The Andrew Markworth AM1R mallets are made using Promark's proprietary mallet technology. Rather than purchasing off-the-shelf parts and utilizing outdated manufacturing practices, all cores are injection molded in house and threaded onto shafts using Promark's patented insert design for unprecedented consistency and durability.

In final assembly, all Promark mallets are wrapped using a state-of-the-art winding machine developed from the propreitary winding technology of the world's premier guitar string manufacturer. This mallet series features a variety of core shapes, hardnesses and materials to accommodate the needs of the competitive marching percussionist.
