Tuned Thai Gong High Octave g#' (a♭') Used Purchased new from a percussion instrument specialty store in Tokyo. It is a used item, but I believe it is in a condition that has not changed much since it was purchased new. I played it with felt-wrapped, yarn-wrapped, and cotton-wrapped mallets. I have not used hard mallets made of metal or plastic. For reference, I have included images measured with a tuner. As a characteristic of the instrument itself, it contains many different overtones, and the pitch is not as precise as that of a keyboard instrument. Audibly, it sounds close to the appropriate pitch. Please understand the above points and purchase with no returns and no claims.
