I'm not married to that J pickup; I really want the P split coil sound and what's at the bridge is probably optional, though I am very fond of my two jazz basses and am quite happy to dig gnarly tone out of the bridge pickup when it suits me. I just sold a MusicMan Caprice which is a P/J with humbuckers because I couldn't get what I wanted from them. The niche for this new bass will primarily be Country/New Country style cover material, which is why I want 5 strings with a P pickup. The rest is negotiable as far as I'm concerned.
I agree with you on this, I love jazz basses for what they are and play them accordingly, much like I love basses with humbucker pickups but when I have that hankering to use a PJ bass, to me it should first and foremost sound like a P bass with that single coil as an extra option for versatility. I often have the single coil on just a tad for this reason or sometimes don't even use it at all- so a bridge humbucker on a PJ seems a little bit of overkill imo.
Sire doesn't make a P bass, but their PJ isn't a bad option at all - the important thing with the Sire is the versatility and quality the heritage preamp has to offer on top of an already good quality bass. For the money, it's definitely one of the best options out there.
