That would be a great 6 stringer to own.
That top wood is incredible. Is it some kind of walnut?

1992 Alembic Europa 6st Fretless Model Crown Headstock Electric Bass w/HC

I always felt; 4 strings/ 4 fingers - meant to be.
I look at this beauty and see; a string spacing that isn't crowded; a neck (from the back) that is thick and elegant; a top wood that is fluid and know that the electronics are pure genius.....

Another lust worthy instrument.

Beautiful instrument which sure looks like walnut to be me.  I'm looking for a fretless too, but alas I already own a 6-string Europa which doesn't get much use due to its wide neck (or my stubby fingers). I love Pauldo's reasoning and should have listened to it prior to purchasing the 6'er.
