I have a B-Bass IV Jazz, but it's not the Jazz style copy.
It's Korean built and has active EMG Select pickups in it, and it's a decent Jazz bass.
The Selects are not my cup of tea, but I can get what I want out of the bass by using an MXR DI+ to add some color.
It's lightweight and comfortable and has a Steinberger bridge D-tuner, which is great.
Build quality is fine - no flaws detected.
I know it's not what you're looking at, but it's a Hohner Jazz...
