All of our instruments are made with careful attention to precision in our factory in Tianjin, China. The workers are all superbly trained directly by Mr. Zhao. The Di Zhao flutes are all padded with Pisoni pads, and all pads are partially shimmed like professional flutes. All instruments are made to achieve smooth key action, fast response, and excellent resonance.
All of our instruments are assembeld, tested and adjusted by Di Zhao in the United States before being shipped. Each headjoint is specially hand-cut and feature silver risers, yet another feature that makes Di Zhao student models play like professional handmade flutes. ALL Di Zhao flutes are tuned to pitch 442. The wood in our grenadilla flutes has been carefully selected, treated, and seasoned to resist changes in temperature and humidity.
