I was watching some videos of Tokyo Groove Jyoshi who had guest artist Harumo Imai on saxophone. As these things go a link for Harumo playing live shows up in the list so I take it to see that the bassist in her band is playing an Alembic. 


Edit: The bass player's name is Naoki Isobe. Here is a link to his Youtube pages.

That is an Anniversary model.    I have seen his posts on Instagram
