That's a beauty, Congrats! All Alembics are made to order so whoever originally bought the guitar wanted 5 strings, even though it's a specific model. You still can have things your way, weather you specify one thing custom or a bunch, sky's the limit. Pierre, look at the end of the fingerboard: the strings balance really well across the width of the board, giving more room for the lower and thicker strings. The tailpiece goes where it has to as a compromise so that the strings go straight off the bridge. A minor cosmetic issue.
