Created for the advancing string player, these bows feature sticks made from our own proprietary advanced composite. The bows are mounted with the highest quality German-made ebony frogs from Paulus. The frogs are fully lined with a white mother of pearl slide and double eye. All of our advanced composite bows are nickel silver mounted with a wire grip. AC bows come in Glasser high-gloss brown with premium white unbleached horsehair.
