The nut is the classic taper 1.75 inches. The preamp is original, we replaced an IC on the board and tested it out. Everything is functional and good for a 1976 bass. The electronics have not had the electronics upgrade, and the new owner can certainly have that done before we ship it out.
The bass is beautiful, plays and sounds great, and as far as I am concerned, is the archetype of Alembic basses. When I close my eyes and think of Alembic, this is what I see. Probably because I was only 6 years old when we built it and this styling made a huge impression on me.
There might be a few other very minor things the new owner may want (change the backplate to threaded inserts, replace the strap pins) but besides the electronics upgrade, there's not much else this bass needs. There's some honest road wear on it, but the front and back are largely free of blemishes, and it's a gorgeous aged color. I heart Bird's-eye Maple too!
