Doesn't mention weight anywhere - as a previous Alembic owner I've discovered so many of them to virtually ungiggable because of weight and atrocious neck dive.
This one ought to balance better than most and the headstock design is far nicer, IMHO, than the triangle design you sometimes see on Orions.
They don't hold value well though. This would have been close to £3,500 new for whoever owned it &, if it's a commission sale or was PX'd, then he's looking at about £1,500 after only 3 years
