The tremolo is the most commonly used harmonica in Asia. The Asian tremolos have a "dry" tuning, in contrast to their European cousins, which are generally much "wetter" tuning. Tombo, the Japanese company responsible for the Lee Oskar model, are the leading Asian tremolo harmonica manufacturer.
Seydel have now thrown their hat into the ring, releasing a high quality Asian style tremolo harmonica, with stainless steel reeds. It's called the Skydiver, the Tony Eyers Trio use it here for the tune "Mominette"
