I have just seen this epic on one of the alembic groups on facebook, but there are few things about this bass look odd to me.
Firstly the jack socket is more in line with the top of the tailpiece where than others ive just checked out on line have the socket much lower down towards the end of the bass. The position and layout of the controls are non standard. There does not seem to be a logo on the headstock either. Any other views?

The headstock appears to be wider than usual, and the LED's are not positioned where they usually are... but, who knows?

Body shape is wrong. Looks like a knock off.

There was a thread about this one a while back... just can't remember how it was titled or what came of it. I do remember there was a question of legitimacy. I agree, lotta' weirdness there. Hard to see enough detail on this device to know how much is actually Alembic.

*here is the old thread I was thinking about, but it doesn't look like the same bass. It does however have some similar traits.http://club.alembicguitars.net/index.php?topic=23736.0

Perhaps ask the owner if there is a serial number.

This is not an Alembic bass.
