I am offering the CODA BOW DIAMOND GX, perhaps the most famous and well-regarded carbon fiber bow. The retail price is 220,000 yen (Kurosawa Musical Instruments). You can find a description on their website, so please feel free to search for it. As an additional explanation, I have translated the important parts from the official CODA BOW website into Japanese. -------------------- The CodaBow Diamond GX carbon fiber bow is a stunning homage to the great performance bows of history, delighting with a tone that combines warmth and power. With a refined acoustic core, traditional weight and balance, and high responsiveness, it achieves a professional and expressive bow that is sensitive to the delicate commands of the hand. It is compatible with a variety of playing techniques, effortlessly playing both quick, articulate strokes and uniform, resonant long tones. The CodaBow Diamond GX bow blends naturally into ensembles and shines for soloists. Unmatched by other bows, the CodaBow Diamond GX is loved by professionals of all genres around the world. -------------------- This bow performs wonderfully, as its reputation suggests. I purchased it after seeing a professional's video impression, and it exceeded my expectations. The first advantage of a carbon fiber bow is its durability. It won't break like a wooden bow if dropped. You won't accidentally bump the head against a music stand and split it in two. That provides a great sense of security. The fact that it is unaffected by humidity and that the playing feel is always stable is also an advantage that wooden bows do not have. Considering the above advantages, I used to think that the sound quality of wooden bows was definitely superior, but that's not necessarily the case with CODA BOW's high-end bows. Of course, it is inferior compared to a pernambuco bow that costs around 1 million yen, but when comparing the GX to a pernambuco bow in the same price range, I feel that the GX is superior. The quality of carbon fiber bows has improved that much. I am offering it at a lower price than the store, so please consider it.
