Tuned Thai Gong Extra High Octave c" Used This is the lowest c in the extra high octave (the highest c in the high octave). It is a used item, but I believe it is in a condition that hasn't changed much since it was purchased new. I have played it with felt-wrapped, yarn-wrapped, and cotton-thread-wrapped mallets. I have not used hard mallets made of metal or plastic. For reference, I have included images taken 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 or exchanges.
