I personally don't see the appeal in this. Like Gianni above said, you can get a cheap bass for the same price if you really want a bass sound.
Also, those "fretless" simulators always make me chuckle.
I've had a Geddy Lee Jazz Bass MIJ for several years and probably played it a total of 5 times. I hate the neck, way too thin, no shielding in the cavities...The only thing that saves it for me is the Badass bridge.
