Master Key A-440 Chromatic Pitch Instrument Vintage

This vintage A-440 Chromatic Pitch Instrument is a remarkable find for collectors and musicians alike. Estimated to be over 50 years old, it remains in very nice condition and comes housed in its original box. The instrument features a dual finish—polished chrome on one side and black on the other—showcasing both function and design. Built without moving parts or mechanisms, it is engineered to stay in pitch forever, a testament to its enduring quality. It offers 13 keys covering the full chromatic scale (Scale F), and the original directions for use are still included inside the box. While the box shows signs of age and wear, the instrument itself has been beautifully preserved. A fine addition to any collection of vintage musical instruments, this piece represents both craftsmanship and history.
