Our harmonicas are equipped with Gamma® reeds which are a new technology developed and patented by Yonberg.

Completely made in France, these reeds have excellent mechanical characteristics and offer high performance.

The unique design® of the Gamma® reeds as well as the very particular mechanical working procedure explain their exceptional durability.

They generate a warm, powerful and very rich in harmonics sound that characterizes the “Yonberg’ sonic signature”.
