This is a Gottsu alto saxophone, famous for its mouthpieces. While many saxophones today aim for a vintage sound, I feel this saxophone has a unique sweetness, depth, and warmth in its tone. I believe this is largely due to the use of pure bronze and the plastic resonators. It's easy to play, of course, and the breath flows smoothly, making it easy to control and allowing for stress-free playing. It's a very good alto, and I really wanted to keep it, but since I'm using it less, I'd like to pass it on to someone who will play it a lot and cherish it. The items in the photos are the only ones included. It was adjusted around March of this year and hasn't been used since. Because it's unlacquered and has undergone special processing during shipment, it has a very cool look (with an oxidized film that's in good condition). There are no noticeable dents. I think the overall condition is good. The case is the backpack type and very convenient, but it has some scratches, so please be aware of that (no problem with use). Please refrain from purchasing if you are concerned about minor details. Returns are not accepted, so please consider carefully before purchasing. The following is an excerpt from the website: Unique unlacquered finish on bronze material The body is made of bronze (bronze), not bronze brass. Bronze brass is brass with a high copper content, an alloy of copper and zinc. Bronze is an alloy of copper and tin. Bronze is a material with a high copper content, but it is stronger and more tenacious than brass. It has a unique sweet and deep resonance of the material. By applying a special treatment to the bronze material in the final stage, a unique mottled pattern that is unlike any other in the world emerges. Plastic resonators are used. This is a particular point of focus in modern saxophones, where metal resonators are becoming the mainstream. It produces many overtones and a soft, warm tone. Reinforcement parts that are slightly larger are used for the neck and U-shaped tube. They play a role in supporting the smooth flow of breath. They contribute to the powerful tone. The thumb rest and thumb hook are made of metal. They increase the vibration efficiency of the tube, and while the tone is mellow, they achieve power that can compete with other instruments.
