Some like the body difference, some like the electronics difference, some like the difference in the necks. To tell you the truth, I could not care less. I have P's and I have J's. I play them both equally, I like them both equally. To me the tone can be adjusted so there is very little noticable difference. After five minutes of playing I don't feel any difference in the necks. I don't think there is any great movement to one or the other. Or..... I guess after 45 years of playing Fenders, I am just numb to the differences. I just love to play bass.
