From A&F:
All snare drums are made from our patented raw copper shells, brass lugs and hardware, and Remo Ambassador heads.
We hand cut, roll, weld, and sand our exclusive raw copper shells and raw brass hoops, hand cut bearing edges and snare beds, and treat everything with our exclusive patina formula to jump start the aging process. Then we add our patented raw brass center-mounted lugs, hardware, and finally Remo Ambassador heads.
