When I first seen this bass, I instantly liked the look. I bought it to be my experimental platform for flatwound strings, and intended to change the pickup straight away. But the stock pickup sounds fine to me, and an overall quality is very good, so I decided not to modify anything.
For this price it is really hard to beat.
Update - I installed a push pull for a series-parallel connection of the coils. This humbucker has 4 wires, so you could easily do it. It has the same color wires as seymour duncan, so just look for the wiring diagram on seymour duncan website, called Jazz Bass series wiring. As it seems, it was wired a parallel before, hence the output was average. Now it has also an additional "real" humbucker sound. Highly recommended and easy mode.
