Our D1 and D2 diatonic harmonicas are equipped with Gamma® reeds which are a new technology developed and patented by Yonberg. Completely made in France, these reeds are made either in a brass alloy with excellent mechanical characteristics, or in a stainless steel offering high performance.
The registered specific shape of these reeds is very innovative. In fact, in comparison to traditional rectangular reeds fitted to all models on the market, Delta® reeds are characterized by curvilinear longitudinal sides, associated with an enlarged triangular base.
The unique design® of the Gamma® reeds as well as the very particular mechanical working procedure explain their exceptional durability.
Their degressive shape generates a warm, powerful and very rich in harmonics sound that characterizes the “Yonberg’ sonic signature”.
The Yonberg’s reedplates that are equipped with Delta® reeds are also available in a special “ultra-reactive” version. High precision and progressive depth millings that are adapted to each reed have been realized in the reedplates.
These arrangements provide a great sound power, an instantaneous responsiveness of the reeds and an incredible facility of triggering notes.
