【Supreme Masterpiece, Rare Item】 Violin, 2020, Signed by the late Hirokazu Kubota, Chaconne. Volcanic Ash Polishing & the Crystallization of Phantom Varnish Research. This violin was made in 2020 by the late Hirokazu Kubota at "Chaconne." It has a handwritten signature on the label. It was purchased at a store for approximately 1.8 million yen at the time. This series of instruments was also featured in an NHK documentary program, shocking viewers with "acoustic adjustment using volcanic ash" and "the reproduction of lost varnish," which are the culmination of decades of research by Hirokazu Kubota, the representative of Chaconne. High quality. The program's scientific analysis detected that the sound characteristics had the same waveform as Stradivarius. It is from that series. Also, individual instruments with Mr. Kubota's handwritten signature are no longer available and are extremely valuable. Unraveling the secrets of the "sound" of masterpieces such as Stradivarius, he arrived at his unique volcanic ash adjustment. By pursuing the vibration efficiency at the cellular level of the wood and applying fine polishing, it achieves an astonishing response like a "musical instrument played for several decades" and a pure sound without impurities, even though it is new. Furthermore, he pursued "varnish that doesn't kill the sound," and the research scene was widely reported on NHK. The varnish applied to this instrument is extremely thin, does not interfere with the wood's breathing, and maximizes vibration. The low range (G string) has the depth and embrace of a cello, and the high range (E string) has a brilliance and luster that pierces through. In particular, due to the effect of volcanic ash adjustment, you will be able to experience the "professional specification" of sound that travels far, even with a small amount of force. Condition: It has been carefully handled as a collection. It maintains a good condition. Adjustments of the sound post, bridge, pegs, etc. are perfect, and you can use it at a concert immediately after it arrives. It also has the dignity of a work of art. A Swiss-made hard case is included. Currently, Dominant strings are strung, but it will be delivered with Olive strings. I would like to avoid any trouble, so please understand that no returns or exchanges are accepted. If you are nearby, I will accept auditions if the dates match.
