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

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

Their specific and innovative shape of these 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”.

A special “ultra-reactive” version of the Gamma® reeds is available and provides a great sound power, an instantaneous responsiveness and an incredible facility of triggering the five highest reeds of both reedplates.
