Hey everybody, I got an early christmas present-I got to upgrade the pickups in my 2000 MIM Jazz. I have the DiMarzio Ultrajazz pickups, wired to 250K push'pull volume pots (put in a good tone pot while I was at it.) All I can say is, BIG improvement over the stock single coils. Good botton, nice highs, and no single coil noise! In series mode, this bass sounds very fat. Especially using the neck pickup, with the tone rolled off a bit. I use TI jazz flats, and I love the sound. With a pick, or fingerstyle-this thing sounds incredible IMHO. I think a set of Model J's will find their way into my 2002 MIM fretless, because they have more of a midrange boost than the ultrajazz does, according to Dimarzio's website. I want to say while I'm here-I got my pickups and pots from Brian at bestbassgear.com I'am vey pleased with the service I got from him-ALWAYS replies to you quickly, is very friendly, and got the pickups and pots to me within 2 days. A local guy here on the Cape put them in, using a wiring diagram I got from Dimarzio. So, the bottom line is-I'm a happy camper with my MIM fretted jazz now.
