^^ Re. questions about replacement pickups, some posts up, I can't speak to the original pickups since, when I got my (Power) Jazz Bass Special, it had already been modified with active EMGs and a passive VV/TT setup. The EMGs served me well for a long time. Eventually, I replaced them with a set of Reed James pickups and replaced those with a set of Wilde/Bill Lawrence pickups, which are in there now and are my favorite, overall, of the three sets. They're wide (voicing) and just a bit modern-sounding, but more full and more organic sounding, to my ear, than the EMGs.
On my bass, I had to sand the casing of the neck pickup some, in order for it to drop in the route (bridge dropped in fine), which was a pain, but, now that it's in there, I enjoy the pickups a lot. They're responsive (dynamics are clear and low notes don't mush-out or lose focus) and well-balanced without being clinical or harsh.
