The Fender jazz was my first decent bass,i paid £269 for 75 4 bolt in 1983.The neck was super slim the action low and a dream to play.The next few years everybody started playing Wal,Status,Steinberger,jaydee etc and the humble Jazz was very uncool.Luckily i avoided temptation and stuck with it and they have took over the world again.Each to their own but i think a lot of bassists try to over complicate things,perhaps trying to take the guitar guys on.Always had compliments on my bass and the sound.Eventually parted with it to get a 76 with rosewood block neck instead of maple and thats also a great bass.
I think the Jazz is the female to the Precisions male.
