I owned this instrument in the 1990s.
Can anyone offer information about this mysterious Alembic,
original owner,or present whereabouts of this bass guitar?

Wow! And I thought I was cool with my 5-string Stanley! 


Hope you can track it down! I've been on this forum for over 15 years with an interest in the Stanley Clarke models and variations and don't think I have ever seen this one, but hopefully it will turn up.
