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, Gamma® 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 reed-plates that are equipped with Gamma® reeds are also available in a special “ultra-reactive” version for high level players. High precision and progressive depth millings that are adapted to each reed have been realized in the reed-plates.
These arrangements provide a great sound power, an instantaneous responsiveness of the reeds and an incredible facility of triggering notes.
This option is for high level harmonica players who can play with great velocity. Less experienced players will not be able to appreciate this option which is therefore of little interest to them.
