I worked at the largest Jackson dealer in San Diego when they were at their peak of popularity, so I had the chance to play many of their top of the line basses.
I found them to be well built but dull. Jackson really was a guitar company who made wildly popular guitars (at least for a while there) and appeared to feel forced to build basses. The basses were neck-through PJs with pointy ends. I found them to have too much finish and so-so electronics. They lacked all the "modern" innovations that the guitars had at the time - in part because there really just wasn't much to innovate in a bass (there still isn't, really). I found them to be over-priced, as well.
But if you like pointy neck-thru PJs, you might well dig a Jackson.
