Like all other D2 Yonberg models, the D2 Wind is equipped with particular covers, highly technical, made of a polycarbonate frame associated with an stamped and very rigid plate made of stainless steel 0.04 inch thick. These covers constitute real acoustic mirrors giving a big, bright and rich in overtones sound.
The large air intakes on the sides of covers allowing the harmonica to freely "breathe" and the conical shape of the comb resulting in a wide opening of the covers at the pavilion side, also contributes to obtain this powerful sound.
Comfort of lips is guaranteed by the ergonomics of the covers whose faces are carefully rounded and the mouthpiece is slightly curved in the longitudinal direction for avoiding to hurt the corners of mouth especially when playing in "Tongue Blocking technic".
Tuning and maintenance of this D2 Wind are simplified by the simple and rapid disassembly of this harmonica (less than one minute).
Indeed you just have to unscrew the three large 0.12 inch screws to disassemble the harmonica to access to the reed plates in the heart of the instrument. Reassembly in reverse direction is just as easy and fast as dismantling.
