    I recently put in a pair of 9j1 in my MIM fender jazz. First time i played with them i was amazed at the tone but when i played with the band i noticed the output was very low i had to pretty much double my gain and even then i would get lost in the mix.
    I was wondering if there was anything i can do to bump up the output. I was told that installing a preamp would do the job. is is this true?

    A Bart Preamp will definitely do the trick. Usually with Bart pups, you'll need a preamp to boost their best qualities.
    With the MIM Jazz, you'll need a 2-band, 3 knob config, stacked for more options.
    Look here, http://www.bartolini.net/ then try http://www.bestbassgear.com/bartolini-preamps-ntmb.htm# for good prices.
    Congrats, IMO Bartolini and Basslines produce the best tone, not too bright and brittle.

    I came across the same issue... sort of. The only difference is that my bass already had a preamp, not Bartolini preamp tho. However, from I was told, Barts could work with any preamp already in the bass. My concern then is if I used soldering of bad quality (I used rosin core because I was told at Radio Shack this was good), or some wiring issue.

    Yeah a Bart preamp would do the trick, they have a gain control adjustment built in so you can boost the output.

    Just put in a Bart HR 4.5 preamp in the bass with these p.u.'s .... after messing around a little with the gain control in the preamp I was amazed. The bass beefs up pretty nicely and the tone is very clear. Love this bass even more now.
