I think we have seen pictures of this bass in threads before but hear what the owner has to say about it.

 Hello    The fellow who had this built by Alembic  was an old friend of mine from the early 1970s . There is already a thread about this that I just posted in and wrote some background reflections .

Here it is ;
Video ! Prairie Sun Recording -- 1975-1976 Alembic 5-String Bass !

Can a moderator please remove this thread as Sonicus has posted a much more informative one and it keeps things in one place. Thanks

Hello Jazzyvee  . I hope that all is well with you .I just commented in the posting with some reflections .
