Hi, I bought this alembic several years ago, but I forget the details, I have just been playing it.
What information do you guys have on this lefthanded 4 string?
Welcome to the forum, Ivo.
These serial number lookups normally take months to hear back on (the info is kept on paper cards in a filing cabinet).
If you'd like a few guesses, post a couple pictures and most here will be able to nail most of the build details (wood type, electronics, etc).
Enjoy that bass!
