Very true, it didn't take off at all. I wonder whether that was because it was no good, or because people didn't like the look of it. As Ubit says, he wouldn't even consider one because of the aesthetics.

I had a Westone Rail for a while. As a means of demonstrating just how massively important pickup position is to tone, it was very impressive indeed.
However, it remained a cheap bass with cheap pickups, and it sounded cheap. I did some research at the time and it was clear to me that Westone designed it more-or-less as a novelty item and were quite surprised by even the limited amount of success it enjoyed.
I for one would love to try the same design but done "seriously" ... i.e. with good-quality components (especially the electronics) and using proper double-ball-end strings.
Can't comment on the Grabber except to mention its legendary shoulder-crushing weight.
