I am the original owner of this instrument.  In fact, this bass was featured in the Alembic catalogue as a Series I back in the late 1980's. I added red side LED's and upgraded to Series II electronics at purchase.  It always had a 7 piece purple heart/maple neck so it was destined to become a Series II all along!  Long scale 34 neck, oval inlays, gold hardware.  Power supply and 5 pin cord, bookmatched top, back, and peghead.  This Burl Maple is beautiful and the condition is near mint.  Make me an offer I can't refuse.  Asking 12k.  Retail is more than double.      

Here it is in the Alembic catalogue: http://www.fcbass.nl/alembic/images/catalogue/images/895.jpg

what year of birth exactly ? what year of upgrade ? neck ?

sorry 89 :-/

My warranty card shows date as Dec 21, 1989.  Serial # 89-5697.  Upgrade was done at time of purchase in 1990.  It has a 34 long scale ebony neck with oval inlays.

hardware look to be brass ?! not goldplated or it's the pictures ? possible to have biggert and closer of the body top and back ? Neck is perfect ? no buzz, no truss rods lost ?

Tuners and strap pins and locks are gold Schaller.  Backplates and tailpiece is brass.  Dual truss rods are perfect.  The neck and frets are perfect as well.  This bass was never my primary instrument so it is in remarkable condition.  I took extreme care.  Looks as good as the day it was shipped.  Pierre, send me an email and I will send pix that you can zoom in.

what a beauty. Wow.

done ;-)
