Looks stunning, but I've just done some research and the reviews are not good, here's a couple of examples from "Talkbass":
Those were an early experiment in combining piezo and magnetic pickups and are rare because they were a bad design that was pulled from the market quickly.
They just didn't work very well.
By modern standards the electronics were pretty terrible. It had a master volume, piezo/mag blend and a single EQ knob with a center stop.
No separate battery door, at least 4 screws to remove to get to the battery.
Inside, the battery was just sort of flopping in the cavity, wrapped in foam. No clip to hold it in place.
And they're very difficult to intonate because of the acoustic-style saddle.
Since it has just one saddle for all 4 strings, it makes intonating the instrument a game of compromises. Since the saddle is straight, where the length of the strings isn't, makes that some strings will be sharp, and others will be flat. And because it's an acoustic bridge (a piece of wood glued to the top), you can't make any adjustments in terms of intonation when you change for a different brand/gauge/material of strings. I played one, and while not terrible, it wasn't great either. Like mentioned before, the electronics are sub-par compared to contemporary standards, the sound is nothing spectacular (and downright cheap on the piezo), but it's built well, as can be expected from Fender Japan.
