A switchable foot pedal system for a drum-playing equipment has a hi-hat to be activated by a first pedal and a base drum to be activated by a second pedal. The shield is molded by mating first and second mold portions about first and second spaced-apart cores to define: a first annular void about the first core; and, a second annular void about the second core. The method further includes forming a plurality of cavities in the PMOS region of the substrate, performing at least one epitaxial deposition process to form a plurality of in-situ doped semiconductor layers that are positioned in or above each of said cavities, and forming a masking layer that exposes the NMOS region and covers the PMOS region.
