Pretty bass: http://www.bassnw.com/Used%20Basses/alembic_spoiler_macassar_ebony_4_st.htm

That top is awfully red tinted for ebony.  Looks more like a straight-grained cocobolo to me.  But a pretty instrument nonetheless.
 
Bill, tgo

The top is indeed macassar ebony.  This bass was for sale from a store in Tennessee late last year for $900.  A fellow in Washington state purchased it & apparently didn't keep it.
 
Mica ran the specs on for me...here's the link:

I am heading down to BassNW this morining to check 'er out, although I think my sincere interest lays elsewhere.

That looks like a good deal for that upgraded top and condition.  I think you will really like it if they've got it set up reasonably.

I have some pics that the guy in Tenn sent me - the bass alot of dings & particularly the finish has taken a beating in the back.  I'm kind of picky & if it had been in better shape, I would have grabbed it for $900.  Heck, if it had been in better shape, I'd have probably paid more.  Nice top though.
