The more expensive Zager Guitars (ZAD 900 and ZAD 80) have a headstock made with Indian Rosewood, while the cheaper models (ZAD 50 and ZAD 20) have headstocks made of African Mahogany and Mahogany respectively. The necks for the whoe Zager line are made from Mahogany, but the quality of the Mahogany increases as you go up the range.
