The Yonberg's innovation

The Quick Dismantling System (QDS) concept, developed and patented by Yonberg, is based on the use of very rigid covers connected by three screws passing through the entire instrument which firmly clamps together the comb and the two reed-plates.

To completely disassemble the instrument, simply unscrew the three “big” M3 screws thanks to the screw driver included with harmonica for direct access to reeds for maintenance and adjustment.

Reassembly in reverse direction is just as fast and easy as dismantling.

Gamma® Yonberg’s reeds: precision, durability and sonority!

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 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 reedplates that are equipped with Gamma® 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.

The Yonberg's expertise

Ergonomic design

One of the big advantages of the Yonberg harmonicas is their unique trapezoidal shape which allows a very natural grip. It avoids, in the dark, the risk of taking the instrument in the wrong direction. It also makes it much easier to hold the microphone in the palm of the hand.

Power

The extremely rigid covers of our harmonicas are real acoustic reflectors offering a warm, unique and rich in harmonics sound. The large opening of the hoods, made possible by the conical shape of the comb, as well as the large side openings allow an optimal sound power.

Comfort

All edges are rounded and the mouthpiece is slightly curved for additional comfort on the corners of the mouth. The index finger fits perfectly into the grooved cover plate, allowing plenty of room to put the harmonica well into the mouth. Great for “Tongue Blocking” playing.

Airtightness

The hourglass shaped channels accelerate the airflow at the middle of the channels and prevent air leakages along the longitudinal edges of the reeds. The semi-elliptical chambers at the bottom of the channels ensure an optimal flow of air. Both covers enhance the airtight seal.
