I've had this bass for quite a few years, mostly because it's a beautiful instrument and someday I hope to play well enough to do it justice.  It would be great to know its history.

Hi Alex and welcome to the forum! We like pictures too if you have any you'd like to post   is dedicated to the Essence bass if you'd like to post there.  Mica will get to the look-up from the original paper files and will get it posted for you but it does take time.  In the meantime there is a lot of conversation here regarding Alembic, hope to see you around.  Play it Healthy, Art
