Just a note on truss rod covers,
The early production basses and guitars have no truss rod covers....

This bass is from the period they did not have truss rod covers.

Interesting.  The numbers in the Top 25 article don't match the numbers in their 2015 Price Guide:
 
Series I: $3600-4500
Series II:$4200-5200
S. Clarke: $4600-5800
 
My favorite part is this description from the article:
 
The original Alembic bass, with the ?omega? pointed lower body designed to force the player to use a proper stand! Offered in three scale lengths and different wood combinations, this is still the classic ?70s Alembic of many player?s dreams.
 
Love that Omegal Point!  Much better than that pointed Omega that looks like someone took a bite out of the bottom!  lol
 
Bill, tgo

Bill. you present a valid , point.

 
I prefer the triple point body (like Jerry Only)
 
I resized the pics from the op:
 
 

Love Birdseye!  Beautiful!

Very nice!

Lovely Bird's-eye Maple! I like the gentle quilted figure too.  
 
Are there two truss rods or is the one just off center?

And if anyone is curious about jason Mercer(see provenance letter above):  http://en.wikipedia.org/wiki/Jason_Mercer

I see that the address info in the letter to Jason Mercer has now been redacted.  it wasn't my intention to draw attention to that info - now 25 years old, and i expect no longer accurate - but to give members a chance to see, once again, how Alembic basses - or their users at least - are so well represented in the industry.  Jason is a great musician, and his work with Ron Sexsmith is as solid as  a rock.  Anyway, this was a bit of hijack, for which I apologize.

Thanx! And sorry for that...

Hi, guys - first of all, thanks for the very valuable help.
 
Secondly - how do I know if this is Series 1 or Series 2?

It looks to be a Series One, due to the switches that allow you to choose preset points for filtering.  If it was a Series 2, there would be chicken heads instead of switches, which would allow you to vary the points of reference.  Series One instruments are great, Series Two gives that 11 factor as stated by Nigel Tufnel of Spinal Tap fame.  Enjoy the bass, Alembic reigns supreme.

Thanks, TP!  You guys have been awesome. And I would never dare question the expertise of Nigel T.

Jim Marshall did... And Tufnel agreed: :-)
