You're looking at a good Greco Violin Bass Guitar made in Japan. We don't know anything else about this other than we think it's a 60s/70s era. Everything works properly. The electronics were recently cleaned up (though the switches are still a bit scratchy), a proper setup was performed and a fresh set of flat wounds have been installed.
The pickguard is missing and the input jack looks like it was replaced. The finish has checking and hairline cracks.
