Wow, thanks for the quick answer.
I was not really interested by this bass but a bit confused about pricing used alembic bass. I understand better now.
And you are right, alembic are very expensive in Europe and also very hard to find. But i have had the luck to listen an old serie 2 in a shop ( around 3900 euros/4800$ )and that was great.
Since then i keep an eye on ebay for a cheaper alembic model.

The only Alembic bass I ever had the opportunity to test drive was pretty similar to this one.I would love to purchase this one,even without the electronics upgrade, but I'd like some more opinions/thoughts from the club members before jumping in.The seller's asking price really is'nt an issue for me..

If the bass calls out to you through the computer screen, then buy it. If it doesn't, keep looking.
That's about all the advice I can offer.
