I have a USA P Bass and a MIM Deluxe J bass and they are both good instruments. Of the two the P Bass weighs less and is easier on the back and shoulders. The deluxe J has it's input jack on the bottom edge where the majority of basses I have seen have theirs. The P and other standard J basses all have the input on the front of the body.
This brings up a question. Why do Fender and other P and J bass type clones have the input jack on the top of the body instead of the side of the bass? Is there an advantage to having the jack on the front or is it to preserve the look of the originals?
To get back to the question of this link, yes I think that the P Bass is among the better basses out there. The look, sound, feel and overall vibe of the beast has a lot of history behind it. It's a keeper.
