Had this bass for about 3 years now and its my absolute workhorse, Mines modded with an Aguilar OBP-1 pre-amp which provides bass and treble boost only (use accordingly, you wouldn't want to blow your hair off!), It has a fender bad-ass style bridge, A Hip-shot D-Tuner and Seymour Duncan Apollo jazz bass pickups, Not to mention its strung up with only the greatest strings on earth! They happen to be the Rotosound Billy Sheehan Swing bass 66 string set 43-110. Its currently in the classic sunburst colour but I'm on my way to getting it refinished in custom colour shell pink, so it has that 60's vibe. If you're looking for a bass that you can use forever and not even have to mod it (But obviously in this case, I did) this is the bass for you!
Okay, so mine isn't a REAL MIM Jazz. My bass was Squier Series made in Mexico by Fender around 1994. I believe these were extra parts from American models that were made with cheaper electronics and parts.
Still, it sat in a basement for ten years before I dug it out when I was 14. It was my first bass, and it's help up to the last 12 years of abuse, lots of shows, and some recording. I switched over to my P-Bass around 2010, but before then, this was my main bass. these basses were a bit weird, as they had a one-piece plastic pick guard instead of the pick guard and metal control plate you most commonly see. It also has the two shorter-length Jazz pickups.
I recently had it cleaned up and had the electronics cleaned. It still looks and sounds great.
