For a while in the 70's my brother had an obscure 60's violin-body bass around the house. I looked for it a while back but couldn't find it. I remember that the pickups were incredibly microphonic, but I now know enough that I could replace them easily. The body and neck were actually good.
No luck, long gone after the parents moved from the big country home to the smaller home in town. No big loss, either.
I had a Rogue VB-100 for a while, and it was actually a pretty nice bass. I had no problems with it, just lost enthusiasm for it and sold it. Maybe should have kept it, but I'd still be ignoring it if I had.
