Boyesen Pro Series dual-stage reeds combine a carbon-fiber top reed with a fiberglass bottom reed for unrivaled performance. The carbon-fiber top reed has excellent response characteristics that provides even quicker acceleration, stronger throttle response, and more over-rev than our standard Power Reeds. The fiberglass bottom reed provides stability and longer reed life. To summarize the overall performance benefit to Boyesen Pro Series reeds in one word, they are simply RESPONSIVE! In this regard, improved throttle response is precisely what Boyesen Pro Series reeds deliver!
