Thanks very much.
It's a very nice bass indeed. I paid 2 150 Euros (1400 UK ? - 3000 US $) for it in 1990, which was a good bargain I believe. The body is semi hollow. Serial number is 77 - 617.
I have a few things to replace from the onboard preamp but it's very difficult to find someone in France capable to repare this kind of bass and also to obtain spare elements (jack socket, pickups...). So if anyone can help with some good addresses throughout Europe, that would be really helpfull.
Thanks everyone for such nice welcoming on the Alembic club.
