MK Pro Alto A Whistle, Black

First launched in 2003, the MK Pro has become a firm favourite with musicians around the world. Its tone, playability and appearance have set it apart from the crowd. Avoiding corner-cutting processes like moulding, casting or pressing, it's just down to superb craftsmanship and a design which offers the best possible combination of characteristics: tone, timbre, back pressure, air requirement, tuning, ergonomics, reliability (no blocking) and general feel.
