The Mars’ big, loud tone comes from its heavy, volume-generating, aluminum comb. Kongsheng puts its best phosphor bronze reeds in this harmonica, and then they gap them for optimum, professional performance. This harmonica is road-ready to take on the toughest taverns and please the baddest blues fans on Saturday night, and then lead the most passionate worship service on Sunday morning. Ergonomically designed for comfort. Modern look. Exquisite fit and finish. Round holes provide the most natural, ultimate connection between lips and instrument while offering the most efficient wind channeling.
