I have a MIM jazz with custom rectangular pearloid fretboard inlays. It, over this last year, has become my child. I could not bare to get a different bass, even an MIA Deluxe, but I also want to improve the quality of the bass. I have, so far, in mind to put in a Fender Custom Shop '60s J Bass Pickup Set and replace the bridge with a Fender P Bass/J Bass Vintage Bridge Assembly. The color scheme is a jet black with a plain white pickguard. I am changing out the pickguard to a perloid one to match the fretboard inlays. I have been hesitant to change the pickguard because I am thinking of putting in a "F" bridge cover. Any Ideas? Feel free to shoot down my idea's or prompt me with other equipment.
