Re: Jazz (neck) sound similar to a PAF?
Jazz is definitely not a single coil sound. In fact compared to the '59 (sorry I dont have a real PAF to compare) the Jazz sounds louder - will overdrive my Fender-style amp with a full chord where the '59 won't. That's due to the stronger low bass in the Jazz...the PAF sound is a bit rolled off int he low bass & often a bit loose there too, and sounds to me like it has more mids than a jazz. The Jazz sounds like a cleaner, flatter '59 with a bigger, tighter bass. Example, palm muted power chords with the 59 neck sounds pretty good, but the Jazz is gonna get someone's attention!
It is not sterile sounding: it is a sweet sounding pickup. It has some upper register sweetness, and I really like the lack of any muddiness at all. Split (in the neck) it has a cool woody tone that really works, sounds kinda acousticy. I don't find that my '59 neck sounds very useful split.
All in all I think you need a guitar that has both - the '59 (or pearly gates) neck for that dirty grindy blues stuff, and a Jazz for clean cleans and really powerful, un-muddy rock tones when used with overdrive.
