fender Affinity Series P Bass?

Im looking for my first bass and i was thinking between these two. I will mostly play classic rock and hardcore rock.

Also any other suggestions for a bass would be nice.
Thanks

Well to start off...ones a jazz bass and ones a P-bass...they have different pickups and usually different neck shapes...but the low end squires probably have the same neck.

P-basses are a little more boingy and round in tone while a jazz bass has alot of attack and better highs...if yer looking to play hardcore i would definately go for a jazz bass.

Also DO NOT use ernie ball strings on it....just trust me on this one...
