Righto here I am!
First of all, it looks like a lovely bass, congrats. Where did you buy it?
It’s a series 1 bass, before Patrice started using carbon fibre necks. The brass laminate runs along the neck and although it’s a bit heavy it’s a really good system. I had a series 1 fretless which I recently sold but never had to touch the truss rod once I had set it up.
There should be a serial number above the rear strap pin but it’ll probably be before Patrice started recording them against the date (there’s a spreadsheet on the Vigier site but think it only starts with series 2 basses). In that case, the year and date of manufacture will be under a pickup, usually the neck one.
Assuming the electronics are original then they might feel a bit buzzy by modern standards however they can be cleaned up and working flawlessly. It’s a really nice sounding filter preamp which is attached to some awesome Benedetti pickups.
Enjoy it - it’s hard to find a decent one of that vintage that doesn’t have any finish cracks, butchered electronics or knackered truss rod adjuster.
Anything else I can answer for you?
Cheers
