Well I am still trying to unlock the secrets of the Jazz bass. I sent the '62RI back for finish problems and am left with the '08 American standard. The Dimarzio didn't cut it in the band mix it sounded to grunty. Soooooo I ordered up a Seymour Duncan Hot for J bass neck position. Whoooooooooooooooa ! What a difference ! Lots of mid and sparkle with underlying warmth yet still tight and foucused. Notes on the D and G string from first to seventh fret Jump right out, always a problem area for me with Fenders. Upper register just sings. I left rehersal really liking my '08 J. I still really want a RI for the ZEPPILIN set BUT I have a deal on a 70's Hiwatt DR201 that has been on again off again, it's now on and I have to take care of that before I go buying anything else. I can't say enough about SD pickups, I have always been a Dimarzio man, would you belive this is the first SD I ever bought ?
